に取付けてある作業車の走行用変速装置。The first and second gears are connected in series and are variable in height and low.
Gear transmission6. Each of the transmissions 6 and 7 is provided to be swingable by a single shift lever 18 that can swing in a cross direction, and by a series of operations of the shift lever 18, both transmissions 6 and 7 are brought into a low speed state. a first speed state in which the first transmission 6 is in a high speed state and the second transmission 7 is in a low speed state; and both transmissions 6 and 7.
This is a traveling transmission device for a work vehicle configured to alternatively bring about a third speed state in which the speed change lever 18 is a high speed state, and the operation path 23 of the shift lever 18 is directed upward or in the longitudinal direction of the machine. The first and second end-side path portions 2'3a, 23b communicate with each other, the lower end or front end of the first end-side path portion 23a, and the upper end or rear end of the second end-side path portion 23b. Formed in a substantially Z-shape consisting of a connecting intermediate path portion M in the lateral direction of the aircraft (1. Between each of the two speed change operation parts 27.31 and the speed change lever 18, the speed change lever 18 and An engagement mechanism 34a or 34b that enables the gear shift operation parts 27 or 31 to swing together is provided in a state that is engaged and disengaged by the rocking of the gear shift lever 18 in the direction of the body lateral force, and one of the gear shift operation parts 27 is , the first transmission 6 is in a low speed state when it is at the first end L of the operation path 23, and is in a high speed state when it reaches the intermediate route portion M. When the second transmission 7 is in a low speed state when the other gear shift operating section 31 is located at the intermediate route section M, and when the other gear shift operating section 31 is located at the end H of the operating route 23, the second transmission 7 is in a low speed state. 2. A traveling transmission for a working vehicle, which is installed so that the transmission 7 is in a high-speed state.
