The German walk-behind tractor Profi is the embodiment of power, reliability and versatility. The unit was designed specifically for processing the most difficult soil, performing various works on a personal plot and within the city. Motoblock Profi 1800 is the ideal solution for those who are tired of hard physical labor.

Today, the Profi 1800 MB walk-behind tractor is a recognized leader in the line of heavy agricultural implements for personal use. All units and mechanisms of the machine have such a large margin of safety that in terms of reliability it can compete with a light mini-tractor. At the same time, the cost of the Master Profi 840 walk-behind tractor is an order of magnitude lower than such a product.

General aggregate properties

The petrol walk-behind tractor is designed and assembled with typical German pedantry. The Profi 1900 walk-behind tractor is produced under license in the countries of Eastern Europe, CIS and China. The quality assurance of finished products is the strict control of Profi representatives. Before leaving the production shops, all products are checked for completeness and completeness.

The walk-behind tractor is equipped with a powerful and reliable Japanese engine Honda AMS 190F. The power plant with a vertically positioned cylinder operates stably in extremely low and high ambient temperatures. Forced cooling prevents the motor from overheating, even during prolonged operation in summer heat.

Particularly noteworthy is the engine power, which is 14-18 horsepower (depending on the model). The incredible traction force developed by the Profi KB800-2 walk-behind tractors allows you to cope with the most difficult tasks that only expensive special equipment can handle.

German designers have applied an innovative approach to the creation of the transmission of the Profi G-192 heavy walk-behind tractor. The modified SGS2 + gearbox (Shtenli Gear Shift 2+) provides smooth and smooth gear ratio changes. The gearbox and gears are made of durable carbon steel. All transmission parts are abrasion resistant and have a long service life.

The undercarriage of the Masterprofi walk-behind tractor is also noteworthy. The presence of a differential makes it easy to maneuver around corners and in tight spaces. The Profi 1900 has excellent track control, staying in track even without operator control. Wide wheels large diameter have good adhesion to the ground. The use of extensions allows the wheelbase to be extended up to 90 cm, which improves the stability of the unit on bad roads and on slopes.

The Profi 1900 walk-behind tractor is adapted for the most comfortable driving. All control levers are located on the steering column and fit comfortably in the hand. The column itself is adjustable in width and height to suit the size of the worker. There is a glove compartment on the body for storing spare parts, tools and rags. All components and assemblies are protected by covers, and the wheels are protected by special discs. The machine is completely safe for the operator and surrounding plants.

Specifications

In specialized stores, the received cars are removed from the packaging and checked. Only then are they put up for sale.

The manufacturer declares such specifications Profi 1800 Pro Series models:

• engine - four-stroke, single-cylinder, 420 cm³;
• power - 18 hp;
• fuel tank volume - 6.5 l;
• fuel consumption at low / full load - 1.3 / 2.4 l / h;
• number of gears - 3 (2 forward, 1 reverse);
• wheels - pneumatic 6.5-12.00;
• dimensions (length / height / width) - 1750х1300х900 mm;
• weight with full fuel and oil filling - 180 kg.

The Profi 1400 has a power output of 14 hp at almost the same performance. The use of machines of this type is justified when working under normal conditions where increased torque is not required. But the Profi 1030 walk-behind tractor with a low gear can even cope with virgin soil.

The standard complete set of the Profi walk-behind tractor consists of the unit itself with wheels, a cultivator (cutter), a hitch and protective shields on the wheels. The product comes with a user manual and a warranty card. The kit includes a set of tools and accessories for assembly, disassembly and maintenance of the unit. In the basic configuration, Profi walk-behind tractors are used as motor-cultivators. In order to expand the area of ​​their application and work efficiency, it is necessary to acquire additional options... This can be done immediately when making a purchase or as needed.

Auxiliary equipment

The walk-behind tractor body is equipped with universal brackets for attaching all types of attachments. The power take-off shaft transfers power to the auxiliary equipment through a belt that is attached to the pulleys. Owner reviews indicate that the unit is adapted for options that are produced by almost all domestic and foreign manufacturers.

Expansion of the functionality of the walk-behind tractor is achieved by installing such additional equipment:

• Hillers. Hillers in disk and arrowhead design are attached to the hitch. By their design, these devices are divided into single-row and double-row. Hillers cut the weeds, shape the beds and loosen the fertile soil.




• Plows. One body can accommodate 1 or several plowshares. The machine plows even the most dense soil to a depth of 30 cm. In households, the plow is used for primary soil preparation, ditching and trenching.




