| PURPOSE:To improve the mowing height controlling operability and the durability of a lawn mower. CONSTITUTION:This mowing height controlling structure supports a mower 2 on a mobile machine body by suspending the mower through a link mechanism in vertically movable manner and enables the lifting of the mower 2 with a lifting operation tool 14. The controlling structure is provided with a mobile member 24 interlocked with the lifting operation during the interlocking motion of the link mechanism and a checking member 26 to check and inhibit the lowering motion of the mower 2 by contacting with the mobile member 24. The checking member 26 forms contacting parts 28 having successively varying height along the rotational axial direction according to the rotating operation. The lower limit of the mower 2 can be set by preferentially contacting the mobile member 24 with any one of the contacting parts 28. | ||||||
