Safety Rules
ATTENTION! BECOME ALERT! YOUR SAFETY IS INVOLVED!
Safety is a primary concern in the design and manufacture of our products. Unfortunately, our eorts to provide safe equipment can
be erased by an operator’s single careless act. In addition, hazard control and accident prevention are dependent upon the awareness,
concern, judgment, and proper training of personnel involved in the operation, transport, maintenance and storage of equipment.
Make certain that the operator(s), prior to operating is instructed in safe and proper use and reviews and understands the manual(s)
pertaining to this machine.
Read this manual before you operate this machine. If you do not understand any part of this manual, or need more information, contact
the manufacturer or your authorized dealer.
SAFETY
Understand that your safety and the safety of other persons is measured by how you service and operate this machine. Know the
positions and functions of all controls before you try to operate them. Make sure to check all controls in a safe area before starting your
work.
The safety information given in this manual does not replace safety codes, federal, state or local laws. Make certain your machine has the
proper equipment as designated by local laws and regulations.
A frequent cause of personal injury or death is from persons falling o equipment and being run over. Do not permit persons to ride on
this machine.
Travel speeds should be such that complete control and machine stability is maintained at all times. Where possible, avoid operating
near ditches, embankments and holes. Reduce speed when turning, crossing slopes and rough, slick or muddy surfaces.
Collision of high speed road trac and slow moving machines can cause personal injury or death. On roads, use asher lights according
to local laws. Keep slow-moving-vehicle emblem visible. Pull over to let faster trac pass.
Make sure that the header is fastened securely to the transport before moving.
Make sure that everyone is clear of equipment before applying power or moving the machine. NEVER position yourself under or near
header when mounting on the header transport.

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. SAE Fasteners

TIGHTENING WHEEL NUTS: Standard 1/2” wheel studs and nuts should be tightened to torque 120 ft-lbs. During initial operation
of the header transport and then checked 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.

Safety Rules
Bolt Torque Chart
Make sure that the implement is fastened securely to the tractor by using the proper hich pin, clip and safety chains.
Before unhooking the implement from the towing unit, be sure to properly block the wheels to prevent the implement from moving.
Never overload the header transport. Overloading the header transport is dangerous and can cause extensive damage.
Do NOT exceed speeds in excess of 25 MPH. The header transport is designed for heavy loads at slow speeds. Also be sure slow moving
vehicle emblem is attached to rear of wagon.
IMPORTANT: Use caution when transporting. Be alert of the transport unit’s overall width when approaching obstacles, such as post signs
and poles, along the road. Check the transport width of the unit to ensure clearance before entering bridges.
COMPLY WITH ALL SAFETY WARNINGS AND CAUTIONS IN THIS MANUAL AND IN THE COMBINE OPERATOR’S MANUAL.

INITIAl OPeRATION / MAINTeNANce
BeceRTAIN ThAT All POweR IsshuT Off BefORe seRvIcINg The heAdeR TRANsPORT
Before the header transport is put into service:
• Has the Slow-Moving Vehicle Emblem 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 operators manual.
• Are all braces, bolts, nuts, lug bolts 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.
OPeRATINg INsTRucTIONs/ MAINTeNANce
• Adjust the brackets on the header transport to best t your make and model header. When mounting the header, NEVER position
yourself under or near the header.
• 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.
• 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 bearing lubricant such as Bearing Guard MK1
or equivalent.
• Insert the amount of grease needed into all of the grease zerks shown in the image above.
• Be sure to check the hub nuts often and keep them properly tightened.
• Check alignment of tires yearly. Adjust the push pull bar to realign the tires if needed.

1. Locate the tongue in the straight and horizontal position. Check this by measuring reference lines“A”and “B”. These
measurements are the same when the tongue is straight forward.
2. To adjust the toe-in of the tire on the front axle, measure the distance between the wheels at the centerline of the tires.
Dimension “C” should be 1/8”to 1/4” shorter than dimension “D”. If not, loosen the locknuts on both ends of both front tie
rods. Adjust both front tie rods evenly as needed. Re-tighten the locknuts and recheck the dimensions.
