Field Operation Checklists
Perform all steps in “ Pre-Start Checklist ” on page 45
and “ Field Set-Up Checklists ” on page 78. The
applicator is presumed to be unfolded and raised.
Spill hazard/Tank damage risk:
Periodically check the tension of the straps for the fertilizer
tank. Strap tension will change as outside air temperature
changes. Adjust tension as necessary to prevent personal
injury or damage to the fertilizer tank.
 These are merged anhydrous (NH

) and
conventional liquid (NH

a. Monitor flow divider pressure during end-of-pass
operations and turns. Adjust operations as needed if true
zero pressure is desired.
b. These steps are for a full stop prior to a turn. If the lift is
conducted while in motion, the exact order of hitch and
lift-assist raising is not critical. The objective is to avoid
any reverse motion of tines.
