INSTALLATION

1. Tractor Preparation: Before attempting to install the
Outback® Hitch, park the tractor on a smooth level floor
with adequate clearance to work around the drawbar area.
Remove any accessories installed on the tractor drawbar
including the hammerstrap clevis and safety chain holder.

If the tractor is equipped with a drop-style drawbar, remove
the drawbar and flip it upside down. Reinstall the drawbar
as shown. The Outback® Hitch requires a minimum
mounting clearance of 14-1/4 in. (362mm) between the
center of the drawpin hole and the rear of the tractor sup­port casting.

2. Determine Proper Mounting Configuration: The
Outback® Hitch is supplied with a universal mounting kit
(packaged in a burlap bag) and includes all necessary hard­ware to mount the hitch to most CAT II or III tractor draw­bars. Not all parts included in the kit are required for each
specific installation.

Carefully review the mounting hardware details shown on
page A7 for your tractor specific mounting configuration.
Identify the required parts as shown.

3. Mounting the Hitch: Using a forklift, floor jack, or
chain hoist, position the Outback® Hitch under the tractor
drawbar as shown. Notice that the hydraulic hoses to the
left cylinder must route over the top of the tractor drawbar.
Center the hitch directly under the tractor drawbar with the
drawpin hole lined up over the center of the corresponding
hitch mounting hole.

4. Install Hammerstrap at Front of Hitch: Insert
mounting bolt (A) into the front slot of the hitch, on both
sides of the drawbar, and install hammerstrap plate (E).
Secure with lock washers (C) and hex nuts (D). Do not
tighten hardware at this time. Slight adjustments of the
hitch forward or backward may be required to install
mounting hardware at the rear of the hitch.

5. Remove Hitch Shipping Pallet: The hitch is secured
to the shipping pallet with two lag screws and washers.
Remove both screws and lower the shipping pallet, allow­ing the hitch to be suspended from the front hammerstrap.

6. Connect Hydraulic Feed Hoses: The hitch hydraulic
supply lines have colored grips. Connect the supply lines
to the tractor remote outlets so that the red grip is pressure
and the black grip is return. During operation the hitch
requires a fixed 1.5 gpm oil flow, up to 3000 psi. Adjust
the tractor remote outlet oil flow to closely match this
requirement.

7. Move Hitch Drawbar Right: Start the tractor and
enable the hitch hydraulic remote outlet. The coils on the
hitch hydraulic control block have manual push button
overrides. Using a small screwdriver or common nail,
push the manual override at the center of the rear coil to
move the hitch drawbar to the far right extent. Disable the
hitch hydraulic remote outlet, and shut off the tractor.

8. Install Mounting Hardware at Rear of Hitch: Add
necessary hitch spacer plates (F) between the hitch and the
tractor drawbar so that the hitch is level. Insert the proper
sized draw pin bushing (G) into the tractor hitch pin hole.
Make certain that the bushing is not longer than the thick­ness of the tractor drawbar. Insert mounting bolts (B) up
from the bottom of the hitch through the top hitch plate,
spacer plates, and draw pin bushing. Install 3/4” thick
spacer plate (F) on top of the tractor drawbar, and secure
with lock washers (C) and hex nuts (D).

9. Move Hitch Drawbar Left: Start the tractor and
enable the hitch hydraulic remote outlet. Push the manual
override at the center of the front coil to move the hitch
drawbar to the far left extent. Disable the hitch hydraulic
remote outlet, and shut off the tractor.

10. Complete the Hitch Mounting: Insert the remaining
mounting bolt (B) up from the bottom of the hitch along
the right side of the tractor drawbar, and secure with lock
washer (C) and hex nut (D). Securely tighten all mounting
hardware (5 places), beginning with the rear center hex nut.
Make certain that the spacer plates tighten uniformly so
that no gaps are observed between the hitch and the tractor
drawbar.

11. Determine Tilt Sensor Location: The tilt sensor
should be mounted directly onto the rear tractor frame in
an area protected from mud and flying debris. The sensor
must be oriented relative to the forward travel direction as
shown on the sensor decal. Orient the sensor with the label
up and the connector towards the rear. The sensor may
require re-orientation onto the sensor bracket to accommo­date mounting directly to the tractor frame.

