Solenoid Control
Refer to “Solenoid Control” on page 19 for assembly
and set-up instructions.
Solenoid Plumbing
The flow control valve diverts excess oil back to the
tractor. It is important to know the tractor’s rated GPM
flow (15 GPM & under or 16 GPM and above) and to
plumb the flow control valve accordingly. For a detailed
description of plumbing, see Flow Control Valve
Plumbing on page 21.
Float Control Valve (15 GPM & Under)
Refer to Figure 6-3:
This arrangement requires a check valve between the
tee and return line. Make certain the check valve is
plumbed correctly so that oil can flow towards the tee
fitting in the direction shown by the arrow. Make sure the
lines connected between the tractor and flow control
valve are set-up to flow oil in the direction shown by the
arrows.
Float Control Valve (16 GPM & Above)
Refer to Figure 6-4:
This arrangement requires a return to tractor sump line.
Make certain all three lines connected to the tractor flow
oil in the direction shown by the arrows.
Hydraulic Cylinder Plumbing
Refer to Figure 6-5:
Make sure “ARM 1”, “ARM 2”, and “Deck Pivot” cylinders
are plumbed to ports (SA, SB, SC, SD, SE, and SF) at the
solenoid control box as shown.
