The Agat company is a well-known Russian brand engaged in the production of fuel control equipment elements for civil and military aviation. The production of walk-behind tractors is not the main direction for this enterprise. The plant mastered the production of gardening equipment in 2002, when, by order of Salyut, it began to assemble several models of walk-behind tractors. In 2012, the companies took different paths, and from that moment on, the Gavrilov-Yamsky Machine-Building Plant has been producing equipment under its own brand.
The Agat product line includes several types of walk-behind tractors with motors from Japan, the USA and China. All of them are distinguished by significant technical characteristics and good quality. Thanks to this, the demand for Agat walk-behind tractors always remains stable.
Model Agat 6.5 Lifan
The Agat L-6.5 walk-behind tractor (Lifan 6.5 engine) is considered one of the most popular in the brand’s product line. Structurally, the model is almost a complete analogue of the Salyut 5 device. This special equipment is designed to work on medium and small areas (up to 50 acres).
Like all products of the Gavrilov-Yamsky plant, the walk-behind tractor is characterized by increased reliability. In terms of design, Agat 6.5 Lifan is a classic model with cutters installed on the drive axle in place of the wheels, and a power take-off pulley. You can work with a walk-behind tractor almost all year round, performing a huge range of operations.
A key feature of the technology is the low center of gravity. This solution greatly simplifies the work. The wheels and steering of the walk-behind tractor can be easily dismantled, which is very convenient for transportation.
The Agat L-6.5 model is based on a durable frame to which the main elements are attached. The walk-behind tractor is equipped with a 3-speed gear reducer (2 forward speeds, 1 reverse speed). Low gearing is usually used for heavy work, while high gearing is used for transporting goods. special equipment is assembled with high-quality equipment. At the same time, Russian working conditions and the realities of agriculture are taken into account. This allows the walk-behind tractor to function for a long time without breakdowns.

The device can be equipped with virtually any equipment that may be required.
Important! Thanks to the versatility of the hitch and fastenings, most home-made devices, in particular potato diggers, are suitable for the walk-behind tractor.
The use of the equipment is strictly regulated by the operating data of a specific model. Depending on the nature of the work, the equipment can perform various tasks, which makes it popular.
Run-in
Agat 6.5 Lifan special equipment requires regular maintenance and initial running-in, which is performed when purchasing a new or used device. This process is carried out in several stages:
- Refueling the walk-behind tractor and checking the oil level. If necessary, add oil.
- Start the engine and idle (no more than 15 minutes).
- Work at medium speed. At this stage, work is performed in all gears and the optimal position is selected.
- Operation with additional equipment. Checking existing devices for low power (no more than 60% of the maximum level).
After completion of the run-in, technical maintenance of the equipment is carried out.
Oil in the walk-behind tractor gearbox. self-replacement
The standard gearbox of any walk-behind tractor needs lubrication more than its factory engine. The gearbox is initially a complex structure consisting of several gears responsible for transmitting force from the motor to the working parts of agricultural machinery. During operation of the gearbox, the gears are constantly in contact with each other, which leads to the gradual wear of their teeth. To slow down this process, it is necessary to use a good-quality lubricant.
You can check the level of lubricant contained in the gearbox at a certain point in time as follows:
- Clean a 70-centimeter piece of wire that will act as a probe;
- Bend a homemade probe into an arc;
- Push the wire through the filler hole in the gearbox to the end and pull it out.
If the oil spot is located at a distance of 30 cm from the bottom edge of the dipstick, then there will be no need to add oil. Otherwise, the operator must add the missing amount of water.
It is necessary to change the lubricant in a cool walk-behind tractor gearbox only in this case, if it has been found that it is painted black, almost dark. Another indicator of the need for urgent replacement. in the lubrication of a huge number of third-party inlaid and hard fractions.
Engine
The Agat L-6.5 model is equipped with a 4-stroke petrol engine Lifan 168F-2 (China) with overhead valves. This unit is characterized by low noise and vibration levels, efficiency and a long service life. Thanks to the automatic decompressor system, the effort when starting the engine is significantly reduced, and operating efficiency increases. The engine is available with an electronic ignition system.
