Abstract
A self-propelled utility tractor having articulated steering, a standing operator, a turning radius near the rear wheel on the inside of a full turn, the radius of turn being not substantially longer than the wheel base, independent rear wheel brakes to assist in tight turns, a steering wheel for operating a steering linkage, an engine and transmission, centrally mounted with the engine below the transmission transmitting power by a jack shaft so the out put shaft of the engine extends down to power an attachment. Where the attachment is a mower deck, a rear discharge chute on the tractor deflects the clippings uniformly across the rear to avoid wind rowing. Flexible elements rotate above the mower blade to provide additional mulching and turbulent air flow and self-cleaning of the underside of the deck.
