PROBLEM TO BE SOLVED: To provide a gear transmission of which the assembling property is good, and which can be made compact. SOLUTION: Power from an engine 3 is input into a mission case, and the power is transmitted to a PTO shaft 12 which protrudes from the front part of the mission case through a PTO clutch. At the same time, the power is gear-changed by right and left HST type gear-changing devices, and transmitted to right and left axle shafts 1L, 1R by this gear transmission. In the gear transmission, the mission case is constituted of a front section case 5, an oil pathway plate 14 which is arranged on the rear surface of the front section case 5, and rear section cases 4L and 4R which are arranged on the rear surface of the oil pathway plate 14. The rear section cases 4L and 4R are divided into the right and the left, and the HST type gear-changing devices are housed in the rear section cases 4L and 4R. COPYRIGHT: (C)2005,JPO&NCIPI
