Leveling Planter
The planter must be level for the row units to function cor-
rectly. Before leveling the planter check tire pressures as
specified on Tire Inflation Chart, “Appendix,” page 39.
1. Check that planter is level from side to side. If not, ad-
just lower links of tractor three point to level planter.
2. After setting row units to the proper planting depth,
park tractor and planter on level ground in the field.
Lower planter. If planter is level from front to back, the
bottom of the frame tube will be parallel to the ground
(1). See Figure 1-4. If planter is not level, adjust upper
link on tractor three point to level planter.
3. Check that row-unit arms are parallel to the ground. If
row-unit arms are not parallel, adjust gauge-wheel
modules.
To find the amount of adjustment needed, measure
the vertical distance between the front and rear pivot
on the row-unit arms (2). See Figure 1-4. Adjust both
gauge-wheel modules this amount.
To adjust the gauge-wheel modules, see Figure 1-3.
