Checking Planter Height
The planter is designed to operate with all sections of the
main tool bar nominally 26 inch (66 cm) above the
planting surface. The height of the center section is not
routinely adjustable. Set planting depth with row unit
adjustments.
When lowering the planter for the first time on the
planting ground:
1. Completely lower the main tool bar. If necessary, first
lift off transport locks, remove and stow locks.
2. Set hitch to planting height.
3. Pull forward a few feet or just over a meter.
Height Mis-adjustment Risk:
Fully lower planter to field position (with openers into ground)
and set hitch height before making side-to-side adjustments.
4. Check tool bar height across planter. See page 106
for further detail and adjustment.
