Which engine for a walk-behind tractor to choose to replace a faulty model: we tell in detail

Views

The main distinguishing factor of the models is the design of the engine and its performance. All other details are almost the same.

The engineering plant cooperates with world leaders in the production of powertrains, among which brands such as Subaru, Honda, Lifan, Lianlong, Hammerman and Briggs & Stratton can be distinguished. These brands produce reliable products that run on a variety of fuels. Depending on this parameter, the walk-behind tractor is gasoline or diesel.

  • Gasoline engines are especially popular because they are affordable.
  • Diesel devices are more reliable and have a large motor resource.

Today the plant produces several Agat models.

"Salute 5". It is based on the Japanese engine of the Honda GX200 OHV brand with forced air cooling, what protects him from overheating, therefore, increases the service life. Powered by gasoline, manually started by means of a starter. Technical characteristics are standard: power - up to 6.5 liters. with., the depth of tillage - up to 30 cm, the volume of the fuel tank - about 3.6 liters.

"BS-1". The standard version of the middle class is designed for the processing of small land plots. The unit is equipped with an American Briggs & Stratton Vanguard 13H3 gasoline engine with electronic ignition. Among the technical characteristics, one can note the power (6.5 liters. From.), The volume of the tank (4 liters) and the depth of plowing of the earth (up to 25 cm). A distinctive feature is an automatic transmission and the presence of adjustment of the steering levers in two planes.

Model "BS-5.5". This modification also has a US-made Briggs & Stratton RS engine. Compared to the previous device, it is less powerful (5.5 hp), otherwise the characteristics are similar. The device runs on gasoline.

"KMD-6.5". The motorized apparatus is equipped with an air-cooled Hammerman diesel engine, which allows it to work efficiently even under heavy load. The unit is characterized by economical fuel consumption. The main drawback is its inability to adapt to the conditions of the northern regions of the country, since at low temperatures there are problems with starting.

ZH-6.5. This is one of the latest modifications of the Agat brand. The Zongshen engine is modeled after the Honda GX200 type Q.

X. The cultivator is equipped with a power unit of Japanese origin Honda QHE4, the capacity of which is 5 liters. with. It is lighter and more maneuverable, due to the installation of a less capacious fuel tank of 1.8 liters.

"L-6.5". Motoblock based on the Chinese Lifan engine. It can be used to work on an area of ​​up to 50 acres. Gasoline is used as fuel. The unit is started manually, there is protection against overheating, the depth is up to 25 cm. The unit is adapted to winter conditions.

"R-6". The technical device is equipped with a Japanese-made Subaru four-stroke petrol unit. The motoblock is considered one of the most powerful in the lineup - it has a rated power of up to 7 horsepower. Among the advantages is regulated management.

Motoblocks "Agat", depending on the attached accessories, can perform various functions. Below are just a few examples.

  • Snow blower.
  • Garbage collector.
  • Mower. With the Zarya rotary mower, you can cut not only weeds, but also rough-stemmed plants such as ears or straw.
  • Potato digger and potato planter. Such an aggregate can be obtained using additional attachments, which make it possible to simplify the procedures for planting and digging out potatoes, as well as other root crops.
  • Hillers. Equipment is required on farms to mechanize the manual labor of weeding and hilling the beds. It is also effective for “cutting” an area into beds.

Terms of use

It may seem that the most important thing is buying and installing a new motor. But this is not true

In order for a walk-behind tractor with a new "heart" to last longer, you need to follow the instructions and take care of it during use.

Therefore, the first thing to do before buying is to consult with an expert regarding the specifics of using the product. In addition, it is necessary to familiarize yourself with the instructions for installation and operation. This will avoid mistakes.

Attention! It is necessary to constantly engage in preventive measures - change oils and clean the structure.

In the case when it was noticed that the engine operation is unstable, you need to contact the service center. In this case, the warranty card may be by the way. The reasons for the malfunction may be different, so if you do not have special knowledge, you should not disassemble the engine yourself. When examining the device, an expert will immediately tell you what needs to be fixed. The problem may be in the oil seal, improper fuel, etc.

Chinese motoblocks with PTO

It just so happened that all Chinese equipment is distinguished primarily by its low price, and it is the price that is considered the main reason for buying this equipment. It is good if such a price is due to mass production and a wide range of products, but some Chinese manufacturers are going to reduce the cost by using low-quality raw materials and cheap, low-quality components. And coupled with a poor build, such a device may not live up to the end of its warranty period or "die" just when the warranty has just expired

So when buying Chinese motoblocks, carefully study not the characteristics and price, although this is also important, but the reviews of real buyers, see the type of their work, in general, approach the questions with full responsibility. It's your money

Engines made in China

Chinese motors for motoblocks are most common on budget equipment and can differ significantly in quality.

Chinese motor

If the units of large manufacturers (Lifan, Zongshen) copied from the Honda GX are close to the Japanese original in quality and resource, then the cheaper ones, often not even labeled by the manufacturer, still retain the famous lottery “Chinese quality”.

