ABSTRACT:
An improvement in a power transmission arrangement in a four-wheel drive tractor which includes an engine, an oil sump containing a reservoir of lubricant for the engine and wherein power is transmitted from the tractor gearbox or from a separate power take-off gearbox to the differential gear of the front axle by a power transmission member. A power take-off shaft is provided at the front end of the tractor for transmitting power from the engine crankshaft to external equipment. According to the invention, the differential gear of the front axle, the four-wheel drive clutch which couples the transmission member to the front axle differential gear, at least part of the take-off shaft clutch and other transmission elements for the take-off shaft, and the hydraulic steering pump are situated within the oil sump. The invention further includes operating the four-wheel drive clutch and the differential lock thereof, and the take-off clutch by means of the engine lubricant contained in the oil sump. The components of the power transmission arrangement situated within the oil sump are at least partly supported on the oil sump which is arranged to act as a load carrying component of the tractor frame.
