Abstract: A controller for use with a machine comprising a machine body, and a load handling apparatus coupled to the machine body and moveable by a movement actuator with respect to the machine body, the controller being configured to receive a signal representative of the position of the load handling apparatus with respect to the machine body and a signal representative of a moment of tilt of the machine, wherein the controller is further configured to issue a signal for use by an element of the machine including the movement actuator, which in response to the signal issued by the controller, is configured to restrict or substantially prevent a movement of the load handling apparatus when a value of the signal representative of the moment of tilt reaches a threshold value, the threshold value being dependent on the signal representative of the position of the load handling apparatus with respect to the machine body.

Abstract: A transmission for a vehicle which includes a ground engaging structure driven from an output member of the transmission is disclosed, the transmission including a first input member connected to a prime mover, and a second input member drivable by the operation of a hydraulic drive motor, and the transmission being operable to transmit drive from the first input member to the output member in mechanical drive mode, and from the second input member to the output member in hydrostatic drive mode, the first input member providing a drive input from the prime mover to a mechanical drive train which includes a gear ratio selection apparatus, and for mechanical drive mode, the gear ratio selection apparatus providing for one of a plurality of alternative gear ratios to be selected by the engagement and/or disengagement of at least one power-shift clutch device, and the second input member being connected via a drive path to the output member, and there being a power-shift clutch device between the hydraulic drive
