Abstract: A hybrid drive system for a utility vehicle (1) which operates with an internal combustion engine (12) and an electrical generator (80), motor (86) and storage means (84). Auxiliary hydraulic functions (93,94) may be powered by the electric motor (86). An output of the engine (12) is mechanically coupled to a multi-ratio transmission (10) which has a hydrostatic driveline (24) and an output which is mechanically coupled to propulsion means. With the engine switched off, the electric motor powers a hydraulic pump (91) which generates pressurised fluid to operate auxiliary functions. In addition, the pressurised fluid may be exploited in a secondary propulsion mode to drive a hydraulic motor (92) in the hydrostatic transmission to propel the vehicle in a low emission, low noise output mode.

Abstract: A tractor cab 10 is provided which has a wall portion 16 formed as a double skinned polyethene plastics moulding. The cab also has a tubular ROPS 12 on which the double skinned plastics wall portion is secured. The wall portion includes the wheel arch and fenders of the cab with inner and outer skins 16a, 16b, the inner skin forming the finished inside surface of the region of the cab. The plastics moulding includes moulded channels 16c for receiving part 14 of the tubular cab ROPS. The ROPS is secured to the double skinned plastics moulding with spacers 18, 18a between the inner and outer skins at the points of securement to the ROPS. The inner skin includes moulded formations 21 which form storage receptacles or boxes or mounts for instrumentation or controls and a rear portion of the moulding includes recesses 22, 23 to receive cab lights or control buttons.
