Claims

[Scope of utility model registration request]

In a tractor power transmission device in which engine power is increased or decelerated by a transmission device in a transmission case provided at the rear of the vehicle body, and then transmitted to a rear axle via a differential shaft, the differential shaft is connected to the transmission case. A counter shaft that penetrates the side wall of the case and extends laterally, and is provided at the rear of the differential shaft is pivotally supported by the side wall of the transmission case and extends laterally, and the differential shaft and the counter the shafts are connected to each other via a first reduction gear in a reduction gear chamber formed between the transmission case side wall and a rigid partition plate fixed to the side wall, and on the outside of the partition plate, A brake chamber is formed that is surrounded by a brake housing that is fastened together with the partition plate and fixed to the side wall of the transmission case, and the differential shaft is braked in the brake chamber, and the braking reaction force is transferred to the partition wall. 1. A power transmission device for a tractor, comprising: a brake device received by a plate; and an end portion of the counter shaft extending into the brake chamber is connected to a rear axle via a second reduction gear.
