Let's consider the strengths and weaknesses of the manufactured equipment, as well as the available options for modernizing the design.

Features of application

The manufacturer recommends using 92 octane gasoline and SAE 15W40 oil for the Foreman GT 709 SK walk-behind tractor.
The lubricant should be replaced according to the schedule given in the instructions.

The first replacement is carried out after running-in, which is carried out immediately after purchase or after a long period of inactivity.

The break-in itself does not take much time. By adhering to the following steps, you will be able to properly run-in, thereby ensuring that all parts are ground in:

1. Check the oil and fuel levels in the tanks. If a shortage is detected, it is necessary to top up.
2. During the first 4 hours, the engine should run at idle speed. But it is impossible to work for more than 20 minutes, so it is necessary to carry out programming, increasing the speed for a short time to the maximum.
3. For the next 4 hours, the cultivator can be used, but load no more than 50% of its full capacity.
4. Upon completion of the break-in, drain the used oil and fill with new oil.

The schedule for maintenance work is presented in the user manual.

• The oil should be changed every 25 hours of operation of the device.
• The transmission oil must be changed after 100 operating hours.
• Control levers must be lubricated with Litol or Solidol once a month for their smooth operation.
• After the end of the work season, the Foreman GT 709 SK walk-behind tractor must be preserved, namely: cleaned of dirt, wiped dry, drained fuel and oil, lubricated the working parts, covered with a cloth and left in a dry place until work is resumed.

User manual

The operating instructions recommend using the walk-behind tractor for processing medium and heavy soils.

When raising virgin soil, it is necessary to take breaks to cool down the power plant.

The product manual regulates the following rules for its use:

• Run-in. This procedure is carried out immediately after purchase or before the first entry into the field. First, the correct gear shift is checked, then the engine is cranked by hand. Then the engine starts and idles for 40-60 minutes. Then, for 12 hours, the product is loaded at half the rated power.
• Before each visit to the site and after completion of work, a control inspection is carried out. The appearance of the machine is checked for mechanical damage. The chassis and cooling system are cleaned of dirt. If necessary, add or replace oil.
• After every hour of operation it is necessary to stop and turn off the walk-behind tractor. When lifting virgin soil or transporting heavy loads, technological breaks should be taken after 20-30 minutes. Overheating the engine can cause costly damage.
• If the unit is not planned to be used in winter, then it is preserved. The spark plug is unscrewed, oil is poured into the cylinder, and the hole is closed with a rag. All metal parts are coated with thick lubricant. The product is covered with thick material to protect it from ultraviolet radiation and dust.

You can store the walk-behind tractor outdoors under a canopy or in a dry, ventilated shed.

In addition, the model range of Prorab cultivators has special design and technological specifics - many different machine options have been developed with a varied combination of basic soil cultivation parameters: working width / tillage depth. Therefore, focusing on these indicators, each owner will be able to choose the most optimal model for himself, based on the characteristics of the soil being processed, the type of crops grown, and other needs.

Attachments

To successfully operate mounted mechanisms with a motor cultivator, you should make a rational choice so as not to increase the load on the engine and not to deteriorate the quality of work. Lightweight, low-power models of Prorab cultivators are not capable of working with additional mounted implements; their functionality is limited to loosening and light plowing of the soil.

Motor cultivator Foreman GT 71 SK works with attachments:

Unlike other brands, TM Prorab offers many different options for combining the “width/depth” parameters when processing soil with cutters. Thanks to this, owners have the opportunity to choose the optimal models of Foreman cultivators necessary for growing certain crops and performing special work.

Cultivators Foreman with 6.5 hp gasoline engines. and above successfully cope with a number of tasks - they plow virgin soil with ease, and are used in conjunction with a double-row plow, a wide harrow, and a potato digger.

Attachments

The Prorab company has launched the production of attachments for motor cultivators, which are presented in a huge assortment. Hiller. This device is especially popular among owners of potato fields. With its help, you can remove weeds and hill up potato rows, while forming high and neat ridges. A potato digger and potato planter are also often used by summer residents when planting and harvesting potatoes. The devices greatly facilitate the heavy physical labor that is usually associated with growing this crop.

The cutters are designed for loosening the soil, removing weeds and cultivating virgin lands. For motor cultivators, saber-shaped models are mainly used, although for powerful samples the use of “crow’s feet” is allowed. The adapter is a metal frame with a seat and is designed to allow the operator to operate the cultivator while sitting. This function can be very useful when transporting goods and when processing large areas. The mower is designed for preparing feed for cattle, removing weeds and mowing lawns.

