Bolt Torque Specications
TIGHTENING WHEEL NUTS: Torque 9/16”-18 lug nuts on wheels to 170 ft-lbs during initial operation of the header wagon. Check
for proper torque after every 10 hours of use. Failure to do so may damage wheel nut seats. Once seats are damaged it will become
impossible to keep nuts tight.
Always tighten hardware to these values unless a dierent torque or tightening procedure is listed for specic application. Fasteners must
always be replaced with the same grade as specied in the manual parts list. Always use the proper tool for tightening hardware. Make
sure fastener threads are clean and you start thread engagement properly. Use these values when tightening all bolts and nuts with
the exception of wheel nuts.

Operations/Maintenance
DANGER: BE CERTAIN THAT ALL POWER IS SHUT OFF BEFORE SERVICING THE 4 WHEEL STEER HEADER TRANSPORT.
Before the Header Transport is Put into Service:
• Has the Slow-Moving Vehicle sign been properly positioned at the rear of the header transport?
• Have all danger, warning, caution and important signs on the equipment been read and understood? If employees or others use or
are near this equipment, make sure that they also have read and understood all danger, warning, caution and
important signs on the equipment and have also read the operator’s manual.
• Are all braces, bolts, nuts, studs and lug nuts properly fastened?
• Has the header transport been properly fastened to the towing unit? Use a good quality hitch pin with clip and safety chains.
• Are the rear amber extremity lights properly positioned? Extend lights within 16”of the left and right extremities of the header.
• Check alignment of tires yearly. Adjust the push pull rod to realign the tires if needed.
Safety Chain User Instructions
• Secure the safety chain by looping it around the tongue support located on the underside of the hitch tongue and connect to the
towing machine’s attaching bar.
• Do not allow more slack than necessary for articulation.
• Do not use an intermediate support as the attaching point.
• Store the safety chain by securing it around the tongue.
• Replace the safety chain if one or more links or end ttings are broken, stretched or otherwise damaged or deformed.
Operating Instructions/Maintenance
• Adjust the brackets on the header transport to best t your make and model header.
Note: When mounting the header, NEVER position yourself under or near the header. Securely fasten the header to the
header transport.
• Do not exceed the load and size limits of the unit.
• Keep the tires properly inated. Both under ination and over ination can greatly reduce tire life. Inate 235-85 R16 tires to 80 psi.
• Inspect bracing and welds periodically and repair immediately, if needed. Failure to repair could cause extensive damage and
greatly reduce the life of the unit.
• Repack the bearings in the hub assembly once a year or as needed. Use a good quality LS EP2 severe duty, high shock load, lithium-
based grease.
• Check the wheel nuts often and keep them properly tightened.
WARNING: Check safety chains for broken, stretched or damaged link or end ttings. Replace chains if found to be
damaged. Do not weld safety chains.
Braking System Requirements
• Stopping distance increases with speed and weight of towed loads and on slopes. Towed loads with or without brakes that are too
heavy for the tractor or are towed too fast can cause loss of control. Consider the total weight of the equipment and its load.
Note: Observe these recommended maximum road speeds, or local speed limits which may be lower.
• If towed equipment does not have brakes, do not travel more than 20 mph (32 km/h) and do not tow loads more than 1.5 times the
tractor weight.
• If towed equipment does have brakes, do not travel more than 25 mph (40 km/h) and do not tow loads more than 4.5 times the trac-
tor weight.
• Ensure the load does not exceed the recommended weight ratio. Use additional caution when towing loads under adverse surface
conditions, when turning, and on inclines.
DANGER: Tow loads safely.

11
Operations/Maintenance
Adjusting Push-Pull Rod to Align Front and Rear Axles
Before initial operation of header transport, follow these steps to align front and rear wheels while under load:
1. With the transport empty, loosen both nuts on the push-pull rod. The push-pull rod is left hand threaded on
one end and right hand threaded on the other end to adjust alignment like a turnbuckle. One of the nuts is
pictured in blue in the diagram below.
2. Place combine header on transport.
3. Drive the loaded transport in a straight line on level ground to check alignment.
4. Adjust push-pull rod by rotating the main rod body.
5. Repeat steps 3 and 4 until the transport rear wheels are aligned with front wheels.
6. Remove combine header from transport.
7. With the transport empty, tighten both nuts on the push-pull rod.
8. Return the combine header to the transport.
9. With the nuts on the push-pull rod tightened, drive loaded transport in a straight line on level ground to
conrm alignment.

Set-Up Instructions
Mounting the Front and Rear axles
• Set both of the bottom frame bars on two sawhorses or blocks.
NOTE: Place 4” blocks under the small lower bar so the ends are level. The small lower bar is the bar without the truss
picutured below.
Non-Trussed Lower Bar
• Attach the front and rear axles to the frame bar using (8) 5/8”x 6” hex bolts, (8) 5/8” centerlock hex nuts and (2) frame tube end
plates. Tighten all hex nuts.
• If your header transport includes the optional spare tire mount, the spare tire mount replaces the rear frame tube end plate.
Trussed Lower Bar
• Attach the front and rear axles to the frame bar using the wing saddle lower bases, (8) 5/8”x 6” hex bolts, and (8) 5/8”centerlock
hex nuts. The U-bolt and (2) 5/8”centerlock hex nuts need to be tightened. Picture is shown on the bottom right hand corner of
this page.

• Before installing the tie rod, slide the two center support brackets pictured below onto the bar. Slide the larger brace towards the
rear of the header transport and the smaller brace towards the front. Insert the guide blocks and secure using the original hardware.
While inserting the guide blocks, ensure all holes line up. The guide blocks are two dierent parts and must line up correctly.
• Adjust both clevis ends so that the holes in the clevis ends line up with the holes in the hitch top plate.
• Use (2) 3/4”shoulder bolts and (2) 3/4” shoulder bolt nuts to attach both ends of the push pull rod.
