A controller drives a shifting actuator to move a first engagement member from an original position of a first engagement portion in one direction along a relative motion path and acquires first position information representing a first position, the first position being a position where the first engagement portion moved in the one direction contacts a second engagement portion. The controller drives the shifting actuator to move the first engagement member from the original position in the other direction along the relative motion path and acquires second position information representing a second position where the first engagement portion moved in the other direction contacts the second engagement portion. The controller calculates a center position of the first engagement portion on the relative motion path from the acquired first position information and the acquired second position information, compares the calculated center position to the original position.

A system and method using a mount assembly for attaching a powertrain to a structural member of a vehicle. The mount assembly includes a first compliant member, a second compliant member, a first fluid chamber, a second fluid chamber, a third fluid chamber, a pressure compliant membrane, and a valve. A fluid conduit interconnects the first fluid chamber with the second fluid chamber to allow a fluid to pass from the first fluid chamber to the second fluid chamber. The third fluid chamber has an opening in communication with the second fluid chamber and a vent port. The pressure compliant membrane seals the opening between the second fluid chamber and the third fluid chamber. The valve selectively seals the vent port in the third fluid chamber. A first stiffness profile of the mount assembly is selected by actuating the valve to open the vent port. A second stiffness profile of the mount assembly is selected by actuating the valve to close the vent port.

A rough terrain cart for a wheel chair includes a frame operable to support a wheel chair and a wheel chair user. A pair of cart drive wheels are rotationally mounted to the frame. A locking mechanism is engaged with the frame. The locking mechanism is operable to secure the wheel chair to the cart. A rotational mechanism is engaged with the frame. The rotational mechanism is configured to support a pair of wheel chair drive wheels of the wheel chair and is operable to enable the wheel chair drive wheels to rotate when the wheel chair is secured to the cart by the locking mechanism. A transmission system is engaged with the frame. The transmission system is connectable to the wheel chair drive wheels. The transmission system is operable to transmit torque from the wheel chair drive wheels to the cart drive wheels.

A work vehicle includes an engine and a belt-type continuously variable transmission device provided on a lateral side of the engine and configured to (i) receive power from the engine and (ii) output the power to a traveling device while varying the power in terms of speed. The belt-type continuously variable transmission device has (i) an intake port which is present in the transmission device case and through which cooling air is sucked from outside the transmission device case into the transmission device case as a result of rotation of the rotary fan and (ii) a first exhaust port which is present in the transmission device case and through which the cooling air is discharged from inside the transmission device case as a result of the rotation of the rotary fan. The first exhaust port is present on a side of the exhaust pipe on which side the engine is present, and faces the engine.

A vehicle shown herein is a side by side utility vehicle having a powertrain an engine with at least three cylinders, an intake and an exhaust, where the intake is forward of the engine and the exhaust is rearward of the engine. The vehicle may further or alternatively include an engine block configured to couple with various transmissions without alteration of the engine block itself.
