Connecting Cylinders To
Tractor Control Valve for Hydraulic Supply.
When the tractor hydraulics are
used to supply and operate the cylinders
there will not be a control valve shipped
with the mower. The hydraulic cylinders
will connect direct to the tractors remote
outlets and the tractor controls will be
used (See Figure 14).
When using the Auxiliary front
pump for the cylinder hydraulic system
there will be a control valve and components shipped. See the section for installing the auxiliary pump and control valve.