12. Mounting the Tilt Sensor: The preferred tilt sensor
mounting technique is to locate an extra bolt hole in the
rear tractor casting. The large slot on the sensor mounting
bracket can be slipped under the head of a mounting bolt
(customer supplied) and tightened. Make certain that the
sensor is oriented with the label up, level with the tractor,
and with the connector towards the rear.

13. Routing the Hitch Contol Cable: Route the hitch
control cable up from the drawbar past the tilt sensor and
through the back window of the tractor cab. Install the tilt
sensor cable connection. Secure the control cable with the
tie straps provided. Make certain that the control cable is
clear of any pinch points around the three-point linkage
and is protected from mud and flying debris.

14. Exchange Power Cable: Install the Outback® S,
using the instruction booklet provided. Do not use the
power cable provided with it. Locate the Power/CAN
cable in the Hitch package. It has two connectors and a
cigarette lighter plug. Install the connector with two cables
coming out into the S Power/CAN port as shown. Twist
the connector firmly until it locks into place.

Note: The Outback® Hitch may also be used in com­bination with the optional Outback® 360. If a 360 is
already installed, step 14 is not required as the two­connector Power/CAN cable is installed between the
S and the 360. Instead, a three-connector CAN
expansion cable is installed between the 360 and the
Hitch as described in step 15.

15. Daisy Chain Power Cable: Install the optional
Outback® 360, using the instruction booklet provided.
Locate the CAN expansion cable in the Hitch package. It
has three connectors in a ‘Y’ arrangement with a male and
female connector on one end and a female connector on the
other end. Disconnect the CAN connector from the 360
and insert the ‘Y’ end of the CAN expansion cable as
shown. Twist connectors firmly until they lock into place.

16. Rotate Suction Cup: Remove the Hitch console from
its package, and loosen the center adjusting bolt on the suc­tion cup so the cup can be rotated 180 degrees. This puts
the pump button on top for easy access.

17. Mounting the Console: Find a desirable mounting
location inside the cab and THOROUGHLY clean the
glass. Remove the red cap from the vacuum mount, press
it to the window, and pump the button located on the vacu­um mount. Pump until the red line is no longer visible on
the button. (Check it periodically. If the red line becomes
visible, you may have to pump it a little to maintain suc­tion.) Adjust the display for proper viewing angle.

Note: Do not leave the console unattended for
extended periods of time. If possible, remove the unit
from glass when not in use. Continued exposure to
the elements (such as direct sunlight) can be harmful
to the suction cup.

18. Install CAN Cable: Install the remaining
Power/CAN connector (from either Step 14 or 15) into the
upper CAN port on the Hitch console as shown. Twist
connector firmly until it locks into place. For permanent
installations, we recommend removal of the cigarette
lighter plug and hard wiring the leads to a reliable 12-volt
power supply. The red wire goes to positive and the black
wire to negative.

Note: Cigarette lighter sockets are notorious for inter­mittent power. For maximum portability, install a
female cigarette lighter receptacle wired directly to the
battery for each application. For permanent installa­tion, we recommend wiring directly to the battery.

19. Install Hitch Control Cable: Install the Hitch control
cable connector (from Step 13) into the lower HITCH port
on the Hitch console as shown. Twist the connector firmly
until it locks into place.

20. Install Auxiliary Power Cable: Locate the auxiliary
power cable in the Hitch package. It has a connector on
one end and a pair of ring terminals on the other. Install
the cable connector into the upper right PWR IN port on
the Hitch console as shown. Twist the connector firmly
until it locks into place. Route the auxiliary power cable
directly to the tractor battery. The red wire goes to posi­tive, and the black wire goes to negative.

SETUP

Configuration of the Outback® Hitch is accomplished
through the S, or 360, menu system. During power-up, the
Hitch is detected, and an additional menu option is includ­ed to configure the Hitch for operation.

To access the menu: Press the MENU button. Then
choose the HITCH CALIBRATE item. All functions in the
Outback® S console menu are navigated and selected
using the UP/DOWN ARROWS and the ENTER key.

1. POSITION: This function establishes the relation
between the actual hitch pin position and the measured
position as displayed on the Hitch console. Selecting this
function brings up three successive display screens to cali­brate the left, right, and center hitch pin positions. Use the
LEFT/RIGHT ARROWS on the Hitch console to position
the physical hitch pin at the required location; then press
ENTER to update the calibration values.

