3.5 Equipment Matching
To insure the safe and reliable operation of the applicator, it
is necessary to use a tractor with appropriate specifications.
As a guideline, insure that these requirements are met:
Tractor Horsepower:
1.
Refer to table below minimum recommended
horsepower for your machine. Although recommended
tractor horsepower is not required to pull machine, it
does provide required strength in drawbar as hitch is
very heavy. This will also insure that the unit has the
required stability and control in hilly terrain and during
transport.

Front End Weights:
2.
By following recommendations for tractor power, tractor
will have sufficient weight to provide stability during field
operation or when transporting. It is also recommended
that each tractor be equipped with a full compliment of
suitcase weights on front of tractor. This will provide the
required weight on front for turning and extra traction if
equipped with front wheel assist.
Hydraulic System:
3.
Tractor hydraulic system must be capable of 8 gpm (24
lpm) at 2000 psi (13,800 kPa) to operate lift cylinders
and drive motor. Either closed center or open-centered
systems can be used. However an open centered
hydraulic system is limited to 8 gpm maximum.
Note: Contact factory for an optional flow control for use
with high flow open center system.
Three remote outlets are required to operate the
applicator.
Tool bar lift cylinders and wing kick.
1.
Inner wing extend/fold cylinders and outer wing extend/
2.
fold cylinders
Chemical / fertilizer pump drive motor.
3.
Note: Always place hydraulic control lever in detent to
provide a constant flow of oil to pump drive motor.
3.6 Controls
It is recommended that all operators review this section of
manual and metering pump manual to familiarize themselves
with location and function of all machine controls and
settings before starting.
Metering Pump:
1.
An Operator’s Manual is supplied with machine. Review
manual carefully to determine required hydraulic setting
on pump for your application.
Liquid System Pressure Gauge:
2.
This gauge monitors pressure in liquid circuit providing
flow to injector orifices. It is normally used to determine
pressure in chemical/fertilizer circuit when setting
system for a specific application rate. Monitor gauge
during operation. Stop and check system if pressure
changes suddenly.
