Adjusting Cutting Unit Lift and
Drop
The cutting unit lift/drop circuit is equipped with a
flow control valve. This valve is preset at the factory at
approximately 3-1/2 turns open, but an adjustment may
be required to compensate for differences in hydraulic
oil temperatures, mowing speeds, etc. If an adjustment
is required, proceed as follows:
Note: Allow the hydraulic oil to reach full operating
temperature before adjusting the flow control valve.
1. Raise the seat and locate the flow control valve
mounted to the main control valve (Figure 46).
