Winch Name Plate & Identification Nomenclature
Winch Part Identification
Operation and service of the winch can be explained easier by defining a few major structural
components. (See illustration below for reference.)
Motor – The motor, depending on model, is either electrically (12-volt power) or hydraulically
driven.
Drum – The winch drum is the structural component used to store the wire rope and to transmit
torque from the winch motor and gears to the wire rope.
T o r p e d o H i t c h O p e r a t o r s M a n u a l 9 | P a g e
Drum Supports – Drum supports are the structural components of the winch that mount the
winch to the machine. The drum rotates while being held by the drum supports and both the
motor and gear train are attached to the drum.
Gear Train – This winch is equipped with a planetary style gear set. Planetary winches consist
of a gear train made up of three planetary gear stages (two stage hydraulic winch). The
purpose of the gear train is to multiply motor torque and to reduce motor speed transmitted to
the drum. The gear trains are enclosed in a housing and are lubricated with grease.
Freespool Clutch – A free spool clutch is incorporated in the gear train to allow the user to pull
the wire rope off the drum to the anchor point where the hook will be attached, without using the
winch motor. This is what is referred to as ‘freespooling’.

Winch Overview A winch is a compact device used to pull heavy loads over short distances. The winches load is
provided electrically or hydraulically, depending on model winch, from the tractors supply.
Power feeds from the power source into the winch motor, but first must past either a hydraulic
control valve or electric switch.
Once the winch power source is switched on, the motor begins to turn that energy into
mechanical energy. The motor shaft turns the motor coupler, which, in turn, drives the brake.
On power-in operation, the brake simply rotates and drives the planetary gears, starting with the
gear carrier stage farthest from the winch drum (the first stage carrier). The first stage carrier, in
turn, drives the second stage carrier, which then drives the third stage carrier. The third stage
directly drives the drum. Since the wire rope is connected to the drum, the rope winds around
the drum, causing the load to be drawn in.
On power-out operation, the motor is reversed and the winch drum is rotated in the opposite
direction. All winch components operate in the same manner as during power-in except the
brake. During power-out, the load tries to ‘over-speed’ the motor (make the motor turn faster
than it would under its own power). When the brake detects this over speed it engages just
enough to make the load and motor run at the same speed and slow the load. When the power
sourced is switch off, the brake engages and completely stops the load.

Working Conditions
The operator should always practice safety. Operate the winch from a safe
position when pulling a load. Stay clear of any obstruction. Keep away from
the moving object. Operator should stand perpendicular to the wire rope at all
times and NEVER in-line with the wire rope in case of accident. The safe
position will help prevent the wire rope from hitting an operator if the wire was
to fail under extreme load.
If the winch is equipped with a remote control (electric only), operate the
winch with the remote control cord fully extended whenever possible. The
operator should be at least 8 feet from the winch while in operation. This will
prevent entanglement of the cord with the winch and help keep operator out
of harm’s way.
Cleaning
Do not use steam or high pressure water to clean the winch. Use of low
pressure water and mild soap with a rag to clean the winch is best
recommended. Avoid using chemicals that may damage the unit.
Thoroughly clean all corrosive materials from the winch as soon as possible
to minimize deterioration, rust deposit and mineral build-up.
Maintenance
No lubrication is required for the life of the winch unless the winch has been
submerged in water. If this occurs, it is best recommended to have the unit
serviced at a qualified service center as soon as possible to prevent corrosion
damage. If this is an electric winch, and the control pack was submerged in
water, it may need to be replaced. Check the battery cables and connections
at 90 day intervals to be certain they are clean and tight. Spray electrical
connections with an anti-corrosive spray. On hydraulic winches, be sure all
hoses fittings are tights and are not leaking. Inspect the wire rope before and
after each use. If damaged, replace with the size specified in the
Specifications. If replaced, the wire rope must be spooled onto the drum in
the rotation specified and by the decal noted on the winch.
For further assistance with the Torpedo Winch, contact your local authorized
HORSCH dealer.

