Types of Farm Machinery and Their Uses

Tractor:

Description:

• A tractor is a powerful and expensive multi-purpose motor vehicle used for lifting or pulling farm implements.

• It has a hydraulic control system which lifts mounted implements under the control of the operation.

• It has a Power-Take-Off (PTO) shaft that transmits power from the tractor’s engine to PTO-driven machines or implements like Ploughs, Harrows, Harvesters, Planters and others.

• It has four wheels with rubber tyres.

• It consists of an internal combustion engine which uses diesel or petrol without spark plugs.

• The power produced in the engine is transmitted to the wheels and PTO by the transmission parts. The power take-off shaft then transmits power from the tractor’s engine to PTO-driven machines or implements. For example, in a mower, PTO transfers power from the engine’s drive pulley to the blades. In most cases, this power transfer applies to a secondary shaft that drives a hydraulic pump, generator, air compressor, pneumatic blower, or vacuumA vacuum is an area of space containing little or no matter (solids, liquids, and gases). It is a space with nothing in it, not even air. More pump.

• Popular brands of tractors include: David Brown, Massey Ferguson, Ford and Fiat.

Functions of Parts of the Tractor:

(i) Three-point linkage:

• Point of attachment for coupled implements.
• Allows the raising and lowering of implements.
• Regulates the depth and variation of thrust/depth of plough according to soil conditions.
• Helps to maintain a constant draught/force.
• Helps in the transfer of weight to the rear wheels of the tractor.
