Components of power tiller

A power tiller consists of the following main parts:

• Engine
• Transmission gears
• Clutch
• Brakes
• Rotary unit
All the power tillers are fitted with an I.C. engine. At present, most of the power tillers are fitted with diesel engine. Only Iseki make have used kerosene engine. Other makes like Kamco, Mitsubishi, Krishi, Yanmar and Satoh have used diesel engine in India.

Operation

• The main clutch is a lever on the handle.
  
• The lever can be shifted to on or off position while operating in the field.
  
• When the lever is shifted to on position, the power from the engine is transmitted through the main clutch to the various parts of power tiller.
  
• When the lever is shifted to off position, the power from the engine is cut-off from the rest of the transmission.
Power transmission in power tiller

• For operation of power tiller, the power is obtained from the I.C. engine, fitted on the power tiller.
• The engine power goes to the main clutch with the help of belt or chain.
• From main clutch, the power is divided in two routes, one goes to transmission gears, steering clutch and then to the wheel.
• The other component goes to the tilling clutch and then to the tilling attachment.
