PROBLEM TO BE SOLVED: To solve the problem wherein a large scaled mower deck is difficult to be installed because grounding travelling length in the back and forth direction is long in the travelling form with a crawler mounted. SOLUTION: The mower deck 6 is arranged mounted in a vehicle body 5, in which an unequal sided triangle crawler 4 formed with a crawler short side part 1, a crawler long side part 2 and a crawler bottom side part 3 is installed, on a side opposite to the crawler short side part 1. With this structure, the triangle crawler 4 is formed into a form that the crawler short side part 1 of the unequal sided form is short and the crawler long side part 2 thereof is projected long in the back and forth direction, and the crawler bottom side part 3 is formed long to stabilize grounding support.
