PROBLEM TO BE SOLVED: To ensure protection and safety of a HST because when an mowing is carried out at a higher speed than usual in a small-sized mower, a power system of the HST becomes overload and the moving becomes dangerous. SOLUTION: This mower is constituted so that when a mowing operation crutch is in on-state, a sub-transmission may not be in a mode of the high-speed side for traveling, and in the reverse, when the sub transmission is at high-speed side, the mowing operation crutch may not be in the on-state, to prohibit concurrent movements.