The Lifan 168F-2 power plant is used in a variety of garden equipment, generators, motor pumps and snow blowers. This model is one of the most popular due to its combination of durability, reasonable cost and ease of use.
Characteristics of the Lifan 168F-2 engine:
- working volume – 196 cc;
- rated power - 6.5 hp;
- maximum torque – 11 Nm;
- number of cylinders – 1.
Fuel consumption
Average fuel consumption for the Agat 6.5 Lifan model is 394 g/kW per hour (approximately 1.2-1.5 l/hour). Fuel tank capacity – 3.6 l.
Is it necessary to add oil to gasoline for a walk-behind tractor?
The answer to this common question can be given based on the type of industrial motor of the existing walk-behind tractor. Agricultural units are equipped with 2 or 4-stroke power units. Gasoline for a walk-behind tractor with a factory 2-stroke engine must be diluted with engine oil, always adhering to the proportion shown by the manufacturer's brand.
It is important to keep in mind that 2 and 4-stroke internal combustion engines operate on different principles. Fuel combustion in engines of the first type occurs continuously in 2 strokes. With all this, the branded oil with which the fuel mixture is prepared. Contains not only lubricating components, but also additives that improve fuel quality. In 4-stroke industrial engines, oil and fuel for the walk-behind tractor are always poured separately, into tanks specially designed by the manufacturer for this purpose.
Reviews
- I bought an Agat 6.5 Lifan walk-behind tractor in the spring of 2015. The extensions did not immediately fit the wheels, since the diameter of the bushings turned out to be smaller than the diameter of the shaft. As a result, I bought additional extension cords. There was less oil in the gearbox than required, again I bought it myself. The engine, although Chinese, worked quite well. There were no complaints against him at all. There was almost always enough engine power. Oil leaked from the bolts in the gearbox several times, but this did not cause any serious problems. True, the oil had to be topped up after the end of the season. The drive belts shattered again on the second one at the end of the season. There have been no other problems so far. In general, for its price category I think the walk-behind tractor is quite tolerable.
- Agate 6.5 Lifan is an excellent and reliable machine. Over the 6 years of operation there were a minimum of breakdowns and planned replacements. During this time I had to additionally buy 2 belts and several candles. Scheduled work includes an annual oil change in the gearbox and engine. The walk-behind tractor is very convenient and maneuverable. The presence of reverse speed allows it to be used in small areas. The center of gravity is very low, which adds comfort during operation. Among the shortcomings, I would like to highlight the ill-conceived location of the speed switch - you have to bend down to switch them. The Lifan engine is very reliable and allows you to work on any soil. I recommend this walk-behind tractor to everyone.
- I spent a long time choosing a device for working on the site and settled on the Agat 6.5 Lifan model. Everything was decided by an acceptable ratio of power, quality and cost. I bought the device in May 2013. The first launch went well. Already during the run-in, he began to cultivate the land. I have never had any problems starting the unit. Moreover, the Lifan engine performed excellently even at low temperatures. The walk-behind tractor worked perfectly for 3 seasons. Last year I bought additional equipment (a plow and a potato digger). Installing and working with them did not cause any problems. For my small plot (15 acres), this walk-behind tractor turned out to be ideal.
- I purchased Agat 6.5 Lifan equipment in the spring of 2015. Halfway through the first season, both internal belts broke. During the inspection, I found several burrs on the inner gear pulley. I managed to remove them myself using a file. There were no more problems with the walk-behind tractor. It withstands high loads quite well and does not become capricious in difficult conditions. It uses very little gasoline - with intensive work, about 1.4 liters per hour. So far, Agat 6.5 Lifan delivers positive emotions.
How much oil is required for a walk-behind tractor engine?
Before pouring new oil into the walk-behind tractor without the help of others. The owner of agricultural machinery must find out how much water is already in the internal combustion engine. It may well be that at this moment a complete replacement of the existing lubricant is NOT required, and instead you can simply add the missing amount of technical water.
