3P1006NT Table of Contents Index Preparation and Setup
Semi-Mounted Hitching
If a hitch extension is required, mount it on the tractor
before hitching the drill.
1. Raise or lower tractor 3-point arms, or hitch
extension, as needed and pin lower arms to drill.
Upper arm is unused.
2. Set your tractor 3-point draft control to float
position.
Equipment Damage Risk
Do not raise 3-point until after hydraulic and
electrical connections have been made.
Hydraulic Hose Hookup
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. Use paper or
cardboard, not body parts, and wear heavy
gloves to check for suspected leaks. If
injured, seek immediate medical attention
from a physician familiar with this type of
injury.
Connect hydraulic system to tractor before lifting the
drill.
The hydraulic system of the drill has one dual-acting
lift-assist cylinder.The cylinder raises the rear of the
drill during lift (tractor 3-point lift arms raise the front).
There is a counterbalance valve in the system to
prevent sudden drops due to leaks or hose rupture.
1. Determine which tractor remote to use for lift
assist, and set the lever for that circuit to float (to
relieve any pressure).
2. Connect the lift hose to the extend port of the
tractor remote. Connect the return hose to the
retract port.
If lift is uneven, when the hydraulic system is first
charged, and if air is allowed in the system, bleed the
system. See “
Bleed Hydraulics ” starting on
page 30.
Great Plains hydraulic hoses are color coded to help
you hookup hoses to your tractor outlets. Hoses that
go to the same remote valve are marked with the
same color.
Electrical Connection
1. Make sure tractor is shut down with accessory
power off before making connections.
2. Connect lighting connector and any options or
after-market electronics to tractor outlets.
3. Tie up excess cable, allowing enough slack for
the drill to tilt back.
Make Electrical Connections
Make connections prior to machine
movement.

Leveling the Drill
Crushing Hazard
To avoid serious injury, do not raise drill
higher than necessary to adjust wheels.
Level the drill in field conditions. If done on hard
ground or pavement, coulters and openers may
prevent correct drill level.
1. Make sure the caster locks are not engaged. See
“
Caster Locks ” on page 17.
2. Extend the lift-assist cylinders. See “ Drill Raise
and Lower ” on page 16.
3. Initially adjust the tractor 3-point lift arms so the
opener tube runs at the recommended initial
height of 62.9 cm (A) above the ground when the
drill is lowered in the field.
