Claims

[Scope of utility model registration request]

A pair of left and right brake devices that brake left and right drive wheels independently, a pair of brake pedals connected to these brake devices, a hydraulic continuously variable transmission connected to the drive wheels, and a hydraulic continuously variable transmission connected to the drive wheels. In a work vehicle having a gear shift pedal for operating a gear change gear, and a lock mechanism for locking the gear shift pedal at an arbitrary shift position, when the pair of brake pedals are simultaneously operated for braking, the gear shift pedal is locked by the lock mechanism. A gear shift pedal lock release device for a work vehicle, characterized in that a release mechanism is provided for releasing the locked state of the gear shift pedal.
