Hydraulic System Operation
All of the inboard and auxiliary hydraulics are controlled
by the attachment lift control lever, which raises and
lowers attachments connected to the tractor's hydraulic lift
cylinder. This lever also controls attachments connected
to the auxiliary hydraulics via the quick couplers on the
front left and right sides of the frame. The lever has five
positions: left, right, back, forward (first detent) and float
(pushed forward to second detent).
Using Inboard Hydraulics
The inboard hydraulics control the mower deck and 3-Point
Hitch (if equipped). The front / rear hydraulic selector switch
must be in the REAR position.
Pulling the lever back (A, Figure 11) raises the attachment
lift. Pushing the lever forward (B) to the first detent lowers
the attachment lift. Pushing the lever forward to the second
detent locks the control in "float" position, allowing the lift
mechanism to float up and down.
Figure 11
Using Auxiliary Hydraulics
The attachment lift control lever is also used to operate
attachments that use the auxiliary hydraulic couplers
located on the right and left front frame rails. The front / rear
hydraulic selector switch must be in the FRONT position.

Pulling the lever back (C, Figure 12) raises the attachment
lift. Pushing the lever forward (D) to the first detent lowers
the attachment lift. Pushing the lever forward to the second
detent locks the control in "float" position, allowing the lift
mechanism to float up and down.

Moving the control lever to the left (E, Figure 13) angles
the attachment left. Moving the lever right angles the
attachment right.
Many approved attachments have color coded couplers
(F, Blue/Red) and (G, Green/Yellow) to aid in installation.
Match the tractor coupler with the like colored attachment
coupler.
