IMPLEMENT WORKING HEIGHT-ADJUSTMENT MECHANISM Abstract of the Disclosure A vehicle includes hydraulically actuated lift arms which are pivotally connected to central locations of the top of a mower blade housing and are operative for moving the mower vertically between working and transport positions. When the mower is in its working position, a pair of caster wheels supports the front of the blade housing while the rear of the housing is supported from the lift arms by a pair of suspension assemblies. Each of the suspension assemblies includes a fore- and-aft extending adjuster screw which is operable for effecting selected fore-and-aft movement of an adjuster bracket, which is connected to an associated lift arm by a chain, so as to cause the rear end of the housing to be adjusted vertically. These suspension assemblies cooperate with adjustment mechanisms associated with the caster wheels to place the mower at different cutting heights.
