Operating Instructions
This section covers general operating procedures. Expe-
rience, machine familiarity, and the following information
will lead to efficient operation and good working habits.
Always operate farm machinery with safety in mind.
Pre-Start Checklist
Perform the following steps before transporting the
NTA607HD or NTA2007HD air drill to the field.
High Pressure Fluid Hazard:
Escaping fluid under pressure can have sufficient pressure to
penetrate the skin. Check all hydraulic lines and fittings before
applying pressure. Fluid escaping from a very small hole can
be almost invisible. Use paper or cardboard, not body parts,
and wear heavy gloves to check for suspected leaks. If an acci-
dent occurs, seek immediate medical assistance from a physi-
cian familiar with this type of injury.
❑ Review “Important Safety Information” on page 1.
❑ Lubricate as indicated at “Lubrication and Sched-
uled Maintenance” on page 132.
❑ Check all tires for proper inflation. See “Tire Infla-
tion Chart” on page 147.
❑ Check all bolts, pins, and fasteners. Torque as
shown in “Torque Values Chart” on page 148.
❑ Check air drill for worn or damaged parts. Repair or
replace parts before going to the field.
❑ Check hydraulic hoses, fittings, and cylinders for
leaks. Repair or replace before going to the field.
Master Switch (Option)
This switch is present only if the optional Variable Rate
Kit is installed. The switch is normally located near the
DICKEY-john
®
console terminal.
The master switch controls the optional linear actuator(s)
on the variable rate gearbox(es). When the master
switch is off, it also signals the seed monitor system that
you are not presently planting.
The master switch and the lift switch control the linear
motor that engages the contact drive, when operating in
GRAN SEED CONTROL or GRAN FERT CONTROL
modes. In GRAN SEED/FERT MONITOR mode, only the
lift switch controls contact drive engagement.
