• Set the down pressure just high enough to keep the gauge wheels in contact with the ground. Excessive pressure
can cause premature wear on wing pivots and gauge wheels.
•
IMPORTANT - DO NOT EXCEED 1,350 psi.
• Set the center section of coulters first. Spacers are included with the toolbar cylinders. Add or remove spacers until the
center section is positioned at the appropriate depth. Lower the unit until the lift cylinders bottom out on the stroke control
spacers. Add or remove stroke control spacers until the center toolbar section reaches desired application depth. For best
results, move forward while lowering the toolbar.
• After the center toolbar is set with the cylinder spacers, adjust the wing gauge wheel setting until the wings are level
with the base section and the entire toolbar is flat and even. Once the toolbar is set and leveled, further adjustment is
typically not necessary.

Follow these maintenance guidelines during the intial operation of your NitroGro applicator.
First 30 minutes of operation:
1. Ensure all coulters and nozzles are clean and working properly. Clean and adjust accordingly.
2. Check all hydraulic and chemical lines. Be sure none of them are kinked, pinched or leaking. Adjust lines accordingly.
3. Re-torque all of the wheel bolts.
4. Check all other fasteners and hardware. Adjust accordingly.
5. Lubricate all grease fittings.
6. Ensure that outside wings are not creeping up. If needed, adjust the counterbalance valves. Refer to “Counterbalance Valve” on page
13 for instructions.
After 4 hours of operation:
1. Ensure all coulters and nozzles are clean and working properly. Clean and adjust accordingly.
2. Check all hydraulic and chemical lines. Be sure none of them are kinked, pinched or leaking. Adjust lines accordingly.
3. Re-torque all of the wheel bolts.
4. Check all other fasteners and hardware. Adjust accordingly.
After 10 hours of operation:
1. Ensure all coulters and nozzles are clean and working properly. Clean and adjust accordingly.
2. Check all hydraulic and chemical lines. Be sure none of them are kinked, pinched or leaking. Adjust lines accordingly.
3. Re-torque all of the wheel bolts.
4. Check all other fasteners and hardware, especially the u-bolts that secure the coulters to the toolbar. Tighten if needed.
Upon completing the initial break-in period, begin the standard maintenance schedule as described in “Service” on page 33.
Initial Operation
•
Comply with ALL state and local laws governing highway safety and regulations when moving machinery on public roads.
•
Be sure an SMV (Slow Moving Vehicle) emblem is in place and clearly visible on the rear of the applicator. Position the SMV emblem
with one point of the triangle upward and as near to the rear and centered or as near to the left of center of the unit as practicable.
Secure the SMV emblem two to ten feet above the ground measured from the lower edge of the emblem. Before transporting,
ensure that all lights, reflectors, and the SMV emblem are clean and visible. Ensure the amber, red, and orange reflective tape on the
implement is in place and clearly visible. Before transporting, ensure all lights, reflectors, and the SMV emblem are clean and visible.
•
When transporting applicator, do not exceed 10 MPH in the field or over rough terrain. For highway transportation, do not exceed
20 MPH. Reduce transport speed when necessary to maintain full control. Never transport the applicator with contents in the tank.
•
Tongue weight when NitroGro is folded and empty for road transport is 600-1,000 lbs depending on the configuration. Negative
tongue weight (even intermittent) may cause instability when transporting. Add ballast to tractor as required. Never tow this
implement with a motor vehicle. Tow only with a properly ballasted tractor.
•
Be aware of overhead wires when transporting.
•
Ensure the safety chain has a rating greater than the empty weight of the machine.
•
Ensure wings are seated in the transport saddles before transporting.
