Abstract
A mechanism for selectively adjusting the cutting height of a mower deck carried by a vehicle having a frame. A laterally extending lift handle formed of a plastic material is engagable by the hand of the operator, and is pivotally coupled with the vehicle for pivoting motion about a generally horizontal axis as the operator lifts the first end portion. A pair of laterally spaced and generally spherical sockets are formed integral with the lift handle between the lift handle's first and second end portions. Each socket pivotally supports a ball member. Link members are provided having first portions coupled with respective ball members, and second portions pivotally coupled with the mower deck for vertically shifting the deck relative to the vehicle as the lift handle pivots. A four bar linkage is coupled between the vehicle and the deck for maintaining the deck in a generally level position throughout the deck's vertical range of motion.
