ABSTRACT:
An arrangement is provided for leveling the blade housing of a mower. The housing is suspended from the underside of a vehicle frame by pairs of connecting links pivotally connected to the housing and the frame. A pair of fixed plates, secured to opposite sides of the housing, are joined by pivotal connections to respective adjusting plates. The associated pairs of fixed and adjusting plates are provided with overlying slots which receive respective pins provided with locking structure which are selectively operable to lock the respective fixed and adjusting against movement relative to one another. At least one of the pins also extends through an aperture in a lift link. An operator-controlled lift lever is joined to a lift pin which passes through a slot in said lift link whereby actuation of the lift lever causes the housing to be raised or lowered. When lowered to engage the ground, unlocking of the pins permits the entire housing to be moved so as to be oriented with respect to the ground's surface whereby on re-locking of the pins and raising the housing, the housing is leveled relative to the ground.
