Abstract
A riding mower is provided having a generally conventional engine, seat, frame, cutting deck and hydrostatic transmission. The cutting deck may be vertically adjusted for a plurality of cutting height settings, and may be locked in its uppermost setting and returned to the pre-selected cutting height, by selective operation of a foot-operated pedal. Linkage connects the pedal to the deck and to a variable-height adjustment link. A transmission speed control includes a handle protruding upwardly adjacent the seat, connected to a transverse control rod with a distal end operatively secured to the conventional speed adjustment mechanism of the transmission. Positioned adjacent the distal end of the control rod is a friction-generating device which engages the rod and prevents unintentional movement thereof. A grass collection bag is included with a blower mounted on the cutting deck for providind an enhanced airflow from the cutting deck through the duct leading to the bag.
