Changing Spacing
This is a two person operation. If the applicator frame is
not exactly level, the caster arms may be difficult to
control with one hand.
1. Hitch the applicator to a suitable tractor (page 36).
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 lift circuit to Neutral and
shut off the tractor.
5. Remove the hairpin cotter at a caster pin . Have
one person control the caster position. Remove the
pin.
6. Reposition the caster as desired for the new spacing.
Insert the pin. Secure with cotter. Repeat for other
caster.

7. Attach a hoist or lift to a caster to support its weight.
8. Loosen the four nuts at the clamp bracket.
9. Slide the bracket and caster toward implement
center by 15 inches. Re-tighten nuts to

swath of the implement change. Configure the
ground drive pump or controller console for 13 rows
and the wider swath. “Fertilizer Rates” on page 88.
12. On triple-coulter applicators, take steps to prevent
the rear boom pump from operating. Remove the
contact wheel or a chain from a ground drive. Leave
the hydraulics disconnected for a hydraulic pump.
