<p>A hydraulic motor bypass apparatus is disclosed comprising a power source; a fluid circuit having a fluid reservoir, a fluid operated motor, means for pumping fluid from the reservoir to the motor, the pumping means powered by the power source, a speed control valve connected in the circuit and a motor bypass valve connected, in the circuit. A feed table is driven by the fluid motor and a drive member is rotatably actuated and deactuated by a centrifugal clutch, the drive member being powered by the power source. A shaft extends through the bypass valve and a driven member is connected to be rotatably driven on the shaft by the drive member, the driven member being connected for rotating the shaft to a position for blocking fluid flow through the bypass valve. The shaft can be rotated to a position for opening fluid flow through the valve for bypassing the motor. ::</p> |
