An assembly for reversing a fluid driven motor. The assembly includes a fluid driven motor, and a reversing valve that reverses inlet and exhaust porting to and from the fluid driven motor. An actuation device opens an actuation valve and a fluid supply valve. The actuation valve causes the reversing valve to reverse the inlet and exhaust porting to and from the fluid driven motor when the actuation device opens the actuation valve. The fluid supply valve allows fluid to flow through the fluid supply valve to the motor when the actuation device opens the fluid supply valve. The fluid supply valve also prevents fluid flow through the fluid supply valve to the fluid driven motor when the fluid supply valve is closed.

[What is claimed is:] [1.]a fluid driven motor;a throttle valve in communication with a primary fluid flow supply channel located upstream of said throttle valve with respect to a direction of fluid flow, said throttle valve being openable and closeable, said throttle valve for directing fluid flow to said motor from said primary fluid flow supply channel to rotate said motor in a forward direction when said throttle valve is opened;a reversing valve; andan actuation valve for causing said reversing valve to reverse an inlet port to said motor and an exhaust port from said motor when said actuation valve is actuated, said actuation valve being in communication with said primary fluid supply channel at a location upstream of said throttle valve. [3.]opening a first valve to operatively connect the fluid supply channel with the second fluid passageway in response to a lever being moved by the user; andopening a second valve to supply fluid flow from the fluid supply channel to the second fluid passageway to turn the fluid driven motor in reverse in response to said lever being moved by the user.
