USING REMOTE HYDRAULICS
The tractor is equipped with a remote hydraulic
system for powering hydraulically driven implements
that are approved for usage on the tractor.
WARNING: To avoid personal injury, stop
the tractor engine and relieve pressure
from the hydraulic system before
connecting or disconnecting lines. Do
not use your hand to check for leaks.
Connecting Implements
Clean the hydraulic couplers on both the tractor
and implement.
Remove dust plugs or caps from the couplers.
Refer to Figure 39.
Figure 39
Insert the implement coupler into the tractor
hydraulic coupler.
Pull slightly on the implement couplers to make
certain they are firmly connected to the tractor.
Disconnecting Implements
Lower the implement to the ground to release
hydraulic pressure in the hoses.
Relieve pressure by moving the hydraulic control
lever in each direction several times with the
engine shut off.
Pull each implement hose coupler straight from
the hydraulic coupler to release it.
Clean oil and dust from each coupler and replace
the dust plugs and/or caps.
Remote Control Valve Lever
Move the lever up or down and hold. This will raise or
lower the implement. The lever will return to neutral
when released.
IMPORTANT: Do not hold the lever in the "pull" or
"push" position once the remote cylinder has reached
the end of its stroke. Doing so will force oil through
the relief valve, and over a prolonged period cause
the hydraulic oil to overheat.
IMPORTANT: When using the tractor hydraulic
system to power a front loader, do not operate the
boom and bucket cylinders simultaneously.
TRACTOR WEIGHTING
When implements are installed on either the front or
rear of a tractor, the tractor’s normal balance is altered.
As a rear mounted implement is raised to the
transport position, the balance point of the tractor
shifts rearward, which may result in a loss of
steering control and tractor stability.
When a front mounted implement is raised, the
balance point shifts forward and may result in a
loss of traction and stability.
To counterbalance these weight shifts, weight should
be added to the tractor in the form of cast iron
weights or liquid ballast. However, only enough
weight should be added to obtain good traction, con-
trol, and stability. Excessive weight will unnecessarily
load down the tractor’s engine and transmission.
NOTE: When adding weight to the tractor, it may be
necessary to increase inflation pressure in the tires.
Front Weights
To counterbalance three point hitch mounted
equipment, weight should be added to the front of the
tractor. Add enough ballast to maintain steering
control and prevent tip over. Remove the weight
when it is not needed. Front weights are available at
your Cub Cadet dealer.
Follow the guidelines provided in the implement
Operator’s Manual to determine how much weight is
needed to counterbalance the equipment. If
guidelines are not available, ballast the tractor so that
a minimum of approximately 40% of the machine
weight is on the front wheels.
If necessary, contact your Cub Cadet dealer for help
in determining how much weight is needed for your
particular application.
Weighting the Rear of the Tractor
Add weight to the rear wheels if needed to improve
traction or for stability. The amount of rear ballast
should be matched to the job, and the ballast should
be removed when it is not needed. The most common
methods of adding weight are filling the rear wheels
with liquid ballast or mounting a rear weight box.
Liquid Ballast
Because special equipment and a familiarity with the
practice is required, only a qualified tire technician
should perform this procedure. Consult with your Cub
Cadet dealer about having liquid ballast added to
your tires, and for any special maintenance
instructions after the procedure is performed.
Rear Weight Box
Consult with your Cub Cadet dealer about available
rear weight boxes. Your dealer can help in
determining the positioning of the box and the amount
of weight needed for your particular application.
