To prolong the life of your NitroGro applicator, hook the applicator to a tractor, unfold it, and perform the following before
placing the implement in storage:
1. Pressure wash the NitroGro applicator to remove dirt and debris that may cause rusting.
2. Repaint any areas where the paint has been chipped, scratched or worn away.
3. Coat all earth-moving surfaces with a suitable rust preventative.
4. Inspect for damaged or worn parts and replace before next use. Examine all hydraulic hoses and fittings for wear and
replace or tighten as necessary.
5. Grease coulter hubs.
6. Replace all worn, torn, or faded decals and reflectors.
7. Flush all fertilizer from the system and winterize the applicator if kept in cold storage.
IMPORTANT - To winterize your NitroGro drain the tank and all fertilizer hoses. Once the system is drained add
approximately 50 gallons of RV antifreeze. Run the antifreeze thru the strainer, valves, check valves, and orifices.
8. Cover flow monitors from the sunlight. If flow monitors are exposed to the sun for a long period of time they will turn
cloudy and become difficult to see through.
9. Store the implement inside and sheltered from inclement weather on an area that is dry, level, and clear of debris.
10. Fold up applicator and unhook from tractor.
11. Lubricate the plunger shaft. Ensure the toolbar raise switch valve is functioning properly. Switch should return to the
closed position when not triggered. The pictures below show the valve in the closed and open positions. If the switch
does not return to the closed position, gently tap the plunger (circled in the pictures below) down with a hammer. Add
lubrication to the plunger shaft and work the valve open and closed until the plunger returns to the closed position
freely under its own spring pressure.
