We need to call this the LOCK-IN VALVE because it
locks fluid IN the hydraulic cylinder!
The original application of the
"Rear Lockout Valve" on 316 - 332 John Deere garden tractors aimed to
speed up application of pressure to the actuator plugged into the shared
hydraulic control circuit. The snow blower and 54 blade angle are two examples.
While the valve works very well in this application, many customers intend the
lockout valve to actually "Lock" a heavily loaded three point hitch
into position. The valve works okay most times but not always. It doesn't
always work because the OEM installation requires the valve be installed on the
wrong side of the hydraulic cylinder.
The Aux-Hyd Positive Rear Lockout Valve
Kit allows the lockout valve to be installed on the correct side of the
hydraulic cylinder. The valve will now hold hydraulic fluid in the cylinder
when high down force is applied. As we remember, a liquid cannot be compressed
but it can be pulled apart.
*** Already have the valve, and just
need the hoses and tube? Now you can select the Hoses + Tube option!
