トラクタにおける前輪増速操作装置。 A front wheel transmission having a drive state switching mechanism is interposed in a front wheel transmission system, and an operation mechanism includes the drive state switching mechanism and a switching lever for switching to a front wheel non-drive position, a front wheel drive position, and a front wheel acceleration standby position. A linking device is inserted between the drive body and the driven body with a predetermined play gap and biased in one direction by a pressure mechanism, and the switching lever of the operating mechanism is moved to the front wheel speed-up standby position. The drive state switching mechanism is configured to be able to switch to the front wheel speed increasing position in conjunction with the turning operation of the aircraft in a state where the drive state switching mechanism is set to 1. A front wheel speed increasing operation device for an agricultural tractor, characterized in that the front wheel speed increasing operation device for an agricultural tractor is provided with a lever guide that allows further operation against the force direction.
