ABSTRACT:
A mower deck lift mechanism which includes a friction disk selectively pivotable into engagement with first and second pulleys of a double pulley jacksheave. A linkage coupled between the friction disk and the deck raises the mower deck when the friction disk engages and rotates with the first pulley, and lowers the deck when the friction disk engages and rotates with the second pulley. Neutral return mechanisms are provided for returning the friction disk to a neutral position when the operator releases a control and when the deck approaches its extreme raised or lowered positions. A cutting height preset mechanism is also provided.
