38
Toe in setting is out of specification
Loose or corroded wires, contacts
Loss of electrical ground connection

Header is positioned on the trailer
too flat
Ratchet straps not holding the
header
Ratchet strap hook becomes loose,
Worn steering components
Toe in setting is out of specification
Tire rim bent
Improper tire for application
Improper set up on header wagon.
Loading area uneven
Have a qualified person adjust the toe-in. The factory
setting for both axles should be .3175 - .635 cm (1/8"
– 1/4") tow-in
Check the trailer side plug for loose or corroded wires,
loose wires in the light casing, replace or repair as
required
Check the tow side receptacle for loose or corroded
wires or damaged receptacle, replace or repair as
required
Check connection to ground on the trailer side and the
tow vehicle side. Disconnect and clean or replace
terminal.
Brakes: have a qualified technician inspect the
braking system.
Solution
Increase the angle of the top rail mounts so that the
header puts more pressure on its heal points that rest
in the universal shoes. As well increase the angle of
the universal shoe
Tighten up the ratchet straps, check straps, hooks
and strap mechanism for wear / damage, replace if
required
Reposition the ratchet straps closer to the ends of the
wagon may provide better leverage
Attach point seems deformed: move the ratchet strap
to a different attach point that is more ridged. If
required, find a ridged metal point and mount a 3/4"
grade 5 eye bolt to use as an attach point.
Ratchet is not positioned directly below attach point,
the ratchet will slide. Position the ratchet directly
below the attach point
Check for wear or excessive play in
- wheel bearings
- steering spindles
- ball joints
replace any components that are worn out
Have a qualified person adjust the toe-in. The factory
setting for both axles should be .3175 - .635 cm (1/8"
– 1/4") tow-in
Check tire rims for wobble while rotating, replace if
bent.
Check that your tire type matches your application.
Example: Ag tires used consistently on highway will
wear prematurely. Replace tires with correct type.
Adjust the height of the top rail so that the header
beam will make contact with the wagon before the
heal of the header.
Find an area that is flat as possible to help with
alignment while loading/unloading.
