摘要： An improved vehicle control system for a vehicle having an engine which produces output torque through an output sheave and a transaxle mounted to the vehicle's frame, the transaxle being selectively operational in forward, neutral and reverse modes in response to a mode selection link operatively connected to the transaxle. The transaxle functions as a gear box having a single gear ratio between the input sheave and the drive axles in both the forward and reverse operating modes, a transaxle and a brake. The output sheave of the engine is in communication with the input sheave through a first and second belt drivingly mounted to a plurality of sheaves and a variator such that an increase in tension on a first belt causes the variator to increase the rate of rotation of a second belt. A speed range sheave mounted to an arm is operatively connected to the first belt. A single lever is mounted to the vehicle such that the arm is selectively positionable to effect the rotation rate of the second belt through the variator which determined the speed of the vehicle. The position of the arm is also altered by displacement of a clutch rod in such a manner that when the clutch rod is returned to the engaged position, the vehicle will resume to its previously selected speed.

摘要： 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 suppports 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.
