General Information
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. Also make certain that the operator(s) reviews and understands the operator’s manual of the tow vehicle
prior to hooking up or operating the SpeedTender.
Read this manual before you operate this machine. If you do not understand any part of this manual, or need more information, contact
the J&M or your authorized dealer.

Safety Rules
1. Understand that your safety and the safety of other persons are measured by how you service and operate this machine. Know the
positions and functions of all controls before you try to operate them. Check all controls in a safe area before starting your work.
2. The safety information given in this manual does not replace safety codes, federal, state, or local laws. Ensure your machine has the
proper equipment as designated by local laws and regulations.
3. A frequent cause of personal injury or death is from persons falling o equipment and being run over. Do not permit persons to ride

4. Secure safety chain to towing vehicle before transporting. Do not transport without safety chains being attached to tow vehicle.
IMPORTANT: USE ONLY 2-5/16” BALL HITCH TO TRANSPORT UNIT.
5. Use good judgment when transporting on a highway. Always maintain complete control. Regulate speed to road conditions.
WARNING: BE SURE ALL LIGHTS ARE WORKING PROPERLY BEFORE HIGHWAY TRAVEL.
6. Travel speeds should be such that complete control and machine stability is maintained at all times.
7. Where possible, avoid operating near ditches, embankments and holes. Reduce speed when turning, crossing slopes and rough, slick
or muddy surfaces.
8. Make sure that the header is fastened securely to the transport before moving.
9. Make sure that everyone is clear of equipment before applying power or moving the machine. NEVER position yourself under or near

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 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.
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.
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.
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.
• Grease the ball using the zerk on the front gooseneck assembly every 8 hours or as needed.
• Check the wheel nuts often and keep them properly tightened.
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
tractor 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.