Operation Follow all safety guideline posted above and be aware of all warnings and cautions during
operation.
Hydraulic
Either a single, or a dual winch Torpedo Hitch can be installed on most machines. Most
typically the machines are equipped with a hydraulic Series 9 winch. In the diagrams below you
will see how they are installed in the hydraulic system.

T o r p e d o H i t c h O p e r a t o r s M a n u a l 23 | P a g e
In a hydraulic system, to activate the Torpedo Winch, the Selector Valve (1) shown must be
open to release pressure and hydraulic flow to the check valves and then to the Spool Valve(s).
Each winch is operated by a separate spool valve lever.
Switch the Selector valve to winch mode. Then activate the tractor control valve. Allow the
tractor to run at about half RPM speed. With the tractor running, and the valves in the correct
position, you can begin winching using the spool valve levers.
Release the free spool lever on the winch and unpin the Torpedo from the hitch by removing the
hitch pin with lanyard and cotter pin. Pull out the cable with attached Torpedo drawbar.
Connect the Torpedo drawbar to the hitch of the implement or whatever you plan on towing.
Standing clear of any obstruction and perpendicular to the wire rope, activate the spool lever to
begin winching and pulling in the load. Once the Torpedo drawbar has reached the hitch plate
of the winch, release the spool lever, insert the hitch pin and secure it with the cotter pin. Attach
safety chains of the implement to the Torpedo Hitch plate attaching points, illustrated on page 8.
Repeat procedure for Dual Torpedo Hitch configuration. (Dual Torpedo Hitch has a double
hydraulic spool valve for individual operation of each winch – shown below.)

