do not overload your vehicle or trailer. Overloading
can cause poor performance or damage to the brakes,
axle, engine, transaxle, steering, suspension, body
structure or tires.
To reduce potential for drive-line
damage, use low range.
When towing 5th wheel attachments, like a fairway
aerator, always install the “wheely bar”(included with
the 5th wheel kit) to prevent the front wheels from
lifting off the ground if the towed attachments
movement is suddenly impaired.
Remote Hydraulic Control
(Optional)
The remote hydraulic control kit supplies “live”
hydraulic power from the vehicle pump whenever the
engine is running. The power can be used through the
quick couplers at the rear of the vehicle.
Control Lever Positions
1. FLOAT
2. ON
3. OFF
Off Position: This is the normal position for the
control valve when it is not being used. This position
allows the oil leaving the dump valve to flow through
the remote hydraulic valve to the power steering
circuit. In this position the work ports of the control
valve are blocked and any load will be held by the
check valves in both directions.
Raise (Quick Coupler “B” Position): This is the
position that will lift the rear hitch attachment or apply
pressure to quick coupler “B”. This also allows return
oil from quick coupler “A” to flow back into the valve
and then out to the power steering circuit. This is a
momentary position and when the lever is released it
spring returns to the center off position.
Use double acting cylinders only. Using a
single acting cylinder does not allow return flow of
hydraulic oil and makes steering more difficult. Using
a single acting cylinder can lower oil level in transaxle
and cause damage to hydraulic pump and transaxle.
On Position: This position is similar to Raise (quick
coupler “B” position). It also directs oil to quick
coupler “ B” except that the lever is held in this
position by a detent notch in the control panel. This
allows oil to flow continuously to equipment that uses
a hydraulic motor. This position must only be used on
attachments with a hydraulic motor attached.
Note : If hydraulic motor is used, it may see 6900 kPa
(1000 psi) back pressure.
If used with a hydraulic cylinder or no
attachment, the Raise or On position causes the oil
flow to go over a relief valve which can damage the
hydraulic system. Additionally this condition does not
allow return flow to supply the power steering circuit,
which makes steering more difficult. Use these
positions only momentarily or with a motor attached.
Lower (Quick Coupler “A” Position): This position
will lower the rear hitch attachment or apply pressure
to quick coupler “A”. This also allows return oil from
quick coupler “B” to flow back into the valve and then
out to the power steering circuit. This is a momentary
position and when the lever is released it spring
returns to the center off position. Momentarily holding
and then releasing the control lever in this position
will provide flow to quick coupler “A” which provides
power down on the rear hitch. When released, it will
hold the down pressure on the hitch.
If used with a hydraulic cylinder, holding
the control lever in the lower position causes the oil
flow to go over a relief valve which can damage the
hydraulic system.
Float Position: This valve position allows oil to flow
in and out of the work ports and is connected to the
inlet and outlet ports at the same time. This allows for
attachments as the rear hitch to “ float” up and down.
The same pressure is applied to both quick couplers
due to back pressure from the steering circuit.