2. CURVE: This function adjusts the amount of hitch pin
compensation necessary to match the implement tracks to
the tractor while driving around a curve. Drive the tractor
and implement to an open area which is relatively flat.
Proceed to drive around a large curve (typically 150 foot
radius or more). Observe how the implement is trailing
behind the tractor and use the LEFT/RIGHT ARROWS on
the Hitch console to adjust the hitch pin position so the
implement tracks match those of the tractor. Press ENTER
to update the curvature compensation value.

3. SLOPE: This function enables the Tilt Sensor for side
slope compensation and establishes a level reference value.
Selecting this function first displays an ON/OFF choice
selection. Selecting ON brings up a subsequent display

Follow GPS Mode: This mode causes the hitch to seek
the GPS guideline you are following. For example, if you

drive right of the
guideline, the hitch
will move left to com­pensate.

In follow GPS mode,
use the Outback® S as
normal. You can
establish a guideline
using either straight or
contour guidance.
Simply drive the trac­tor near the guideline,
and the Hitch will
position the hitch pin
directly over the line.

Note: When operating with the Hitch in follow GPS
mode, the Outback® S and 360 use the actual hitch
pin position for contour guidance logging and applica­tion mapping.

OPERATION

GPS Guideline

Hitch positions
implement on
GPS Guideline

Tractor off
to right of
GPS Guideline

Match Tracks Mode: This mode is for driving through
standing crop in side-hills and curves. For example, when
the tractor leans left on a side­hill, the hitch adjusts right so
the implement tires don’t dam­age the crop. The amount of
adjustment is proportional to
the measured tilt of the tractor.
The sensitivity of the slope
compensation may be adjusted
using the LEFT/RIGHT
ARROWS, as you drive
through the standing row crop.

Likewise, when following rows
around a curve to the right, the
hitch adjusts left to minimize
crop damage. The amount of
adjustment is proportional to
the sharpness of the turn. The
sensitivity of the curve compen­sation is adjusted in the HITCH
CALIBRATE setup menu.

Note: When operating with the Hitch in match tracks
mode, the Outback® S displays MATCH TRACKS

The operation of the Outback® Hitch is quite simple.
Turn it on, activate the tractor hydraulics, select the desired
MODE, press RUN, and the rest is automatic.

Note: As a safety feature, the tractor must be travel­ing faster than one mile per hour before the RUN but­ton can enable active hitch control.

Manual Mode: This mode allows the operator to position
the hitch pin at any desired offset using the LEFT/RIGHT
ARROWS. When operating with the Hitch in manual
mode, the Outback® S and 360 operate as normal. All
functions of the S and 360 are affected by the presence of
the hitch.

MAINTENANCE

Proper maintenance of the Outback® Hitch mechanical
components will ensure years of dependable service and
protect your investment.

Initial Installation: After the first few hours of operation,
check the tightness of all Hitch mounting bolts and hard­ware. Substantial wear will occur to the Hitch and tractor
drawbar if mounting bolts are not properly tensioned.

Grease Fittings: Proper lubrication of the 5 grease loca­tions at 12-hour intervals will dramatically prolong the life
of friction production parts. Use an SAE multi-purpose
type grease. Make sure to clean the fittings thoroughly
before using any grease gun.

Replace Worn Components: At the begining of each
application season, check the hitch drawbar for any signs
of free-play, both up and down and side to side. All wear
points of the Hitch include serviceable replacement parts.
Refer to pages A4 and A5 for details.

Problem - Probable Cause. Action

Hitch Drawbar Doesn’t Move

√ Tractor Hydraulics Not Active. Make sure hydraulic hoses are hooked up correctly (red hand grip to pressure;

black hand grip to return). Use push button over-rides on hydraulic block coils to verify operation.

√ Poor Electrical Connection. Check the indicator lights on the hydraulic block coil connectors. If no lights,

check cable connections. If lights show, then replace coil.

Hitch Drawbar Moves in the Wrong Direction

√ Tractor Hydraulics Reversed. Make sure hydraulic hoses are hooked up correctly (red hand grip to pressure;

black hand grip to return).
