Abstract

An engine, through a suitable transmission, drives the traction wheels of a garden tiller in a forward direction. The engine also drives the tine shaft and tines through another transmission and a differential. The second transmission contains a gear arrangement by which the tine shaft may be rotated in the same direction as the traction wheels at one time, and in an opposite direction at another time, a neutral position also being provided. The second transmission includes a splined shaft which drivingly engages a gear which is slidable thereon. An output gear is provided in this second transmission and it may be drivingly connected to the slidable gear for rotation in a given direction by means of a plurality of pins carried on the output gear and received within appropriate holes provided in the slidable gear. Right and left cluster gears are mounted on a common shaft. A gear idler is mounted on yet another shaft and this gear idler constantly meshes with the output gear and with the right hand cluster gear. The slidable gear may be slid to a neutral position wherein it no longer engages the pins and wherein it does not engage the left hand cluster gear. The slidable gear may be moved to a further position where it engages the left hand cluster gear. This latter position results in the output gear being driven in the opposite direction via the splined shaft, the slidable gear, the left hand cluster gear, the right hand cluster gear and the gear idler.
