Auxiliary Lift Cylinder Lock-Out Valves
To prevent unintended header movement, engage the auxiliary lift cylinder lock-out valves before disconnecting, servicing,
or transporting your machine. The lock-out valves are located on the auxiliary lift cylinders at the back of the header.
3.2.1
Locking and Unlocking Auxiliary Lift Cylinders
The auxiliary lift cylinders provide additional lift range when raising the 3-point hitch.
Auxiliary lift cylinders at both ends of the header use a shut-off valve to prevent movement during transport, service, or
when disconnecting from the tractor. When operating in the field, the shut-off valves must be open for header raise and
lower functions to work correctly.
