Abstract
A multistage change-speed apparatus for a tractor has a running-travel-system change-speed gearing apparatus, a planetary gearing reduction apparatus operatively connected to that apparatus, an intermediary transmission shaft driven by this apparatus, a speed-reduction shaft disposed beneath that shaft, a bevel pinion shaft disposed in parallel with this shaft, an auxiliary change-speed gearing apparatus disposed between these two shafts, and a differential operatively connected to that apparatus. The planetary gearing reduction apparatus is shiftable between the operative state and the inoperative state.
