Caster Angle Adjustment
Applies to NP2540 only. NP2540BL has fixed angle
lift-assist caster arms.
Your operations may require that the lift-assist tires be
in-row or out-of-row. In-row spacing varies with basic
applicator row spacing. Post-emergence (side-dress), for
example, typically requires out-of-row placement. The
forward caster parallel arm weldments may be pivoted
and pinned for wheel spacing.
Changing Spacing
This is a two person operation. If the applicator frame is
not precisely level, the caster arms may be difficult to
control with one hand.
1. Hitch the applicator to a suitable tractor (page 34).
2. Raise the applicator. Move to a level, and firm or
hard surface.
3. While raised, remove any lift lock channel or spacers
on the lift-assist cylinder.
4. Lower the applicator until the caster tires are just out
of ground contact. Set the fold/lift circuit to Neutral
and shut off the tractor.
5. Remove the hairpin cotter at a caster pin. Have one
person control caster position. Remove the pin.
6. Reposition caster as desired. Insert pin. Secure with
cotter. Repeat for other caster.
Loss of Control and Machine Damage Risks:
Never operate with one or both pins removed, or with pins
installed but not in a caster weldment tube. Always install the
caster pin from the top, in case cotter is lost. If the caster arms
are free to pivot at both ends, they can strike other applicator
components, and directional control is substantially reduced.
This could contribute to machine upset, a road accident,
serious injury or death.

The available wheel spacings are controlled by pins in
each caster assembly, through top&bottom holes and a
mid plate hole. Row spacings and tire center-line to
