Engine and Performance
The tractor is powered by the UTB D2601.000 liquid-cooled 6-cylinder diesel engine, displacing 4.7 liters. It produces 83 horsepower (61.9 kW) at a rated speed of 2400 RPM, with a peak torque of 170 lb-ft (230.5 Nm) reached at 1500 RPM. The engine utilizes an oil bath air cleaner with a cyclonic pre-cleaner to maintain performance in dusty environments.

Power is delivered through a 330.2mm dry disc clutch to either a 4x2 2WD system or a 4x4 MFWD system (on the 850DT model). Final drives are of the planetary type.

The hydraulic system is an open-center design with a pump flow capacity of 8.2 gpm (31.0 lpm). The rear hitch is a Category II system equipped with draft and position control. The independent rear PTO supports dual speeds of 540 and 1000 RPM, achieved at engine speeds of 2125 and 2400 RPM respectively.
