There is disposed a wheel tread adjusting apparatus for a vehicle having a main axle case supported by a vehicle body and slidable cases mounted in right and left ends of the main axle case, respectively, the slidable cases being slidable transversely of the vehicle toward and away from each other. A fixing plate extends between the main axle case and each of the slidable cases, and is secured to one of the two cases. The fixing plate is positionally adjustably lockable to the other of the two cases.

Wheel tread adjusting apparatus

A change-speed apparatus in a tractor equipped with an engine has a planetary gearing mechanism settable between its two positions. Actuation of the mechanism to one of the two positions is hydraulically power-actuated, while actuation to the other of the two positions is automatically effected, as the hydraulic power is released, by a resiliently urging spring. Power-transmitting operative connection is therefore always maintained between the engine and running-drive wheels even when the hydraulic actuation power comes to extinct.

Change-speed apparatus in a tractor

An operating lever assembly for a farm tractor comprising a first block attached to a side wall of a transmission case, a second block disposed close to a driver's seat, turning shafts mounted on the first block and operatively connected to operating rods projecting from the side wall of the transmission case, operating levers mounted on the second block, and coupling means operatively connecting the turning shafts to the operating levers.
