DIAGNOSTIC PROCEDURES

A farm tractor is a self-propelled machine to be used with various implements. To reach the highest efficiency a driver of a farm tractor must know the constructive features of the machine, ways to adjust its systems, and must provide good maintenance of all its units and fast and proper attachment of farm equipment. The driver has to get the tractor ready¹ for the operations to be performed. To work with mounted or semi-mounted² implements the driver must prepare the hydraulic system, switch on the oil pump, and adjust the three-point linkage. The width between the wheels should be changed according to the crop rows. The diesel engine must be started during not more than 5 minutes. The starter must operate steadily at minimum, maximum revolutions and at full loading. The tractor with the electro starting engine must be easily started. The engine must operate at all modes without faults or smoke. For tractor overloading a small amount of smoke is permitted.

The clutch must be easily depressed disconnecting the engine and the transmission. When the clutch is on, it provides an easy start and easy gear shifts. The gearbox, the rear axle and the terminal gears must operate with steady noise. The noise can't be sharp.

The levers, pedals and brakes must move easily. The blocking of the differentials or rear wheels must be switched on and off easily.

The drive gear to operate the PTO-shaft must be switched on and set at the proper rotation speed. The checking³ devices and warning lights⁴ for the tractor systems are to be examined as well.