• Mowers. Rotary mowers are used to harvest hay, clear the field from bushes and weeds, and domesticate the local area. The productivity of rotary devices with two knives is up to 0.2 ha / h.




• Snow blowers. The owner of the Profi unit with the help of a rotary snow blower can clear paths, platforms and paths from dense snowdrifts up to 40 cm high. Brushes and a front blade are used to deal with fresh snow.

To extend the resource, each new walk-behind tractor must go through the appropriate commissioning procedures and running in before operation.

I. Preparation and inspection before commissioning and running-in (1) Retighten the connections of all tractor parts.

(2) Fill with fuel, lubricating oil and coolant.

(3) Check and adjust the tension of the V-belt.

(4) Check the tire pressure.

- & nbsp– & nbsp–

Note: "Load" means the power of the tractor with normally working gears of the gearshift mechanism.

Note: During break-in, check the braking system and steering several times and make sure that the working mechanism is working properly. (2) After commissioning and running-in tests, change the engine and transmission lubricating oil. Subsequently, carry out maintenance and inspections according to the instructions in this manual.

- & nbsp– & nbsp–

I. Clutch The motorized cultivator is equipped with a dry clutch of the frictional type of constant engagement. Its construction is shown in Fig. 3.

The clutch consists of a driving part and a disengagement system.

The function of the clutch is to engage and disengage the drive from the engine to the gearbox and working mechanism. In the event of a sudden external overload, the clutch slips, thus preventing damage to other parts and components.

When the clutch handle is in the “disengage” position, the clutch control pull rod moves the yoke in the opposite direction, pulling back the ratchet and allowing the release bearing to move axially. The release bearing presses on three release levers, which lift the three adjusting rods upward, causing the pressure plate to move to the right and cause slippage between the pressure plate and the drive plate assembly, thereby interrupting force transmission and disengaging the clutch. When the clutch handle returns to its original position, the three release levers move axially in the opposite direction and the pressure plate pushes against the drive plate assembly, resulting in clutching and force transmission resumed.

II. Gearbox The motorized cultivator is equipped with a gearbox (3 + 1) * 2 combined type with spur gear transmission. Its construction is shown in Fig. 4, and in Fig. 5 shows how each gear train is engaged.

Rice. 5. Kinematic diagram of gear shifting III. Brake A ring-shaped brake with inner pads is used. Its construction is shown in Fig. 7.

When the brake / clutch lever is in the "braking" position, the pull rod (1) causes the brake rod (2) to rotate, and the flat head at the end of the brake rod shaft (2) pushes the annular brake clutch (3) apart, causing the ring to rub against the inner surface rotating wheel (5), due to which the braking effect is achieved.

IV. Steering mechanism The motorized cultivator is equipped with a locking mechanism with a swivel collar.

When one of the steering knobs is turned, the steering fork and the corresponding lever are actuated using the pull rod, which displaces the gear of the steering mechanism and disengages the gear with the internal teeth, as a result of which the force on one side of the drive wheel is weakened and the ability to control a motorized cultivator is provided.

- & nbsp– & nbsp–

Chapter III OPERATION I. Preparation and start-up (1) Make sure that the amount of grease, diesel fuel, coolant and lubricating oil in the gearbox is as specified in the operation manual.

(2) Check that the bolts of the main parts and components (especially the connecting bolts of the frame, transmission case, drive wheel, etc.) are properly tightened.

(3) Move the brake / clutch handle to the off position, the gear lever to neutral, the throttle handle to the start position, and the throttle switch to the open position.

(4) Start the motorized cultivator according to the instructions in this manual.

II. Starting (1) Move the gearshift lever to the desired position.

(2) Check the connection of the steering gears located on the right and left side (test method: without using the steering lever, turn the left and right handles until the cultivator is unable to move - this indicates that the steering wheel clutch is engaged).

(3) Add throttle (low idle rpm), slowly and smoothly release the brake / clutch handle and move it to the “on” position, then start the motorized cultivator.

III. Selecting and shifting gears (1) For cultivation in the field, it is recommended to select gear I or gear II, since operating in higher gears can overload the cultivator, which is fraught with a significant reduction in its service life.

(2) Gears III and IV V and VI are most suitable for soft soil cultivation.

~ 12 ~ (3) When shifting to high-speed gear, first disengage the clutch, then move the gearshift lever to the required position and activate the required gear.

