inexperience operators.
• Make no modifications to this equipment unless specifically requested or recommended by DuraTech
Industries.
• Tighten or replace any loose or cracked bolts, chains, hoses or connections.
• The towing vehicle must be of equal or greater weight than the grain drill for adequate braking capacity.

9
77/107 DRILLS OPERATING INSTRUCTIONS
DURING OPERATION
• Exercise extreme caution with operating the drill on steep slopes or grades.
• Be sure all spectators are clear of the area where the drill is in operation or raised and lowered.
• Be sure the tractor operator is the only person riding the tractor. Allow no one to ride the drill at any time.
• Remember, loose clothing, necklaces and similar items are more easily caught in moving parts. Avoid
the use of these items if possible and keep long hair confined.
• Never work under the drill when the drill is lifted up unless the safety stop bar is in position.
• Watch out for and avoid any object that might interfere with the proper operation of the machine.
DURING SERVICE & MAINTENANCE
CAUTION: Before performing any maintenance or adjustments make sure machine is NOT
running.
• Before working on or near drill for any reason including servicing, lubricating, cleaning, inspecting or
refilling, or if working under drill or detaching from tractor, install safety stop bar (next to hydraulic
cylinder).
• When replacing any part on your drill, be sure to use only DuraTech Industries authorized parts.
• Relieve all pressure in the hydraulic system before disconnecting the lines or performing other work on
the system. Make sure all connections are tight and the hoses and lines are in good condition before
applying pressure to the system.
CAUTION: Hydraulic fluid escaping under pressure can be invisible and have enough force to
penetrate the skin. When searching for a suspected leak, use a piece of wood or cardboard rather than
your hands. If injured, seek medical attention immediately to prevent serious infection or reaction.
• Be careful when using a hoist or other lifting device. Use only devices that have adequate lifting capacity
and be sure the chain or cable is securely attached.

10 77/107 DRILLS OPERATING INSTRUCTIONS
WHEN TRANSPORTING ON PUBLIC ROADS
• Use good judgment and drive carefully, especially over rough or uneven roads.
• Be sure tractor brakes are properly adjusted and foot pedals locked together.
• Check your state laws regarding the use of lights, slow moving vehicle sign, safety chain and other
possible requirements.
• Do not tow drills at speeds over 20 mph. It is recommended that drills be empty of seed or fertilizer
when transporting.

11
77/107 DRILLS OPERATING INSTRUCTIONS
IMPORTANT WINCH SAFETY INFORMATION
• The winch is built for multipurpose hauling and lifting operations. It is not to be used as a hoist for
lifting, supporting or transporting people, or for loads over areas where people could be present.
• Respect the winch. High forces are created when using a winch, creating potential safety hazards. It
should be operated and maintained in accordance with instructions. Never allow children or anyone who
is not familiar with the operation of the winch to use it. A winch accident could result in personal injury.
• Check winch for proper operation on each use. Do not use if damaged. Seek immediate repairs.
• Never exceed rated capacity. Excess load may cause premature failure and could result in serious
personal injury.
• Never apply load on winch with cable fully extended. Keep at least three full turns of cable on the reel.
• Secure load properly. When winching operation is complete, do not depend on winch to support load.
• Operate with hand power only. This winch should not be operated with a motor of any kind. If the
winch cannot be cranked easily with one hand, it is probably overloaded.
FAILURE TO COMPLY WITH ANY OF THE ABOVE SAFETY INSTRUCTIONS OR
THOSE THAT FOLLOW WITHIN THIS MANUAL MAY RESULT IN SEVERE INJURY
OR DEATH.
THIS DRILL IS NOT TO BE USED FOR ANY PURPOSE OTHER THAN THAT FOR
WHICH IT IS INTENDED AS EXPLAINED IN THE OPERATOR’S MANUAL,
ADVERTISING MATERIALS AND OTHER PERTINENT WRITTEN MATERIAL.

Section 2: Dealer Preparation
2.1 Gauge Wheel Attachment
The heavy duty gauge wheels mount on the tool bar in front of the drill. The gauge wheels are adjustable to maintain a
uniform planting depth when on side hills.
INSTALLATION
Step 1: Place the gauge wheel mount assembly in front of the second run assembly from either tool bar end.
See the accompanying illustration.
Step 2: Mount the gauge wheel mount assembly to the tool bar by using two gauge wheel mount straps and
four 5/8” x 6-1/2” hex bolts, lock washer and nuts provided. See accompanying illustration.
Step 3: Repeat Step 1 and Step 2 for the gauge wheel on the other side of the tool bar.
Step 4: Lift the tool bar using the drill’s hydraulics and insert both gauge wheels into the bottom of the
gauge wheel mount assemblies. See the accompanying illustration.
Step 5: If conditions prevent Step 4 from being done, the gauge wheels can be inserted into the front of the
gauge wheel mount assemblies. To do this, remove all four bolt sleeves (two per gauge wheel
mount assembly) by unbolting the four 3/4” x 6” hex bolts, lock washers and nuts and push the
gauge wheels into the mount assemblies. Bolt the bolt sleeves on to the gauge wheel mount
assemblies again.
Step 6: Adjust the gauge wheels to the desired position by inserting the adjustment handle through the
proper gauge wheel adjustment with the hair pin. This adjustment determines the gauge wheel
