A farm tractor can look uncomplicated from a distance: engine at the front, operator in the middle and big tyres at the back. Spend some time around one and you soon realise that several different systems are working together.<\/p>\n

The engine has to get power to the driving wheels. Hydraulics have to raise or control implements. The PTO can send rotating power to equipment behind the tractor. Steering, brakes, axles, hitching points and electrical components all have their own jobs.<\/p>\n

Basic mechanics starts with noticing change.<\/strong>

A hydraulic lift that becomes slower, steering that develops more play, a vibration that appears only with the PTO engaged or an engine that starts running hotter than usual all mean more when you know which system you are looking at.<\/p><\/div>\n<\/section>\n\n

Quick answer<\/span>

What are the main parts of a farm tractor?<\/h2><\/div>\n

The main parts include the engine, fuel and cooling systems, clutch or drive-control system, transmission, differential, final drive, chassis or main structure, axles, steering, brakes, wheels and tyres, hydraulic system, three-point hitch, drawbar, power take-off (PTO), electrical system and operator-protection structure<\/strong>.<\/p>\n<\/section>\n\n
