Cleanliness around all hydraulic components is of utmost
importance. Before starting any repair procedures, be sure
to thoroughly clean the parts to be removed, as well as ad-
jacent areas on the tractor, to avoid entry of dirt into the
winch and winch control system. Do not leave any ports
or access openings exposed to the weather. Seal or cap
the openings to prevent entry of dust, moisture, or other
foreign material. Cap or plug all exposed hydraulic ports
and fi ttings.
During disassembly, care should be taken not to damage
seals and O-rings that are to be reused. Replace any such
parts that are damaged or otherwise defective. Certain
O-rings and seals specifi ed in the replacement instruc-
tions must not be reused. In general, seals and O-rings
that work under full operating hydraulic pressures, or that
require extensive disassembly to access, should be re-
placed with new parts at the time of reassembly.
WINCH REMOVAL
Place the tractor and winch in a level position and drain
the oil from the winch into a suitable container. Install the
drain plug securely after the oil has drained completely.
Support the winch with a suitable hoist or platform, and
remove the fasteners securing the winch to the tractor
mounting brackets, then carefully move the winch away
from the tractor so the hydraulic hoses can be discon-
nected.
Remove the hydraulic hoses from the winch motor and
valve. Remove the motor case drain hose from the motor.
WINCH INSTALLATION
Remove dirt, paint and rust from the mounting surfaces of
the winch and tractor mounting brackets.
Attach the winch control hoses to the motor as defi ned in
the parts and installation guide.
Align the winch mounting holes with the holes in the mount-
ing brackets, and install and tighten all fasteners to the rec-
ommended torque. Refer to the winch parts and installa-
tion guide.
Fill the winch to the proper level with the recommended
oil.
NOTE:
It may be necessary to fi ll the motor case with
hydraulic oil before start-up to protect against motor
failure due to starting dry.
Start the tractor engine and operate the engine at low
RPM. Alternately place the winch control in the REEL-IN
and REEL-OUT positions until the winch motor hydraulic
circuit is fi lled with oil and the winch operates smoothly.
Check the tractor hydraulic oil reservoir level and fi ll as re-
quired.
Before servicing, make sure any trapped oil pressure
in the tractor hydraulic system has been relieved. Per-
sonal injury can result from a sudden release of oil pres-
sure. Relieve trapped pressure by cycling the blade
and winch control levers several times after the trac-
tor engine has been turned off. Relieve any trapped oil
pressure in the hydraulic reservoir by opening the cap.
Ensure that the tractor’s master electrical circuit switch
is off.
Hot oil can cause injury. Make certain the oil has cooled
to a safe temperature (less than 110°F or 43°C) before
servicing the winch.
The H50VS winch weighs approximately 1,400 lbs.
(635 kg) without oil, cable and tractor mounting brack-
ets. Make certain the lifting equipment has adequate
capacity. Attempting to lift the winch with undersized
equipment can result in serious injury or damage to the
winch or other property.