Consider the most common types of engines (since the same motor can be produced by a dozen companies, it makes no sense to distinguish Chinese engines by brand in this regard):

160F

The smallest (4 hp) engine for light motoblocks and cultivators. The model for its creation was the Honda GX120 engine.

It is also the cheapest Chinese motor - it costs no more than 5-6 thousand rubles.

168F

Most popular engine model copied from Honda GX160. It is a 5.5 horsepower petrol engine with a displacement of 163 cm3.

Due to its simple and reliable design, this motor can be found on walk-behind tractors, cultivators, gas generators, motor pumps and many other units with gasoline engines.

This motor can only be started with a recoil starter. The gas distribution system - OHV, thanks to the successful layout, setting the valve clearances is very simple and quick. The engine can be additionally equipped with an oil level sensor and a generator light coil.

Produced by almost all Chinese factories: Lifan, Zongshen, Loncin, and so on. The price can range from 5 to 9 thousand rubles, both depending on the manufacturer and on additional equipment: a reduction gear, an oil level sensor, and so on. The Lifan engine is installed on the Krot, Lifan, Oka walk-behind tractor.

Zongshen

168F-1, 168F-2

A more powerful variant of the 168F engine, a copy of the Honda GX200. Thanks to the volume increased to 196 cm3, it develops 6.5 hp. Otherwise, it is a complete analogue of the 168F motor.

The price is slightly more expensive, depending on the manufacturer, it can be 8-10 thousand.

170F

Seven-horsepower variant of the 168F engine, which has no direct analogue in the Honda GX family. The displacement is 212 cm3 (in fact, this is a slightly bored 168F-1 motor). The piston from this motor can be used when repairing a 6.5 hp engine, since the manufacturer does not provide for repair dimensions.

The thickness of the cast iron sleeve on most Chinese motors allows this.

The price range is the same - from 8 to 10 thousand rubles.

177F

A fairly powerful (9 hp) gasoline engine, which can be found on heavy walk-behind tractors and mini tractors. Copied from Honda GX270.

Price - from 15 to 18 thousand.

182F

An eleven-horsepower engine with a displacement of 340 cm3, an analogue of the Honda GX340. In the line of most manufacturers of engines for motoblocks, this is the most powerful engine produced.

The price is from 17 to 19 thousand rubles.

170F (A), 170FE, 170FS

A diesel engine for a walk-behind tractor, the price of which, depending on the configuration, is 26-34 thousand rubles. The working volume of these motors is 211 cm3, the developed power is in the region of 4 horsepower. Thanks to the lubrication of the crankshaft under pressure, these engines have a significantly higher resource than gasoline ones, although they are significantly more expensive.

The letter E in the model designation (like in Chinese gasoline engines) means the presence of an electric starter and, accordingly, a 12-volt generator coil.

How to install a Lifan engine on a walk-behind tractor

Each model and class of walk-behind tractor has its own engine. Consider these examples:

Motobloku Ugra NMB-1Н7 with Lifan engine according to technical characteristics corresponds to version 168F-2А.

Motobloku Salyut 100 - version 168F-2B.

Ugra NMB-1N14 middle class - Lifan 177F engine with a power of 9 liters. with.

Agat equipment with a Lifan engine can be equipped with the 168F-2 and Lifan 177F models.


An eye with a Lifan 177F engine when aggregated with attachments will work better and more efficiently. Model 168F-2 with a capacity of 6.5 liters. with. also suitable for the Oka MB-1D1M10S walk-behind tractor with the Lifan engine

The engine can be installed on motoblocks Ural, Oka, Neva according to the following algorithm of actions:

  1. Remove the protective cover from the old engine, belts, pulley, while unscrewing the bolts.
  2. Remove the air-purifying filter to disconnect the throttle cable.
  3. Remove the engine from the walk-behind tractor frame.
  4. Install the motor. If necessary, a transition platform is installed.
  5. A pulley is attached to the shaft, the belt is pulled for better track performance, adjusting the position of the motor.
  6. Secure the transition platform and engine.

The user must take care of the mounting hardware when installing the motor.

Motoblock Cascade

When installing an imported Lifan engine on a domestic walk-behind tractor Cascade, the following additional parts are needed:

  • pulley;
  • transition platform;
  • adapter washer;
  • throttle cable;
  • crankshaft bolt;
  • fasteners.

The mounting holes on the frame are not aligned. For this purpose, a transition site is being acquired.

The cascade is equipped with a domestic engine DM-68 with a capacity of 6 liters. with. When replacing the motor with Lifan, choose the 168F-2 model.

Motoblock Mole

When installing the Lifan engine on the Mole walk-behind tractor, equipped with an old domestic engine, when replacing, it is necessary to have installation kits, which include such elements as:

  • pulley;
  • adapter washer;
  • throttle cable;
  • crankshaft bolt.

If there was an imported motor on the walk-behind tractor, then only the Lifan engine itself with an output shaft diameter of 20 mm was enough to install it.
