Hydraulic System Function
General
All of the inboard and auxiliary hydraulics are controlled by
the attachment lift control lever. The attachment lift control
lever raises and lowers attachments that utilize the tractor’s
hydraulic lift cylinder. This lever also controls attachments
that use the tractor’s auxiliary hydraulics via the quick
couplers on the front left and right sides of the frame.
The rate of hydraulic fluid flow and pressure that are
available when using the auxiliary hydraulic quick couplers
is listed in the chart in Figure 8.
The lever has five positions: left, right, back, forward (first
detent) and float (pushed forward to second detent).
