Abstract
A propelling transmission system of a tractor comprising a front transmission for driving front wheels and a rear transmission for driving rear wheels. The front transmission receives drive from an engine mounted at a front position of the tractor, through a main clutch housed in a clutch case, and transmits the drive to the rear transmission. The rear transmission returns part of the drive to a front wheel change speed mechanism included in the front transmission. The front transmission is housed in a front transmission case directly connected to a lower rearward position of the clutch case.
