ABSTRACT:
A transmission for a tractor comprising a power takeoff line change speed gear mechanism, propelling line change speed gear mechanisms and a backward and forward drive switching mechanism. The propelling line change speed gear mechanisms include a main change speed mechanism, an auxiliary change speed mechanism and a front wheel change speed mechanism. The power takeoff line change speed mechanism, and the main and auxiliary change speed mechanisms somewhat encircle a longitudinal center line transversely of the transmission. The backward and forward drive switching mechanism and the front wheel change speed mechansim are juxtaposed in a region immediately forwardly of the change speed machanisms B, C and E. Further, the drive switching mechanism, the auxiliary change speed mechanism and the front wheel change speed mechanism F are disposed on one lateral side of a longitudinal plane from a front end of the tractor to a rear end at a substantially mid-position of the transmission while the power takeoff line change speed mechanism and the main change speed mechanism are disposed on the other lateral side thereof.