A single-row plow allows you to plow virgin lands and is capable of penetrating 25-30 cm deep into the soil. For more powerful plows, the use of double-row options is allowed. The harrow is used to level the land when preparing it for sowing or wintering. A pump is necessary for pumping or transferring liquids and is often used in combination with sprinklers for watering plantations.

However, when choosing a motor cultivator, it should be taken into account that most of the attachments listed above can be used with models with a power of over 6 hp. With. This applies to the plow, adapter and cart. Therefore, before purchasing a motor cultivator, it is necessary to determine the volume and type of work, and only after that choose both the unit itself and the attachments.

Service

The GT-715 SK foreman consumes AI-92 gasoline and oil, the manufacturer recommends SAE 15W40 class. Before work, it is recommended to always check the oil and gasoline levels, test the reliability of fastenings of moving joints and bolts, check the tire pressure, and the tension of the drive belt.

Preventative work consists of timely replacement of consumables, engine oil after 25 hours of operation, transmission oil after 100 hours. Parts and assemblies that require lubrication are treated with universal water-repellent lubricants Litol and Solidol at least once a month. Before long-term storage, fuel and oil are drained, the Foreman walk-behind tractor is thoroughly cleaned of dirt, wiped dry with a rag, coated with lubricant, and the valves are closed.

Advantages and disadvantages

Like any agricultural machinery, the Prorab cultivator has both strengths and weaknesses. The advantages include economical fuel consumption, which has a positive effect on the budget, and very easy operation of the unit. The device is highly maneuverable and smooth, and the height-adjustable handles allow you to adjust it to your height. In addition, the manufacturer provides a guarantee of protection against accidental fire of the unit, which makes its use absolutely safe.

For ease of use, the cultivator is equipped with a lighting system, which allows you not to stop working after dark. Many consumers also note the convenient location of the main keys and control levers located on the handle, which makes it possible to easily switch gears, control the gas and brake. The advantages include the ability of the cultivator to work in conditions of high and low temperatures - this allows it to be used in the range from -10 to 40 degrees.

However, such units have their drawbacks. These include the low endurance of mechanisms when working with virgin soil, as well as rapid overheating of the motor when transporting loads weighing over 500 kg. To be fair, it should be noted that models of this class are not intended for particularly heavy loads, and in such cases it is better to use a walk-behind tractor.

Operating instructions for the Prorab GT 55 BT/ Prorab GT 65 BT cultivator.

Run-in

Before running the cultivator, you must check all components and connections and tighten the bolts if necessary. Next, the car is filled with fuel and lubricant. During the running-in period - duration 20 hours, all components and mechanisms are ground in and working gaps are calibrated.

When running in, the unit should not operate at maximum speed; after 2 hours of continuous operation, it is necessary to take a 15-minute break to allow the engine to cool. You should visually monitor the functioning of systems, monitor the condition of moving parts and components. Upon completion of the break-in process, the engine oil is replaced with fresh one; in the future, the engine oil is replaced after 100 operating hours.

Basic faults

Often, difficulties in the operation of Foreman cultivators arise due to violation of the recommended operating modes, the use of low-quality fuels and lubricants, and non-compliance with the preventive inspection schedule.

If the engine does not start, the reason may be:

• Lack of gasoline or oil;
• Fuel or air filters are clogged;
• Problems with the ignition system (the terminals have come off the spark plugs or carbon deposits have formed on them);
• Incorrect carburetor setting.

If the unit vibrates strongly during operation:

• Perhaps you are working with too heavy soil;
• Looseness of bolted connections of the unit itself;
• The hitch is not secured correctly;
• The drive belt has become unusable.

Sometimes when operating motor cultivators, owners are faced with the fact that the machine buries itself in the ground. This could be due to a number of reasons.

• The total weight of the cultivator with cutters does not correspond to the quality of the soil. Light machines are usually equipped with 4 heavy cutters; when working on loose soil, sinking occurs. In this case, you need to remove the outer knives from the cutters, and install a weight at the rear of the cultivator for balance.
• Switching the machine to second gear is not always appropriate when operating on loose soil. If there is a reverse, you need to use it to pull out the cultivator, or do it manually.
• Due to improper installation of cutters, the machine can also become buried. They should be reinstalled in accordance with the instructions at the appropriate angle, taking into account the direction of the knives forward.

Following the manufacturer's recommendations will help you effectively process your site and protect your equipment from premature breakdowns, searching for spare parts and costly repairs.

Sergey Vasechkin, Samara:

“Very good cultivator Foreman 55, I bought it on sale, the price is normal. I use it in spring and autumn for plowing and weeding. Our plot is small, the soil is loose, and 5.5 hp is enough power.”

