Leveling Implement
During initial setup and periodically throughout the
season, check that the implement runs level. When
applying fertilizer, the top of the main frame should be
parallel to the ground, and level left to right.
Set Application Depth
Before checking or correcting side-to-side or
front-to-back level, set the application depth (which is
controlled by tool bar height).
The Nutri-Pro
®
Liquid Fertilizer is designed for
application at:
0 to 6 inches (0 to 15.3 cm)
For adjustment, see “Application Height Adjustment”
on page 53.
To check level, lower the implement into the ground in
representative conditions.
Front-to-Back Level (Spacers)
The rear lift-assist assembly must be set to match the
gauge wheels and 2-point hitch in front. Lift-assist
lowered height is controlled by (provided) spacers on the
lift cylinder rods.
To set:
1. Lower implement until lift assist wheels are just off
the ground.
2. Raise implement until wheels touch ground just
firmly enough to resist spinning.
Refer to Figure 12
(which depicts a lock channel installed on the cylinder rod)
3.
Insert a combination of spacers to fill the space on
the rod between the cylinder end and clevis.
4. Raise and lower implement. Pull forward and check
coulter depth and front-to-back level. Adjust spacers
as required to achieve desired application depth.
5. Store unused spacers on any nearby hydraulic hose.
Make sure the spacers cannot slide into positions
that interfere with machine functions.