(4) When changing to a high speed gear from a low gear, you will first need to add throttle to increase the engine speed, and then change the gear. Conversely, when changing to a low speed gear, to ensure reliable drive and avoid damage to the gear train, you will first need to slow down and slow down.

IV. Steering (1) Release throttle.

(2) When driving down a steep incline, pull the left handle to turn the motorized cultivator to the right, and pull the right handle to turn to the left.

V. Reverse Move the brake / clutch lever to the "off" position and the shift lever to the reverse(reverse), then with a smooth and confident movement, move the clutch handle to the “on” position and back up at low throttle.

VI Braking: quickly move the brake / clutch lever to the “braking” position and release the throttle; if the motorized cultivator is operated with a trailer, depress the brake pedal at the same time. The general rule of thumb is to avoid parking the motorized cultivator on slopes. If this is still necessary, turn off the engine and engage gear, then install thrust blocks under the tires and perform other procedures that are usually required in such cases.

(1) When starting the motorized cultivator, do not use the brake handle and the steering handle at the same time, and do not start the machine at high speed.

(2) After starting the motorized cultivator, let the engine idle for 3 ~ 5 without operating under load until the diesel engine is in good technical condition.

(3) If the engine makes unusual noises during operation, stop the motorized cultivator immediately and inspect it for possible malfunctions... Do not resume work until you are sure that the diesel engine is in good technical condition.

(4) When changing gears, first disengage the clutch. When working with the clutch, remember that it is disengaged quickly and confidently, and engaging slowly and smoothly, without jerking.

(5) It is forbidden to make adjustments and repairs to rotating parts on a running motorized cultivator. Operators should not perform any adjustment procedures on important parts and components (pressure and ignition timing, governor settings, etc.) without sufficient knowledge and confidence in what they are doing.

(6) Fuel and oil should be added with a 48 hour margin. Tools and accessories for refilling oil and fuel must be kept clean.

(7) Use the throttle valve properly and add throttle smoothly to avoid overshoot. With a short-term unit, shift the gearshift lever to neutral, the clutch handle to the “off” position, and the engine to idle. Stop the engine if it is expected to be parked for a long time.

- & nbsp– & nbsp–

Chapter IV ADJUSTMENT PROCEDURES I. Belt Tension Adjustment (1) Adjustment Requirements: The length of the two V-belts (B1800) must be equal.

After tensioning the belts, press each of the belts in the center section so that there is a deflection of 15 ~ 20mm.

(2) Method of adjustment (Fig. 8): unscrew the four bolts (2) under the frame, and by turning the adjusting bolt (1), adjust the position of the engine. After the belts are tensioned to the required level, tighten the bolts (2).

Rice. 8 Adjusting the tension of the V-belts 1. Adjusting bolt; 2. Bolt

~ 14 ~ II. Adjusting the clutch (1) Unscrew the lock nut (7), adjust the length of the clutch pull rod (2) and move the brake / clutch handle to the “off” position, which will disengage the clutch completely (Fig. 13). When moving the handle to the on position, the clearance between the release bearing (688908) and the release lever should be approximately 0.3 ~ 0.5mm.

(2) As the friction disc wears out, the clearance between the release bearing and the release arm may increase. In this case, you will need to move the brake / clutch handle to the on position. If the clearance between the release bearing and the release lever has increased, it is necessary to adjust the position of the hex nut on the screw rod so that the clearance does not exceed the range of 0.3 to 0.5 mm (Fig. 7). The clearance between the heads of the three release levers and the release bearing must be the same. The amount of clearance can be measured with a feeler gauge used to adjust the intake and exhaust valves of the engine. After completing the adjustment procedure, tighten the lock nut.

III. Brake Adjustment (Fig. 9) (1) Adjustment requirement: The brake / clutch handle moves to the position by 20 ~ 30mm. for the "off" position, which leads to braking of the motorized cultivator. When the handle is in the "on" position, the brake is completely disengaged (in this case, the pressure spring 5 of the brake is released). When the handle is in the "brake" position, the motorized cultivator can be stopped on an incline at an angle of up to 20.

(2) Adjustment method: pull the brake / clutch handle to the "off" position, adjust the length of the brake rod and the position of the adjusting nut 6 by turning it until the pressure spring 5 and the pull-out loop 3 start to touch, applying a certain pressure with spring compression. Then tighten the adjusting nut 6 and, pulling the handle to the "braking" position, check the operation of the brake.

