Abstract
A tractor with a front wheel suspension and mechanical front wheel drive wherein the front wheel drive differential case includes an engine oil sump replacing the need for a separate engine oil sump and wherein the suspension control arms are mounted to the differential case through integrally formed mounting structures in the differential case. These mounting. structures reduce the number of front end components thereby improving the packaging of the suspension, steering and front wheel drive. The elimination of the oil: pan allows the front axle ground clearance to be increased while improving ground visibility in front of the tractor over the hood.