Electric
Connect the power source to the winch.
Electrical Connections
Use included insulating boots to cover exposed connections to prevent from
electrical shorting. Route battery cables in areas which will not cause harm to
them to prevent potential short circuits.
A fully charged battery and good connections are essential for proper
operation of the winch. The electric winch from HORSCH operates from a
12-volt DC power source. The minimum requirement is 12-Volt DC battery,
650 Cold Cranking Amps (CCA).
See the diagram and information below for reference in connecting your
winch.
T o r p e d o H i t c h O p e r a t o r s M a n u a l 25 | P a g e
When using an electric winch, be sure the unit has power connected from a power source on
the tractor. Connect the remote control cord to the outlet of the winch. Then release the free
spool lever on the winch and unpin the Torpedo from the hitch by removing the hitch pin with
lanyard and cotter pin. Pull out the cable with attached Torpedo drawbar. Connect the Torpedo
drawbar to the hitch of the implement or whatever you plan on towing. Standing clear of any
obstruction and perpendicular to the wire rope, activate the remote control by pressing the
switch to begin winching and pulling in the load. Once the Torpedo drawbar has reached the
hitch plate of the winch, release the remote switch of the control, insert the hitch pin and secure
it with the cotter pin. Attach safety chains of the implement to the Torpedo Hitch plate attaching
points, illustrated on page 8.
NOTE: Do not leave the remote plugged in to the winch when not in use. Leaving the
remote plugged in could cause an accident if triggered or a battery drain, if not
disconnected.
General Operation
Clutch Operation
When the clutch is engaged, the gear train is coupled to the drum and power is transferred from
the motor. When the clutch is disengaged, it is in the free spool position and the gear train and
wire rope drum are uncoupled allowing the drum to rotate freely. The clutch lever, located on
the winch housing opposite of the motor side, controls the clutch position. To prevent damage,
always fully engage or fully disengage the clutch lever.
Spooling Out
Freespooling is generally the quickest and easiest way to spool out wire to the implement. Use
the power of the winch to let out a few inches of wire that may be under load. This will make it
easier to remove the hitch pin if there is any binding. Be sure to disconnect power from the
winch before beginning freespooling. Disengage the clutch. Freespool manually by hand,
(Viewed from top)
26 | P a g e T o r p e d o H i t c h O p e r a t o r s M a n u a l
pulling on the torpedo, releasing wire from the winch. When freespooling, it is best
recommended to leave a minimum of 5 wraps of wire around the drum.
Spooling In Under Load
Never exceed the winches rated line pull as noted in Specifications. Power in the wire evenly
and tightly to the drum. Equal amount of tension is best if possible. Avoid shock loads by
pulsing the power to take up any slack in the wire.
CAUTION! Shock loads can exceed the winch and the wire rope maximum ratings.
Spooling In Under No Load
When spooling in the wire with no load or tension, it is best recommended to simulate a load or
create some tension to spool tightly to the drum. Using an assistant may help by holding the
wire and keeping constant tension if possible. If you are alone, arrange the wire so it will not
kink or tangle when it is spooled. Be sure any wire rope currently spooled on the drum is
already tight and evenly layered. Spool enough wire to complete the next layer on the drum.
Tighten and straighten the layer. Continue and repeat until the wire is fully retracted and
spooled onto the drum of the winch.
Overloading
The winch is rated for intermittent duty. When the motor approaches stall speed, very rapid
heat buildup occurs which may cause motor damage. Double-line rigging can reduce the
amperage draw and reduce heat buildup in the motor. This would allow longer continual use.
Unfortunately, double-line rigging isn’t possible with how the Torpedo Hitch is designed. It is
always best to know the limitations of the winch and the implement you plan to tow.
Stretching Wire
Exercise care and routine maintenance with your winch and wire rope. The life of the wire rope
is directly related to the use and the care it receives. During its first use, a new wire rope should
be spooled onto its drum under a minimum load of 1000lbs.
1. Find a flat, level surface to park the machine with adequate space to unspool the entire
length of the wire rope.
2. Turn the clutch lever to free spool the wire. Spool out the wire except for the last few
turns of the wire from the drum. Once spooled out, turn the clutch lever on the winch to
the engaged position.
3. Attach the Torpedo end of the wire to an anchor point. Then move the equipment the
winch is attached to forward until the wire is taught, with very little slack. Be sure to take
the tractor out of gear and set it to Park. Set the brake.
4. If using an electric winch, connect the remote control. If using a hydraulic winch, turn on
the main selector valve and/or check valve. Now apply power with the remote switch or
the spool valve lever and slowly retract the winch until all of the slack is wound onto the
drum. Turn off the remote switch or spool valve lever. Hold tension on the wire with one
hand; carefully push the wire to the side of the drum the wire is attached to so there are
no gaps between each coil on the drum. (Be sure to check that the wire is winding off of
T o r p e d o H i t c h O p e r a t o r s M a n u a l 27 | P a g e
the bottom of the drum, not the top, or the automatic load holding brake will not function
properly.)
NOTE: If the wire rope is winding off the top of the drum, you have powered the
winch ‘out’ instead of ‘in’ and now have reverse clocked the wire to the drum.
5. It is recommended to use two people as noted above in ‘Spooling In Under No Load’.
Tensioning the wire is critical to ensure longer life. Tensioning will also prevent outer
layers of wire rope from pinching and deforming the inner layers, keeping everything
nicely aligned and in good condition, preventing damage to the wire.
6. Apply power to the winch. With the wire pulled to the side as instructed in step 4 above,
and tension applied, retract the wire. After winching approximately 6 feet, stop and
check to see that the wire is spooling evenly on the drum as it should. If the wire is
uneven or sinking into a lower layer, reverse the wire out a few feet and retry.
HINT: You may need to apply more weight or higher pressure if the wire is sinking
into a lower layer. Wire sinking into lower layers indicates a loose spool on the
drum and needs to be winched tighter.
* Viewed from the back side of the Torpedo Hitch.
7. Once the wire is spooling correctly, continue winching until the torpedo drawbar just
enters the hitch. Then switch off power. Align the pin holes of the drawbar and hitch
and install the hitch pin and cotter pin.
8. Repeat the procedure above if the wire around the spool still appears loose.
