WARNING!
Towing the drill at high speeds or with a vehicle that is not
heavy enough can lead to loss of vehicle control. Loss of vehicle
control can lead to serious road accidents, injury and death.
The reduce the hazard:
• Do not exceed 20 mph.
• Do not tow a drill that, when fully loaded, weighs more
than 1.5 times the weight of the towing vehicle.
Minimum Towing Vehicle Weight
16,000 pounds
Hydraulics
Your tractor must have two remote outlets.
Safety Lights
Your tractor must be wired for the standard 7-pin electrical
connector. If your tractor is not equipped with this connec-
tor, consult your dealer for installation.
Hitching Tractor to Drill
1. Use the drill jack to raise or lower the tongue as need-
ed. Hitch the drill to the tractor using a hitch pin of ad-
equate strength (at least one inch in diameter).
2. Install a retaining clip on the hitch pin to prevent it from
working up. Securely attach drill safety chain to tractor
drawbar.
3. Connect hydraulic hoses to tractor remotes. One pair
is for the four field-lift cylinders. The other pair is for
raise-to-fold, transport-lock, fold and marker cylinders.
!
WARNING!
Escaping fluid under pressure can have sufficient pressure 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, im-
mediate medical attention from a physician familiar with this
type of injury.
4. Plug the control-console cable to the drill harness.
Plug the drill light cable to the tractor.
5. Crank the jack until tongue weight is resting on the
tractor drawbar. Unpin the tongue jack from the hitch-
ing stob. Pin the jack to the stob on top of the tongue
as shown in Figure 2-1.
