ABSTRACT:
A "short turn" powered vehicle having a transverse structural mower housing or implement that is used to also vertically stablize the unit. One embodiment uses a self powered mower housing with lateral support wheels which also give lateral support, as do the choice of implements, by means of a vertically restricting hinge in relation to a powered drive wheel; thus the drive wheel is in a floating mode as it gives thurst to the housing or implement, so as to always have traction on uneven ground.
On each of the embodiments steering is done by, either a generally centrally located steered front support wheel steered from a rearward operator's seat on the vehicle, or steering being from an operator's seat rearward on the vehicle, by breaking of either of the housing's or implement's lateral support wheels and there being at least one castor type front support wheel or lateral front support wheels located close to the rear support wheels. Or by hand mower type handles mounted on the rear of the vehicle drive wheel frame, without the operators seat, but with at least one front caster type support wheel. In each of the steering modes, except the one, steering is done by the thurst of the rear drive wheel around one of the laterial housing or implement's support wheels. The vehicle is vertially stabilized by the vertically restricted pivoting hinge with a rear drive wheel that is in a floating mode in relation to the housing or implement.
