Abstract: A lawn mower comprising a blade housing supported above the ground by wheels, and a blower case removably connected to one lateral side of the blade housing for blowing grass clippings toward a grass catcher disposed rearwardly of a vehicle body. The blade housing carries wheel support frames secured thereto and extending in a fore and aft direction of the vehicle body. A forward coupling and a rear coupling are secured to one of the wheel support frames for connecting the blower case to the blade housing.

Abstract: A connecting link structure for connecting a grass cutting unit to a position between front and rear wheels of a riding type lawn mower. The link structure comprises parallel front links and parallel rear links each pivotally connected at one end thereof to a vehicle body and at the other end to the grass cutting unit. A curved bracing auxiliary link extends from the pivotal connection between the vehicle body and one of the rear links, along this rear link, and then perpendicular to the other rear link to be secured to the other rear link at a point offset from the pivotal connection between the other rear link and the grass cutting unit.

Abstract: A device for attaching a working implement to the front of a running vehicle for performing work while following the ground comprises a pair of opposite inflexible links pivoted at their rear ends to the front of the vehicle. These inflexible links are movable upwardly or downwardly and each link has a front end for movably supporting the front portion of the implement about a lateral pivot. A pair of opposite suspenders are each mounted on a longitudinally intermediate portion of each link for suspending the rear portion of the implement, each of the suspenders including a rod assembly pivotally connectable to the implement's rear portion and a resilient member. The rod assembly is inserted in an upstanding state through the link and is movable axially thereof to thereby permit upward or downward movement of the implement's rear portion due to the movement of the implement about the pivot.
