BOLT TORQUE
Important: Over tightening hardware can cause as much damage as under tightening.
Tightening hardware beyond the recommended range can reduce it shock load
capacity.
All hardware used on the 8500 Series Head Cart is Grade 5 unless otherwise specified.
If hardware must be replaced, be sure to replace it with hardware of equal size,
strength, and thread type.
The chart below is a guide for proper torque. Use it unless a specified torque
value is given elsewhere in the manual.
Torque is the force you apply to the wrench handle times the length of the handle.
Use a torque wrench wherever possible
The following table shows torque in ft-lbs for coarse thread hardware.

10
SET UP INSTRUCTIONS
Tires and Wheels
1. Using a safe lifting device and jack stands rated at a minimum of 2500 lbs, raise
the frame at least 16 ½” high
2. Install wheels and tires onto the axles and secure with provided lug nuts. Refer to
the table below for torque sequence and value.
•Start all lug nuts by hand to prevent cross threading
•Tighten nuts in the sequence shown below
•Lug nuts should be torqued before first road use and after each wheel
removal. Check and re-torque after the first 50 miles. A periodic check
during regular service is recommended.

SET UP INSTRUCTIONS
Test Lights
Make sure no wires are pinched or cut during installation.
Keep all wires concealed to prevent them from getting caught on obstructions.
Attach 8500 Head Cart and wiring harness to tow vehicle to test the lights.
Check the following:
•Tail lights
•Brake lights
•Left and right turn signals with and without brakes applied
Note: If any of the light tests fail, check wiring harness on tow vehicle for proper
wiring.

OPERATION
Hitching
1. Position towing vehicle in front of header transport. Lift tongue latch handle and
extended inner tongue extension enough to attach to vehicle drawbar using a ¾”
minimum diameter hitch pin and lock in place. Back-up towing vehicle to re-latch
tongue.
2. Cross transport chains and connect to towing vehicle.
Note: Before hitching the header transport to any vehicle drawbar, be sure the pin
hole is located close enough to the rear of the vehicle drawbar to allow the
header transport tongue clevis to swing 90 degrees right or left of the centerline
without interference.
Note: When hitching, be sure not to pinch wire harness. Position the wire harness
away from all pinch points and any areas that may wear the harness.
CAUTION: BE SURE TRANSPORT TONGUE IS LATCHED
BEFORE TRANSPORTING, OTHERWISE JARRING COULD
OCCUR WHEN STOPPING UNIT, CAUSING A SUDDEN SHIFT OF
LOAD.
CAUTION: ALWAYS USE TRANSPORT CHAINS WHEN
TRANSPORTING IMPLEMENTS. FAILURE TO USE TRANSPORT
CHAIN COULD CAUSE PERSONAL INJURY OR DAMAGE IF
IMPLEMENT BECOMES DISENGAGED.

13
OPERATION
Tie-Down Brackets
•The tie down brackets consist of two heavy duty strap assemblies which secure
current design headers to the transport. For proper installation follow steps as
shown.
1. Loosen strap by pulling up ratchet handle and lock in open position
CAUTION: BE SURE RATCHES, WEBBINGS, AND HOOKS ARE IN PROPER
WORKING CONDITION SO THAT DAMAGE DOES NOT OCCUR DUE TO LOSS OF
HEADER FROM TRANSPORT
Note: Before tightening, be sure header is resting against backstops on lower rest
brackets.
Note: Be sure tie down bracket assemblies are secured to transport directly below the
section on the header that the tie down hook is being attached to. DO NOT ATTACH
BRACKET AND PULL STRAP AT AN ANGLE TO THE BRACKET TO SECURE. Doing
so could result in unnecessary stress and wear to tie down webbing.
2. Slide tie down bracket across lower rest tube and secure in appropriate location
under header by inserting carriage bolt, flat washer and knob. Tighten into
position by turning knob clockwise.
Note: It is recommended that the tie downs be secured to a main bar or sufficient
bar/tube on the combine head that is rigid enough to support total weight of
header. Failure to do so could result in damage to the combine header.
CAUTION: BE SURE ALL SHARP EDGES ARE REMOVED SO THAT WEBBING
DOES NOT BECOME CUT OR FRAYED.

14
MAINTENANCE
Bearings
•Every 12,000 miles or once a year, repack wheel bearings with grease
oInspect bearings for signs of wear such as discoloration of rollers,
spalling, pits, or metal flakes. Rollers and race should look shiny and new
if in good condition. If any of these signs are found, replace bearings
immediately.
Brakes
•Every 12,000 miles or once a year, inspect brake shoes for wear. Be sure to
replace brake shoes before friction material wears away entirely. Failure to do so
can cause damage to the brake drum.
