Preparation and Setup
1. Shut down tractor before making any hydraulic
connections. A Power-Beyond connection cannot be
made while hydraulics are live.
2. Connect the steering/fan case drain line first,
before making any other connections. Connect this
line to a low pressure drain port.
Case drain hose has the smaller
1
/
4
inch I.D. hose
and small, flat-face, connector.
Machine Damage Risk:
DO NOT connect the fan/steering case drain line to a
power-beyond-port. Case Drain Hose must be attached first,
prior to inlet and return hoses being connected. Case Drain
Hose must be detached last, to prevent damage to the fan
motor.
3. Connect the load-sense line second. Connect this
to the load-sense port associated with the
power-beyond port pair to be used for steering. This
line is provisioned with a very small QD-style
connector.
4. Connect the steering/fan circuit low pressure return
hose third. This hose is connected to a tee at
the control valve. Connect this hose to a low
pressure return connector.
Steering/fan pressure return hose has a large
(1.06 inch / 2.7 cm diameter) quick coupler.
5. Connect the steering circuit high pressure hose
fourth. Connect this hose to the pressure side of the
Power-Beyond port.
6. Connect the fan motor pressure hose fifth. If the
tractor has a priority remote, use it for the fan
connection.
7. Connect the remaining circuits to tractor remotes:
•
Lift (Standard) / Down Pressure (Option)
•
Wing (Standard) / Marker (Option)
•
Hydraulic Drive (Option)
Machine Damage Risk:
Steering system hoses must be connected, or casters may
remain locked at their last used orientation. If casters cannot
steer or float, any attempt at movement may cause damage. If
steering hoses cannot be connected, also leave the steering
system off, and make only careful forward moves.
