17 Preparation and Setup
Hitching Tractor to Drill
You may be severely injured or killed by being crushed
between the tractor and drill. Do not stand or place
any part of your body between drill and moving trac-
tor. Stop tractor engine and set park brake before in-
stalling the hitch pin.
1. Use the drill jack to raise or lower the tongue
as needed. Hitch the drill to the tractor using a
hitch pin of adequate strength (at least one
inch in diameter).
2. Install a retaining clip on the hitch pin to pre-
vent it from working up. Securely attach drill
safety chain to tractor drawbar.
Escaping fluid under pressure can have sufficient pres-
sure to penetrate the skin causing serious injury. Avoid
the hazard by relieving pressure before disconnecting
hydraulic lines. Use a piece of paper or cardboard,
NOT BODY PARTS, to check for leaks. Wear protective
gloves and safety glasses or goggles when working
with hydraulic systems. If an accident occurs, see a
doctor immediately. Any fluid injected into the skin
must be surgically removed within a few hours or gan-
grene will result.
3. Connect hydraulic hoses to tractor remotes.
Refer to “Hydraulic Hose Hookup,” page 16.
4. Plug the drill light cable to the tractor. If outfit-
ted with an optional population monitor, con-
nect monitor lead to monitor harness.
5. Plug electric clutch cable to the switch control
box cable.
Note: Switch control box should be mounted
in your tractor cab in a location with easy ac-
cess. Route wiring harness with enough slack
to allow for tractor movement, especially artic-
ulating tractors.
6. Crank the jack until tongue weight is resting
on the tractor drawbar. Unpin the tongue jack
from the hitching stob. Pin the jack to the stob
on top of the tongue.
