Abstract
A control system for a fluid activated clutch which includes a shut-off valve and a manually operable control lever connected to a control valve. A quantity of fluid retained in a fluid reservoir is pressurized by a pump and fluidly supplied to the clutch by fluid passages which interconnect the two valves. Movement of the control lever activates the control valve and allows pressurized fluid to control the position of the shut-off valve. After the fluid has been pressurized, the shut-off valve functions to prevent the clutch from being engaged by the pressurized fluid until the control lever has been depressed once and then released.