Alexander:

“Cultivator foreman 65 W(t). With normal maintenance it works quite reliably. Clean the air filter and change the oil once a season. The plastic gears are hidden under the casing, I think there should be no wear. The motor runs smoothly without any strain. Among the shortcomings: the handles are not adjustable in height, a little inconvenient. And during the run-in, the spark plug immediately flew off.”

Features of service, operation

Foreman cultivators consume high-quality AI-92 gasoline and SAE 10W-30 class motor oil. The features of the device, operation, and adjustments of the motor cultivator can be found in the factory operating instructions at the link.

The following must be checked daily or every 5 hours of operation:

• fuel level in tank
• amount of engine oil
• reliability of fastenings and threaded connections
• correct assembly and connection of components
• cable tension
• presence of technical fluid leaks
• presence of lubricant in the gearbox.

Run-in, first launch

For Prorab cultivators, the break-in procedure is mandatory. Before the first start-up, check the reliability of the fastenings, the condition of all systems, components and mechanisms, and fill with fuel and engine oil. Then, for 20 hours, the cultivator is operated at reduced speeds in a gentle mode. During this period, the final grinding of parts and assemblies and calibration of the working gap takes place.

During the break-in period, it is necessary to take breaks of 15 minutes after two-hour periods of operation to cool the engine. At the end of the break-in, the air filter is cleaned and the engine oil is replaced with new one. In the future, the oil is changed after 100 hours of operation.

Basic malfunctions, repair of walk-behind tractors Foreman

Thanks to a rational, well-thought-out design, cultivators are not prone to system breakdowns and malfunctions. Problems mainly arise due to violation of the operating instructions, the use of low-quality fuel, inappropriate motor oil, and failure to comply with the maintenance schedule.

You should always remember that Foreman cultivators require frequent breaks in operation to cool down, since the motors are sensitive to overheating. It is especially important to maintain a work-rest regime under intense loads on heavy soils, otherwise repairs are inevitable.

Due to their light weight, the Foreman cultivators can bury themselves in the soil when plowing. From the experience of owners, this can happen for the following reasons:

• Incorrect installation of rototillers - you should refer to the factory instructions and reinstall the rotors correctly with the knives facing forward.
• The weight of the machine and installed cutters does not correspond to the quality of the soil. Typically, this problem is typical for lightweight models that are equipped with two pairs of cutters. In this case, the Foreman should leave one cutter on each side on the cultivator and attach a weighting agent.
• When working on soft ground, it is not advisable to operate in second gear.

• Denis, Moscow region. An excellent cultivator for little money. I've been using it for four months. Ideal for processing a summer cottage area of ​​6 acres. The unit is assembled from high-quality materials - at least there were no major breakdowns. But 4 months is a short period of time, so we’ll see how the technology behaves further. I would like to note the standard wheels, which provide good cross-country ability on off-road and muddy ground. There is support for 92 gasoline. By the way, the car consumes only 1 liter per hour. I use it 4-5 hours a day.
• Boris, Tver region. An excellent cultivator for everyday tasks. Hilling, cultivating, mowing, transporting goods - all these works with the Foreman are carried out with high efficiency, and at the same time the device is undemanding in terms of fuel quality and consumes no more than 1.5 liters per hour.
• Oleg, Nikolaev. I liked the unit. I received the GT 65 BT foreman as a gift from the work team - for good services, so to speak. We work as farmers, we have large professional walk-behind tractors, up to full-fledged tractors. And this Foreman was useful to me for housekeeping. The machine effectively cultivates, processes complex hard soils, and can also pump water. If there is a lack of power or a lack of weight, I install lugs, and the problem disappears by itself.
• Kirill, Petropavlovsk. I have a lot in common with this cultivator. I got the GT 65 BT foreman from my father. The car will be five years old in 2018, but it is still running. I service it in the garage. Unfortunately, breakdowns occur regularly. But the spare parts are cheap, otherwise I would have sold it long ago.
• Vladislav, Irkutsk. A cultivator for all occasions. I use it 8 hours a day. I have a garden of 26 acres, there is enough work. Perhaps the Foreman is working to the limit of his capabilities. I really feel it, even sometimes the engine stalls for no reason at all. But I was pleased with the consumption of 1 liter per hour.
• Dmitry, Yaroslavl. I use the GT 65 BT for transporting goods, cleaning areas and cultivating the soil by hilling, plowing, etc. The cultivator is very good for planting and digging up root crops. The engine runs almost silently, and there are almost no vibrations. But the wheels quickly become clogged with soil; they need to be cleaned regularly.
