Abstract
Abstract A self-propelled vehicle has a driver platform pivotally coupled to its frame through one or more arms. The platform can be moved to occupy various positions to facilitate loading and handling. Various implements and other objects can be supported on or coupled to the vehicle by moving the driver platform to accommodate the objects. The entire loading surface supported by the frame can thus be used. Coupling members and lifting devices are mounted on the vehicle to assist in loading, unloading and connecting the objects.
