Abstract

A lift mechanism for adjusting the height of a mower deck includes a pivotable lift handle, a toothed member carried by the vehicle, and a rod-like member pivotally carried by the lift handle. A first portion of the rod engages the toothed member for maintaining the lift handle and mower deck at selected positions. A second portion of the rod radially offset from the first portion defines the axis about which the rod pivots during operation. First and second arcuate slots receive the first and second portions of the rod. The arc of the first slot has its center at a first position within the second slot, and the arc of the second slot has its center at a first position within the first slot. A blocking member carried by the lift handle is abuttable with the rod for preventing the first portion from pivoting to the first position whereat the second portion can pivot out of the second slot.
