特徴とするトラクタ用トランスミツシヨン。[Claims for Utility Model Registration] The power of the engine 2 is transmitted through a double clutch mechanism 22 to propulsion shafts 23 and 24 that have a dual-shaft structure, the outer shaft being a gear transmission mechanism 28. The inner shaft 23 of the propulsion shafts 23 and 24 is interlocked with the PTO transmission shaft 29 via a gear transmission mechanism 31 that can be freely switched between forward and reverse directions.
A gear transmission mechanism 31 which is interlocked and connected to the PTO transmission shaft 29 and can be switched between forward and reverse directions is built into a case 38, and this case 38 is removably attached to the transmission case 4. A reversing interlocking gear 36 of a gear transmission mechanism 31 that can be freely switched in reverse is fitted on the sleeve so as to be relatively rotatable, and a brake shoe 40 that can freely approach and separate from the reversing interlocking gear 36 prevents the interlocking gear 36 from rotating. A transmission for a tractor, characterized in that the transmission case 4, which is provided in a case 38 and corresponds to the brake shoe 40 on the outside, is provided with a piston ram 42 that presses the brake shoe 40 in a braking direction.