To independently check the level of contents in the oil tank, you need to:
- Unscrew the plug of the standard filler hole provided in the crankcase of the utility walk-behind tractor;
- Insert the oil dipstick into the factory engine crankcase through the hole provided by the manufacturer, remove it and check the oil level;
- There are special marks on the built-in probe, usually they are marked “MIN” and “MAX”. After removing the dipstick, you need to look at what mark the oil stain is located. It should be placed in the middle between these marks. If the water level is below o, it means you will need to add lubricant;
- If the probe used has industrial marks, then the operator will have to navigate along the length of the device. After measuring the volume of water, its volume should reach the middle of the probe;
- In some cases, the operator may NOT have a probe. In this case, the amount of lubricant can be checked visually. To do this, you need to look through the filler neck. if the water level actually reaches the neck, then the owner does not need to add engine oil for the walk-behind tractor.

After independently checking the level of the existing lubricant, you must close the standard filler cap very tightly and make sure that the liquid does NOT leak out.
Why does the walk-behind tractor stall under load?
A fairly common problem is that the equipment stalls after 5 minutes of operation. Often the reason is a fuel supply failure and ignition problems.
If the equipment stalls during operation, you need to check how well the fuel is supplied:
- The candle is taken out and examined. It is overdried - this indicates a lack of fuel;
- There must be enough fuel in the gas tank for the normal functioning of the machine;
- The condition of the fuel valve is inspected. It may simply be blocked. Sometimes it is enough to open it for further use of the unit.
The walk-behind tractor starts and stalls if there is a problem with the ignition. First you need to check the spark plugs. Wet elements indicate breakdown. It is necessary to re-adjust the ignition system of the equipment.
Resetting is done as follows:
- The cover is removed, which protects the parts of the ignition system;
- The engine flywheel rotates until the contacts in the magneto open;
- A special feeler gauge measures the gap from the “anvil” to the “hammer”;
- The flywheel rotates until the piston is compressed. The latter must reach its peak;
- The flywheel turns again until a characteristic knocking sound is heard, which will indicate the operation of the overrunning clutch;
- The flywheel turns in the other direction until the mark of this element coincides with the mark on the body of the unit;
- The gap from the interrupting contact to the cam is set to 0.3 millimeters;
- The cam is fixed with a screw, which is located above the element, and a protective cover is installed in the equipment body.
If the above steps are performed correctly, the walk-behind tractor will not stall under load. When tilted, equipment may stall if there is not enough fuel in the gas tank. The unit must be installed straight and the starter cable removed. If the engine starts, you need to fill the tank with fuel.
Oil for diesel walk-behind tractor
Engines that are fueled with diesel. They differ from gasoline power units. Accordingly, to maintain their uninterrupted operation, it is necessary to choose a completely different type of lubricant.
The main factor when purchasing lubricant for a diesel industrial engine. this is its viscosity, marked with the SAE designation with the following set of letters and numbers.
The latter will tell the buyer under what specific criteria it is best to use the selected lubricant:
- SAE 0W, SAE 5W or SAE 20W. designed for use in regions with severe, long winters;
- SAE 20, also SAE 40, SAE 60. Marking without letters means that this is a highly viscous liquid that has proven itself well in hot summer weather;
- SAE 5W-30, SAE 10W-40. all-season oils that work great both in winter and hot summer.
The systematization presented by the South American Petroleum Institute divides motor oils for household and professional walk-behind tractors according to their operational groups. Accordingly, the following types of lubricants are found on the market:
- API CJ-4. used in branded, cool, very massive motors, which are designed specifically for operation under the highest loads. Experienced gardeners advise using factory oils of this particular type for daily lubrication of engines produced by the BriggsStratton and Honda brands;
- API CC. used for power units without an integrated supercharger and with turbocharging. These oils provide continuous protection of built-in motor parts from corrosion, the formation of tarry deposits and excessive wear.
When choosing oils of THESE types, it is necessary to pay special attention to their manufacturers. It is best for users to trust well-known companies, which include the brands Elf, Liqui Moly, Motul, Shell and others.

