ABSTRACT:
A rear axle apparatus for a tractor having differential gear shafts driven by power transmitted from a transmission, rear axles connected to the differential gear shafts through planetary reduction mechanisms, and brakes for braking the differential gear shafts through brake disks engaged with the differential gear shafts. The apparatus includes a rear axle case connectable to a case of the transmission and having an inner peripheral surface. Each planetary reduction mechanism includes a ring gear mounted on the inner peripheral surface of the rear axle case. A brake support receives one of the brake disks. The brake support is mounted on the inner peripheral surface of the rear axle case, and arranged parallel to the ring gear substantially along the rear axles. A rotation stopper limits rotation of the brake support and the ring gear relative to the rear axle case.
