Self-service cultivator
The cultivator consists of a gasoline engine with a volume of 120 cm3, the air filter, the fuel injection system, the gearbox and the working shaft on which the cutters or other attachments are installed. Some manufacturers supply the cultivator with additional attachments: a plow or a potato digger. All this equipment must be looked after, otherwise the cultivator will quickly fail.
Consider cultivator device on the example of the MTD T-380 B 700 model.
Cultivator device
This cultivator is equipped with a Briggs & Stratton B&S 700 Series OHV gasoline engine with a volume of 163 cm33... The torque from the engine is transmitted to the chain reducer using a belt drive. The chain reducer transmits the torque to the working shaft, on which there are 8 cutters with a diameter of 30.5 cm. The maximum working width of the cultivator is 81 cm. The horizontal position of the cutters is manually adjusted. After processing an area of 30 acres, the cutter blades must be sharpened.
Before starting the cultivator, check the engine oil level. This can be done by unscrewing the plug of the special hole located in the side of the cultivator body. If oil starts dripping from the engine, it means that its level is sufficient. Since the cultivator has a four-stroke engine, there is no need to add gasoline to the oil.
After checking the oil level, the engine must be filled with fuel. The cultivator is filled with A-92 gasoline. The engine is equipped with a coarse fuel filter, which prevents the carburetor jets from clogging. Next, you need to check the condition of the belt drive. After digging every 20-30 acres of land, you need to fix the belts connecting the gearbox and the cultivator motor. Due to vibrations, they can move, then the engine will overheat, and the gearbox itself may fail.
It is also necessary to clean the cultivator exhaust pipe annually. After prolonged work, it clogs up with smoke. Due to the decrease in thrust, combustion products accumulate in the engine, and it breaks down.
Every 5 years, the cultivator engine is disassembled and the fuel filter and spark plugs replaced. In order to extend the life of the spark plug, it is necessary to remove the high-voltage wire from it after digging. The high-voltage wire is replaced every 10 years. It is also necessary to lubricate the gears of the working shaft annually.
