Claims

[Scope of utility model registration request]

A driving side wheel that is interlockingly connected to the prime mover and two driven side wheels that are interlockingly connected to the crawlers on both sides of the machine are inserted into the rotating shaft that is mounted inside the minsion case. Clutch teeth are formed between the and the driving side body, and each driven side wheel body is moved on the rotation axis by the piston device,
A pressure switching valve for switching the working hydraulic pressure of the piston device between high pressure and low pressure is provided in the combine harvester, which transmits and cuts off power to the crawler and performs braking, and the switching valve is used to operate the piston device. The pressure switching valve is connected to a lever so that the lever operates the pressure switching valve together with the piston device, and the operating load of the operating lever is increased when switching the pressure switching valve to the high pressure side. combine.