Is it possible to fill a walk-behind tractor with motor oil?
The difference between internal combustion engines for walk-behind tractors used on farms and modern cars is:
- Factory design specifics;
- Force level;
- The material from which motor components are made.
The introduction of industrial motor oil for continuous lubrication of the internal combustion engine parts of a walk-behind tractor evenly leads to accelerated wear of the standard shiny cylinders of the latter, its piston group, once a day, as well as mechanical damage to the carburetor, industrial filter parts and rubber fuel pipes.
Features of operation
All Agat walk-behind tractors undergo comprehensive pre-sale factory training and testing, so they are delivered almost fully assembled, filled with all oils and ready for work. The machines are distinguished by a reasonable, uncomplicated design, so their operation is not particularly difficult even for beginners.
Compliance with the requirements of preventive and routine maintenance in accordance with the operating instructions can significantly extend the service life of the equipment.
The operating instructions for the Agat L-6.5 walk-behind tractor are here.
Service
Engine oil for the Agat walk-behind tractor is selected strictly in accordance with the operating instructions, depending on the brand of the engine. The gearbox requires TAD-17I or MS-20 oil. Walk-behind tractors consume unleaded gasoline AI-92. V-belt size and profile: A-1120 13 mm wide.
First launch, run-in
The first 25 engine hours of operation of the Agat walk-behind tractor are a break-in period - breaking in and lapping of the main components and mechanisms. The break-in procedure should be carried out in a gentle manner, avoiding high loads. Cultivation must be carried out gradually in 2-3 steps, starting from 10 cm in one pass. The throttle valve can be opened no more than 3/4 of its full travel.
Idle operation of the walk-behind tractor is possible for no more than 10 minutes. On heavy clay soil, the machine can work for no more than 2 hours, after which a break is necessary. After break-in, change the oil in the engine and transmission units of the unit.
Major faults, repairs
Agat walk-behind tractors are distinguished by a simple, rational design. Possible equipment malfunctions can often be caused by operational errors. Thus, uneven rotation of the cutters can be caused by the adhesion of wet soil or the entry of foreign objects into the work area. Also, belt slippage should be prevented.
If the cutters stop rotating when the engine is running, it is necessary to check the clutch cable - it may break. Another reason: the V-belt has come off the pulley or has broken.

Why does the walk-behind tractor work intermittently?
There are other faults that are worth considering:
Removing the speed limit on engines type 168F-2
- The walk-behind tractor engine is running backwards. The reason is often the use of bad fuel. It will not be enough to replace the fuel. The pump and fuel supply hoses are washed;
- The equipment works in jerks. The engine does not warm up completely. You need to turn off the engine and wait for it to cool completely. Then restart it and warm it up for at least ten minutes;
- The engine does not pull, therefore the engine power decreases. The filter system is checked and cleaned. The problem can be caused by wear of the ignition magneto. In this case, the part is replaced.
Owners of both gasoline and diesel vehicles may encounter such problems. Regardless of the specifics of the breakdown, you must urgently stop using the unit and start fixing the problem.
How to choose oil for a walk-behind tractor?
Its factory management for constant use will be able to provide accurate information about a suitable branded lubricant for the built-in motor of a walk-behind tractor. Usually, the manufacturer indicates the type of water, its base and the manufacturer’s brand. The company manual also contains instructions from the manufacturer of the equipment, telling you how much lubricant needs to be poured into the factory engine and how exactly to do it correctly.
But not everyone has the original manual for the walk-behind tractor they are using. In this case, the operator needs to understand that, depending on the initial purpose, 2-stroke and 4-stroke factory oil are available on sale. In most cases, utility walk-behind tractors are equipped with industrial 4-stroke engines, but before purchasing lubricant, it is still better for the user to study the markings stamped on the wall of the engine in advance.
Another important factor when choosing process water. this is its density. The oil must entwine the moving parts of the internal combustion engine of the walk-behind tractor, and for this it must be moderately colored and quite viscous. However, you should not choose a very thick liquid, otherwise it will not be able to penetrate into the smallest grooves of an industrial motor.
