Before first use

The GT 700 SK needs regular break-in at partial load. Not everyone will want to carry out this procedure often, but it is very useful for running-in and adapting parts to local weather conditions. In this regard, the running-in should be performed at least once, namely immediately after purchase, or before the first use of the walk-behind tractor. Running in requires basic steps. Let's consider them step by step:

We start the engine, let it idle for 40 minutes
Checking the gearshift mechanism

It is important that the box operates without noise or vibration. They are unacceptable, since the walk-behind tractor is completely new.

Otherwise, the car must be replaced with another one, or a return must be made within 14 days in accordance with the law "On the protection of consumer rights".
After making sure that all the bolts are securely fastened, as well as that there are no oil smudges in the lower part, you can start operating the walk-behind tractor. In this case, soil processing is allowed in various ways, including harrowing, hilling, plowing, planting and digging vegetables, transporting goods and other types of work. The main thing is that the load on the walk-behind tractor does not exceed 50% of the maximum load, otherwise there will be more harm than benefit from running in
The run-in lasts 7-8 hours - this is enough for the internal components of the walk-behind tractor to adapt well to weather conditions. Then you can start the maintenance of the machine.
The next day, the walk-behind tractor is ready for full operation, it can be subjected to 100 percent load according to the instructions.

Maintenance and operation

Before starting work, it is necessary to run in. In the process of all the manipulations, the foreman's engine receives the necessary lubrication, and the parts rub against each other.

Run-in is carried out for 3-4 hours when operating at 50% of the unit's capacity. After running-in, it is necessary to drain the used oil and refill with new one.

As you use the unit, set aside time for maintenance, which involves a number of steps:

• Check the oil and fuel level before operation (the manufacturer recommends using gasoline with an octane rating of 92 and SAE 15W40 oil).
• Make sure all bolts are secure.
• Check drive belt tension and tire pressures.
• In case of detecting extraneous sounds of a running engine, conduct a detailed inspection and repair.

The maintenance work schedule is presented in the user manual.

1. The oil should be changed every 25 hours of Prorab operation.
2. In the transmission, the oil must be changed after 100 operating hours.
3. Control levers must be lubricated with Litol or Solidol once a month for their smooth operation.
4. Storage of the Prorab GT 715 SK walk-behind tractor

In order for the walk-behind tractor to work without breakdowns, it is necessary to operate it correctly and also store it correctly.

Adhering to the following rules, you will provide the unit with reliable storage, and yourself a reliable assistant for many years:

• All oil and fuel must be drained before storage.
• Wash the walk-behind tractor and wipe off all dirt build-up.
• Coat all metal parts with a thin layer of lubricant.
• Close the inlet and outlet valves.
• Cover the unit with a tight cover and store in a dry, ventilated area.

Attachments

For the successful operation of mounted mechanisms with a motor-cultivator, a rational choice should be made so as not to increase the load on the engine and not to worsen the quality of work. Light, low-power models of Prorab cultivators are not able to work with additional mounted implements, their functionality is limited to loosening and light plowing of the soil.

Motor-cultivator Superintendent 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 milling cutters. Thanks to this, the owners have the opportunity to choose the optimal models of the foreman cultivators, necessary for the cultivation of certain crops, for the performance of special work.

Foreman cultivators with 6.5 hp gasoline engines. and above successfully cope with a number of tasks - they easily plow virgin soil, are used in a set with a two-row plow, a wide harrow, a potato digger.

The hiller works efficiently in aggregation with the Prorab GT 732 SK cultivator when hilling potatoes and other tuberous plants. The single-row plow will perform deep plowing of the soil. The pump is used to pump water, and pumping units are used for irrigation. With a harrow, it is convenient to cut furrows, prepare beds.

Planting potatoes with a motor cultivator Superintendent GT 71 SK:

On powerful models, adapters are allowed to facilitate work. With the help of a universal hitch, a trolley for transporting goods is connected. Metal wheels with grousers and weighting agents will provide the Prorab cultivator with good cross-country ability on difficult terrain. Brushes, shovels, plows, and other accessories will greatly expand the options for your cultivator.

It also increases functionality when using mowers, potato planters and hillers, and in winter, a snow blower and tracks.

Maintenance of the walk-behind tractor Foreman GT-732 SK

The manufacturer, according to the instructions, recommends using AI-92 gasoline, SAE 10W30 class engine oil for the Prorab walk-behind tractor, and SAE 80W90 oil for the transmission. Clutch bearings, an expanding bracket, and other structural elements that require lubrication are treated in accordance with the manufacturer's instructions with machine oil, water-repellent lubricants Solidol, Litol or analogs.
