Safety Information

!

As the manufacturer of your Outback Hitch Drawbar

Implement Guidance System, we care about your safety. In

fact, this machine and its systems have been designed to

provide maximum safety. Unfortunately, no machine

design can prevent operator error or carelessness.

This operator’s manual provides instructions for the

safe operation and maintenance of the OutbackHitch.

Please read and understand this manual before operating

the machine.

DO NOT Use with PTO Drive-line Powered Equipment. A tractor­mounted PTO drive shaft is not designed for use with a swinging drawbar

extender, such as the Outback



Hitch.

WARNING:

!

DO NOT Exceed Weight Limits. Review tractor specific limits for drawbar

extender application. The maximum vertical static load is 4000 lbs. (1800 kg).

WARNING:

!

HIGH-PRESSURE FLUID HAZARD. The Hitch utilizes hydraulic compo-

nents. Always relieve pressure on the system before repairing or adjusting. To
avoid hazard, wear proper hand and eye protection, and keep in good repair.

WARNING:

!

MOVING PARTS HAZARD. To avoid injury, keep hands and fingers

away from the swinging Hitch drawbar area.

WARNING:

!

ALWAYS Attach Safety Chain Between Tractor and Implement.

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.
