1) Hook tractor to Nitro-Gro and adjust hitch so that frame
on applicator is level or tilting back slightly.
2) Hook up hydraulic lines.
Set #1 - Green Hoses - Raise & Lower/ Wing Kick/ Down-pressure
Set#2 - Red Hoses - Wing Fold
Set#3 - Black Hoses - Hydraulic Pump
IMPORTANT - For the black hoses hook the return hose to a
low pressure return port at the tractor.
3) Raise the unit to relieve pressure on
transport latches and wing rests. Remove transport
latch pins and place in storage holes next to the
lock holes.
4) Unfold the unit.
5) 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. It is
a good idea to be moving forward when lowering the toolbar.
6) Adjust the wing Gauge wheels so that the coulters on the wings are at the same depth and
the toolbar is level when lowered.
7) Using the desired rate of application (GPA) and speed of application (MPH), use the supplied
orifice sizing chart on pages 50-51of this manual to determine which orifices will provide
optimal application pressure. Install the orifices in the check valve unit above each row unit
that is mounted on the coulter shaft.
NOTE – The unit will be either be set up to skip a row, "One Down", or re-apply the
outside row,"One Up".
-If the unit is set up as "One Down" (11 or 15 coulters) then the outside coulters on
each end of the unit will need to be 1.5x rate of the other coulters.
-If the unit is set up as "One Up" (13 or 17 coutlers) then the outside coulters on
each end of the unit will need to be 0.5x rate of the other coulters.
8) Put some water in the tank and check for leaks.
IMPORTANT - Before proceeding to the next step make sure that the valve is open to the pump. NEVER
run the pump dry.
9) With the valve to the pump open perform the initial setup of the pump as outlined in the pump owners manual.
After the pump is set up recheck the applicator for leaks.
10) In-field adjustment of hydraulic down-pressure: Adjust so that the coulters are staying at desired depth with the
least amount of hydraulic pressure necessary.
IMPORTANT - DO NOT exceed 1,350 PSI.
11) Adjust tractor hydraulic flow on the Raise and Lower/Wing Kick/Down-pressure circuit as low as possible while
maintaining a reasonable toolbar raise and lower speed. This will help prevent creating excess heat in the hydraulic
system as this circuit provides continuous toolbar down-pressure.
12) Fold the wings up for transport.
IMPORTANT - Be sure to have the toolbar fully raised before folding the wings up! Failure to do so will
result in damage to the unit.