After adjusting, check that the brake is working reliably, which can be done as follows: stop the motorized cultivator on a slope or incline at an angle of 20, move the brake / clutch lever to the “braking” position and push the implement down the incline. If the drive wheel only slides but does not roll, this indicates that the adjustment is correct and that the brake is working reliably.

~ 18 ~ Fig. 13 Lubrication of the gear coupling

Note:

(1) Keep the oil filler neck and grease fittings clean by regularly cleaning them from dirt and dust.

(2) Change the lubricant in the transmission only after the motorized cultivator is in the park position, completely draining the oil while it is still hot.

(3) Fill in enough diesel fuel through the filler neck to flush the transmission, then add new lubricant.

Oil: 15W40 - in summer, 5W30 - in winter time Liquid lubricant: TAD 17.

Grease: Texaco Multifak ep 0/00 multipurpose semi-fluid grease or synthetic calcium grease no. 2 (SYB 1409-75).

III. Long-term storage (1) Wash off dust, dirt and oil residues from the outside of the motorized cultivator.

(2) Drain fuel, oil, oil and coolant.

(3) Loosen the V-belts.

(4) Move the clutch brake handle to the "on" position and the shift lever to neutral.

(5) Cover the metal surfaces of the unpainted control levers.

(6) Using a jack, raise the motorized cultivator so that the wheels are off the ground, or inflate the tires (to a pressure of 200 kPa). Choose a well-ventilated, dry and clean area for storage.

The modern choice of motoblocks allows you to find the ideal option - from a small unit, with the help of which even a weak elderly woman will gently plow the land in a greenhouse, to a powerful mini-tractor with a cart and a plow. When looking for a walk-behind tractor, it is important to take into account all factors: engine power, gearbox and ignition system, weight, depth and width of cultivation, type of wheels and hitch. Models from the Profi company are considered one of the most versatile, both in terms of the possibilities of the canopy of additional equipment and in terms of technical characteristics.

About the manufacturer Profi

The homeland of the Profi brand is Germany, the SHTENLI ™ GMBH company. The production itself is located mainly in China. All technical processes, from the selection of materials to assembly and testing, are carried out under the strict supervision of the parent organization.

The engine is assembled under the license of the Japanese concern Honda, in compliance with all international standards. All systems comply with CE, EU, EPA, CARB standards, differ low level vibration and exhaust, tested in northern climates.

When developing the design of Profi walk-behind tractors, the manufacturer took into account the peculiarities of agricultural technology in the European part of Russia, central regions, Siberia, as well as the CIS countries. V lineup there is equipment for the processing of virgin, alumina, sandy and stony soils.

The universal hitch allows you to use potato diggers, potato planters, plows, cutters, harrows, tines, motor pumps, snow blowers, lawn crechers, brushes, mowers and other attachments.

What to look for when choosing a walk-behind tractor

• PTO. In cultivators without a shaft, the soil is processed using milling cutters, in walk-behind tractors, active equipment is hung on a special hitch, such devices are much more versatile.

• Engine's type. To work on household plots you can purchase a model with electric motor, with operation from the mains or battery. They weigh less, work quieter, do not require an oil change. Gasoline 4-stroke is more powerful, more convenient to operate, suitable for operation at low temperatures.
• Diesel engines are considered the most reliable and powerful, although they are more noisy and overall.
• Transmission. Determines the movement capabilities of the device. Most Profi models have a two-speed manual transmission and an additional rear one. A large number of gearboxes and an automatic transmission are needed mainly by those who use a walk-behind tractor with a cart as a vehicle.
• Engine power. One of the main parameters that determines the capabilities of the equipment. Cultivators for 1-5 HP suitable for processing small areas, differ in small width and depth of plowing.
• Motoblock Profi Motors 6-15 hp allows you to cultivate several hectares, copes with heavy soils, a phased development of virgin lands is possible. 18-24 hp models in fact, they are mini tractors, with their help you can process up to 1.2 meters of land, transport up to 1-1.5 tons of cargo (we also recommend that you read the article about a Subaru engine for a walk-behind tractor).

• Cooling system. V simple models the engine is cooled by means of fins on the body; these are low-speed and not too powerful options.
• The more efficient ones have forced air fans.
• Almost all Profi models are equipped with liquid radiator cooling systems.
• Equipment weight. Depends on the thickness of the metal used, the material of the wheels, the type of engine and gearbox.
• Heavier walk-behind tractors allow you to plow deeper, more stable on the road (especially when used with a cart), but the lungs do not burrow into the ground, it is more convenient for transportation.
• To increase the weight of the walk-behind tractor, you can purchase special removable weighting materials or use home-made devices made of steel or cast iron.
• Headlights. Allow you to work at night.
• Possibility of installing active or passive equipment. If the walk-behind tractor is equipped with a power take-off shaft (PTO), then attachments with moving parts can be connected to it. The PTO system can be spline or pulley-belt.
• In simple models and cultivators, it is possible to work only with rigidly fixed elements.

