Features of Weima walk-behind tractors

Weima walk-behind tractors are products of the Chinese company Chongqing Weima Power Machine Co. Ltd. The company specializes in the development of agricultural machinery and modern engines.

Thanks to the improvement of Chinese products, the popularity of Weima walk-behind tractors is increasing. They are shipped to various countries around the world. At an affordable cost, Weima walk-behind tractors are reliable and durable.

A variety of types allows you to choose a product for both owners of large land plots and private owners with smaller plots. The best options for the former are powerful diesel units. They can withstand serious stress. Gasoline motoblocks with a differential, a low gear are suitable for processing 5-20 acres of land.

The units are characterized by removable motor parts that can be repaired.

The motor resource of Weima motors is quite large, which is also proven by the products of other enterprises to which parts are supplied (for example, the Belarusian MTZ). For a long service life, it is sufficient to change the oil on time and control the contamination of the filters. The features of this part are most appreciated by farmers.

It is arranged in this way. that the walk-behind tractor does not stall even with strong dust concentrations. Correct valve clearances are sufficient for the engine itself for a long service life. They are inlet or outlet. Products affect the consumption of the combustible mixture, the "noise" of the device. Correct adjustment will greatly increase the engine life.

The main advantage of Chinese motoblocks is their light weight. Even with hinges, heavy motor vehicles barely reach a weight of 100 kg. The units are characterized by high performance. Users note the efficiency and convenience of the units. The layout of the device is similar to the models of other Chinese companies. When repairs are needed, it is very easy to find inexpensive spare parts.

For some, the light weight of powerful motoblocks is also a disadvantage. When attaching standard cutters, the engine does not cope - it fires and does not start. Attachments are supplied by a Chinese manufacturer in an incomplete set.

For example, you have to buy guide discs yourself. Due to their absence, the walk-behind tractor is difficult to control. In the production of some parts, the manufacturer uses not quite high-quality material. For example, the coulter breaks on the ground almost immediately. Since the mechanism of the part is simple, it is simply replaced with a homemade device.

Chinese equipment is distinguished by good performance and a variety of model range. Consider the company's popular products.

PTO shaft diameter 13/8 Z6. The device is standard for mounted parts of middle class equipment. The mass of the walk-behind tractor is 160 kg, the cost is about 90 thousand rubles.

The units belong to the heavy class, suitable for processing plots of 1 hectare. The engine of the device can consume both gasoline and diesel. Increased loads are not terrible for the walk-behind tractor thanks to the worm gear. The gearbox has 4 forward and 2 reverse speeds.

Motor vehicles are capable of processing any kind of soil with a 1 m strip, consuming about three liters of fuel. The possibility of hitching with a large number of attachments will provide a wide functionality of the device.

Product with an engine power of about 5 HP. with. refers to light motoblocks. The power unit is single-cylinder, four-stroke with a tank volume of 3.6 liters. The machine is equipped with an electric start with forced air cooling. Complete cutter length 40 cm.

To navigate the choice of a walk-behind tractor, you need to compare:

• its weight;
• way of rotation of cutters;
• engine power.

These features make it possible to subdivide the models into three types.

• Lungs. They are popular with owners of 20 acres of vegetable gardens. The units are compact, and their device is easy to maintain. Most models are equipped with a two-stroke engine with a pair of cutters. They cope with the processing of light soils with a working width of 30 to 90 cm. Lightweight walk-behind tractors are also equipped with four-stroke engines.
• Medium motoblocks are distinguished by the ability to switch speeds, weighing up to 100 kg. The technical characteristics of the products allow you to work hard soils, large areas. The functionality of the machine has been expanded with additional attachments.
• Heavy motoblocks differ in engine power up to 16 liters. with., which allows you to cope with overgrown areas and heavy soils. In addition to the milling cutter, the basic equipment includes a harrow, a plow, a mower, and a snow blower. In fact, the products are mini-tractors.

Maintenance of the walk-behind tractor consists in organizing a number of actions that will ensure reliability and safety.

This is a mandatory maintenance component for the unit. The instruction implies an annual adjustment, and in case of a breakdown, the valve seats need to be removed more often. In the process, optimal clearances are established. The permissible dimensions between the sockets of the inlet valve are 0.10-0.15 mm, that of the outlet valve is 0.15-0.20 mm. The inlet valve is located near the filter, and the outlet valve is near the muffler. The interval is checked with a feeler gauge, the permissible distances are adjusted with a screwdriver and a wrench.

The first procedure is carried out after 2-5 hours, then after a day of constant movement of the apparatus. It is better if the engine is warm during replacement, which will affect the viscosity of the oils.

Prevention includes checking the ignition and fueling. The main work is connected with checking candles. If you remove the cap, you can see carbon deposits, which can be cleaned, and if damaged, the part is replaced.

The fuel supply system includes filters, with contamination of which malfunctions occur in the engine. The fuel filter in the tank is cleaned, and the air filter in the carburetor is cleaned or replaced with a new one.

Actions are reduced to finding and eliminating damages and defects. It is also necessary to maintain pressure in the range of 1-2 kgf / cm2. It is worth remembering that both high and low pressure are harmful for pneumatic tires. The tread is responsible for the greatest tractive effort of the wheel. The arrows show the correct direction, they are on the sides of the wheels.

To properly mill the earth with a diesel walk-behind tractor, you need to take into account a number of nuances.

It is better to carry out work, if in autumn, then after harvesting, so that the field is plowed with a plow. Without additional plowing of the site, the land will be dense, the load on the walk-behind tractor will increase.

When plowing, the transport wheels of the walk-behind tractor are replaced with a set of cutters. The working part of the knives must be sharpened. Otherwise, the device will not move forward, but only bury itself in the ground.

The plowing depth is regulated by the coulter. This is a bar installed at the back of the machine. The recommended mounting method is the second hole from the bottom of the part. With this installation of the opener, the depth of the cutters will be about 20 cm. If the plowing depth needs to be increased, the part is fastened through the upper holes.

From other devices of Weima walk-behind tractors, various sheds, an extension of an axle shaft, a potato planter are known. Less common is the axle shaft extension, which is needed to extend the wheelbase of the unit. The detail adds stability and removes the dependence of the machine on track width.

Extension cords solve problems:

• for the processing of heavy soils;
• uneven areas;
• when hanging complex equipment;
• with the installation of lugs.

Parts are installed on the output shafts, while the reliability of the fasteners and the tightness of fixation are strictly observed.

Of the sheds, the potato planter is popular, which differs in carrying capacity and power. The price for it varies from 5 to 20 thousand rubles. Farmers also actively use plows, harrows, mowers, and snow blowers.
