Preparing the NitroGro Applicator:
IMPORTANT - Before putting the applicator into operation, check the machine for damaged or worn parts and replace as
necessary.
Only use a tractor with sufficient power and weight to operate the applicator. For 24 rows, use a minimum of 275 hp tractor and for 36
rows use a minimum of 410 hp tractor. Be sure the applicator is properly attached to the tractor, the pin is properly secured, and the
safety chain is properly installed. Inspect all safety decals for visibility and remove any debris.
Lights and SMV:
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.
Hardware:
Ensure all hardware is properly fastened according “Bolt Torque Chart” on page 8. Recheck all hardware for tightness after the unit
has been operated for several hours. Check that all pins and retaining rings are in good condition. Replace any pins or retaining rings
that are worn, damaged or missing.
Hydraulic Hoses:
Ensure hydraulic hoses are not kinked, twisted, or rubbing against sharp edges. Secure hoses to the applicator with nylon tie straps.
Check hoses and fittings for hydraulic leaks. Tighten or replace hoses or fittings as necessary.
Lubrication:
Lubricate the NitroGro applicator according to the Lubrication Schedule outlined in “Service” on page 33.
Tires and Wheels:
Check the tire pressure in the transport and gauge wheel tires and make sure the tire pressure is equal for each tire. Refer to “Operation”
on page 18 for tire pressure reccomendations. Tighten standard 3/4” wheel studs and nuts on transport tires to torque 400 ft-lbs and
tighten 1/2”-20 studs and nuts on gauge wheels to torque 80 ft-lbs. Check the wheel lug nuts before initial operation and after the unit
has been operated for several hours to ensure the lug nuts remain tight.
Filling the tank:
Warning: Ensure the applicator is pinned to the tractor before filling tank. The applicator must be pinned to a tractor when any
fluid is present in the tank.
Make sure the area is clear of bystanders when filling the tank. Always wear protective clothing, gloves, and masks when handling
fertilizer/chemicals. Follow the fertilizer/chemical manufacturer’s instructions when filling the tank. Keep the tank lid on at all times to
keep out debris.
Fertilizer Pump:
Raise the toolbar with wings unfolded and turn on the fertilizer pump. Check if liquid is coming out of each knife/injector. Clean or
replace knives/injectors if necessary.
Unfolding the Wings:
It is recommended to unfold the side wings in the field. Keep all bystanders away while unfolding the wings. See “Folding & Unfolding”
on page 16.