Unlike the Profi 1800 walk-behind tractor, the 1600 model is equipped with an inverter for a quick change of direction, this optimal choice for work in the field. The handle is height adjustable, an effective anti-vibration system is built in, and fenders and a roof are provided for splash protection.

Motoblocks Profi 16 l are equipped with a power take-off shaft, so they can be used to work with mechanical attachments - generators, pumps, cleaner high pressure, motor pump, etc.

Tillers are supplied fully assembled. However, it should be noted that the steering wheel is folded down to reduce the space required. It must be straightened, adjusted in height, and in some models horizontally, and fixed in the desired position.

Sometimes the question arises of how to assemble the Profi 1030 walk-behind tractor and some other models, since the wheels in it during delivery are at a minimum distance. In this case, loosen the fasteners, push them apart to the desired distance and fasten. The exact information is indicated in the assembly instructions for the Profi 1030 walk-behind tractor.

After factory assembly and during transportation, bolts, nuts, frame clamps may not be tightened too tightly. All hardware of the frame, gearbox housing, chassis and handle must be tightened to the stop.

You should also check and adjust the tension of the V-belt, make sure that the tire pressure is correct.

Assembling the Profi 1800 walk-behind tractor differs in that active differentials are installed on the chassis, which block one or another wheel and make the turn easier.

When driving in a straight line, for example, plowing long rows, this function only interferes, so it should be blocked before starting the movement.

Service instructions

Answers to all questions on adjustment and operation can be found in the instructions for the maintenance of motor-blocks Profi, Sadko, Don, Hooter, Plowman, Champion, Carver, Huskvarna, Lifan 6.5. They are combined into general recommendations for similar models - separately for diesel PR 840E and PR1040E, for small Hercules and Jupiter, etc.

However, some common problems are worth explaining in more detail.

What kind of oil to fill?

Before starting work, you must fill in:

• oil in the crankcase;
• oil in the gearbox housing;
• oil in the air filter tank;
• gasoline AI 92 or diesel fuel, depending on the engine system.

Make sure that there are no children, pets or foreign objects nearby before switching on.

When deciding which oil to fill, take into account the country of manufacture of the engines. Since these are Honda-licensed engines that fully comply with Japanese standards, oil of the SL / SM / SJ grade should be used. The manufacturer himself recommends proprietary formulations of Honda or Mobil 1.

Experience of use suggests that constant use of Castrol and Shell gives a high percentage of waste, while Chevron, Eneos leave a varnish film over time.

Oils of Russian manufacturers are even less compatible with Honda engines, they give heavy fumes and deposits. Nevertheless, with rare seasonal use, it is quite possible to fill in such compositions, remembering to change it in time, cleaning the filter mesh.

For winter operation, it is important to use special oils with a low viscosity index. The coolant must be completely drained in frosty conditions.

Gearbox adjustment and repair

In the model range of Profi there are walk-behind tractors with one, three and eight speeds. The first and second speeds are used for cultivation in the field, including virgin and hard soils. The fourth, fifth, sixth are needed to work on soft ground or when using the equipment as a tractor.

So, a pro 18 liter walk-behind tractor is capable of driving along the highway at a speed of 12 km / h. Do not start the engine immediately in high gear. First you need to turn on low, idle, add gas, disengage the clutch and only then change the speed.

To avoid repairing the gearbox of the Profi, Cayman, Patriot, Texas, Foreman, Krosser, Viking, Forza motoblocks, it is important to clean it and replace the lubricant in a timely manner. Add oil until it flows over the edge of the filler neck (located on the steering shaft).

According to the operating instructions for the pro 1800, 1600 walk-behind tractor and other models, the lubrication frequency should be at least every 30 hours of operation, and complete replacement and cleaning after 600 hours.

Connecting active and passive equipment - how to assemble

Connectivity depends on the pre-installed power take-off (PTO) and hitch type. The power take-off shaft transfers rotary motion from the engine to the device, converting it into the desired effect.

For example, this is how active soil cutters, planters, seeders, potato pickers, sprinklers, pumps, etc. are connected. In simple models, there is no such device, so only passive equipment can be installed - hillers, weeding machines, plows, harrows, etc.

