Abstract
A vehicle power transmission for tractors and the like having a fluid operated speed-change mechanism which comprises a plurality of rotatably mounted speed-change gears arranged on a lay shaft and a plurality of fluid actuated clutches associated with the respective speed-change gears for selectively connecting each of the gears to the lay shaft. A brake is provided which selectively brakes the lay shaft at the non-operation state of the fluid operated speed-change mechanism. The brake prevents unexpected transmission of power through the speed-change mechanism at the non-operation state of the mechanism, thereby preventing problems such as an unexpected start of the vehicle.
