A riding tractor in which engine output is transmitted to a running device through a hydrostatic stepless transmission. The tractor has a braking device for acting on the running device, a first brake operating device and a second brake operating device operable independently of each other for operating the braking device, and a brake control device for linking control displacements from the first brake operating device and the second the brake operating device to the brake device. The brake control device includes a mechanism movable with the operating devices to maintain the second brake operating device in an inoperative position when the first brake operating device operates the brake device, and a brake lock mechanism switchable between a locking state for locking the brake device to a braking position, and a lock release state, the brake lock mechanism maintaining the lock release position when the first brake operating device operates the brake device, and automatically switching to the locking state when the second brake operating device operates the brake device to the braking position.