When connecting, it is important to pay attention to the type of fixing system. The pre-installed system allows you to install only some types of equipment, and for the rest, the hitch will have to be purchased separately.

The universal hitch to the Profi walk-behind tractor makes it possible to supply not only attachments of this brand, but also devices from other companies. Models with the ability to adjust the angle of attack, position, tilt, and the degree of ejection are especially convenient.

By the type of connection, the following types of attachments are distinguished:

• Stationary, which is rigidly fixed to the frame or adapter. Powered by pull or weight of the device
• Axial, mounted on an axle, which transmits torque.
• Activator, works due to the drive from the power unit.
• Trailed, represents carts and trailers.

Plow

It is a steel plate bent at an angle to the ground. To install it, you need to remove the adjusting screw from the hitch, insert the device and select the desired height. After choosing a position, adjust its position: the rudder should be in the center of the screw, and the plow heels should be parallel to the ground.

The plowing depth for the first time is no more than 15-20 cm, if the device allows it, it will be possible to increase it in the future.

Harrow

It is carried out in the form of a steel grate with vertical pins or discs, which, when moving with a drag, level the ground, break up large clods. Installed similarly to a plow. The adjustment consists mainly in making the unit heavier, since the efficiency of the work largely depends on its weight.

Axle harrows are mounted on the wheel axle and work due to its torsion.

Tiller

With the help of such a device, you can scoop up the earth into the beds, it can be disk or wing type. It also locks onto the hitch, after which the depth and dive angle parameters are adjusted. In this case, the stand must be vertical.

The angle of rotation ensures that the ridges are covered with earth, and the distance between the lower points of the discs corresponded to the width of the row spacings.

Fan-type potato diggers are connected to the walk-behind tractor using a rigid hitch and work due to the weight of the device. It is important that there is no backlash at the place of fixation. The vibration is connected to the rear keyed power take-off shaft using a shim and a belt.

Thanks to the rocking device, the potatoes are sifted from the ground in it. Such units are suitable only for enough powerful walk-behind tractors, for example, the device of the profi 1030 walk-behind tractor with the gx2701 engine even allows it to be supplemented with a leading knife when working on heavy soils.

Blade knife

Looks like a miniature copy of a bulldozer, used for pushing bulk materials or snow. It is fixed to the supporting frame of the walk-behind tractor for fastening the pushers.

Cultivators and cutters

Refers to axial devices. When attaching the cutter, it is important not to confuse the direction of sharpening of the knives - it should look towards the cultivated soil, counterclockwise. For fixing, a stopper is installed on the output shaft.

As a rule, cutters do not require additional sharpening, since they are sharpened independently in the process. Installing cutters and cultivators is a difficult task for one person, so assembly assistance may be needed, as well as wooden trestles on which the walk-behind tractor can be installed before removing the wheels.

Lugs and tilling wheels

Installed instead of rubber wheels for additional soil treatment or to improve movement on wet soil or arable land. For weight, they sometimes have hollow drums that can be filled with sand or water.

Active potato digger - instruction manual

Installed only if there is a power take-off shaft on the walk-behind tractor. The cutter moves deeper into the ground, the soil with the tubers falls on the grate, the soil is sifted out with the help of vibration.

Rotary mower device

Connected to the PTO shaft, the transmission transmits power to the discs that rotate and cut the stalks of the grass. Depending on the design, it can be attached to the front, rear or side of the walk-behind tractor, like a trailer or a canopy.

Segment trimmer of the Profi walk-behind tractor

Suitable for mowing lawns or haymaking. A connecting rod is supplied to the movable element, which creates forward-reciprocating movements, and the connecting rod, in turn, is connected to the drive through wheels and pulleys.

In addition to the listed units, on motoblocks with a power take-off shaft, you can install a wood splitter, sprayers, aerators, multi-row vacuum seeders, flat cutters, communal hinges, hydraulic pumps, a brush drum, a snow blower and other devices.

You can clarify the connection methods and settings for them in the attached instructions.

When buying a unit, you must make sure that it is compatible with this model of the walk-behind tractor.

A huge number of different attachments and attachments make the Profi walk-behind tractor indispensable in the household. When choosing, it is important to think in advance about the scope of work and those units that will be acquired over time or immediately.

The main advantages of motoblocks of this brand are a reliable Japanese engine, an anti-vibration system that prevents shaking and damage to the chassis, as well as build quality.
