Leveling Applicator
During initial setup and periodically throughout the
season, check that the applicator runs level. When
applying, 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
®
Anhydrous is designed for application at
4 to 6 in. (10 to 15 cm)
For adjustment, see “ Application Depth ” on page 96.
To check level, lower the applicator into the ground in
representative conditions.
3-Point Leveling
Refer to Figure 18
Leveling is controlled entirely by the tractor hitch.
2-Point 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 applicator until lift assist wheels are just off
the ground.
2. Raise applicator until wheels touch ground just firmly
enough to resist spinning.
Refer to Figure 19
3. Insert a combination of spacers to fill the space on
the rod between the cylinder end and clevis.
4. Raise and lower applicator. Pull forward. Check
knife/tine depth and front-to-back level. Adjust
spacers as required to achieve application depth.
