SAFETY

A brief description of signal words that may be used in this manual:

CAUTION: Used as a general reminder of good safety practices or to direct attention to unsafe practices.

WARNING: Denotes a specific potential hazard.

DANGER: Denotes the most serious specific potential hazard.

SAFETY PRECAUTIONS

You can make your farm a safer place to live and work if you observe the safety precautions given. Study these precautions carefully and insist that those working with you and for you follow them.

Finally, remember this: an accident is usually caused by someone’s carelessness, neglect or oversight.

WARNING

Never clean, lubricate or adjust a machine that is in motion. Always lower or block the implement before performing service.

If the machine must be serviced in the raised position, jack or block it up to prevent it from accidentally falling and injuring someone.

Do not allow riders on the tractor or implement.

Use speeds and caution dictated by the terrain being traversed. Do not operate on any slope steep enough to cause tipping or loss of control.

Be sure all personnel are clear of the immediate area before operating.

Read and understand the operator’s manual and require all other persons who will operate the equipment to do the same.

Be familiar with all tractor and implement controls and be prepared to stop engine and implements quickly in an emergency.

CAUTION

Consult your implement and tractor operator’s manual for correct and safe operating practices.

Beware of towed implement width and allow safe clearance.

FAILURE TO HEED MAY RESULT IN PERSONAL INJURY OR DEATH.

BOLT TORQUE

Mounting bolts and hardware

Before operating the 2910-130-HD Coulter for the first time, check to be sure that all hardware is tight. Check all hardware again after approximately 50 hours of operation and at the beginning of each planting season.

All hardware used on the 2910-130-HD Coulter is Grade 5 unless otherwise noted. Grade 5 cap screws are marked with three radial lines on the head. If hardware must be replaced, be sure to replace it with hardware of equal size, strength and thread type. Refer to the torque values chart when tightening hardware.

Important: Over tightening hardware can cause as much damage as when under tightening. Tightening hardware beyond the recommended range can reduce its shock load capacity.

The chart below is a guide for proper torque. Use it unless a specified torque is called out elsewhere in the manual. Torque is the force you apply to the wrench handle or the cheater bar, times the length of the handle or bar. Use a torque wrench whenever possible.

The following table shows torque in ft. lbs. for coarse thread hardware.

Lubricate all bearings and moving parts as assembled and make certain that they work freely.

WARNING: Never work around the toolbar/implement while in a raised position without using safety lockups.

CAUTION: The coulter disc attachments are very heavy. Pay extra attention to lifting techniques while handling and or maneuvering the opener during assembly. Failure to do so may lead to

personal injury.

INSTALLATION

1. Assembly 3/8 x 2-1/2” roll pin into hole closest to end of 1-1/2” diameter shank, leaving approximately equal amount protruding out each side. Note: offset shanks require that you perform step 2 first then step 1.

2. Insert lock collar into pivot casting and slide shank up through casting and lock collar. Slide shank up till roll pin contacts casting surface. Install and tighten 5/8 x 1” setscrew in lock collar to 110 ft. lb. torque maximum.

3. Mount blade to hub using four 1/2 x 1-1/2” carriage bolts, lock washers and nuts.

4. Assemble clamp components loosely to the tool bar as shown in parts view of appropriate clamp. Tighten four 1/2” nuts to secure the clamps.

5. Slide shank up through clamps and tighten 5/8 x 1” setscrews.

6. Install 5/16 x 2-1/2” cotter pins in all vertical 1-1/2” diameter shanks. This cotter pin prevents loss of coulter should the clamp setscrews work loose. Cotter pin can be installed between clamp castings or on top, above top casting depending on the shank.

7. Set lock collar to allow swivel in one or both directions as required. Tighten set screw to 110 ft. lb. torque maximum.

8. Set spring tension by adjusting 3/4” lock nut until 1/8” of threads are exposed above the nut. Tighten 3/4” locknut if greater spring pre-load is required.

OPERATION

1. Set/mount coulter blades to run perpendicular to the soil. Operation depth and blade

wear can be affected if the coulter is mounted crooked or if the toolbar is not level side to side.

2. After a few hours of use, check all bolts for tightness and proper torque.

3. After a day of use (10-12 hours) check coulter hubs for loose bearings. There should be

no endplay in the hub bearings allowing the blade to wobble. If necessary, remove hubcap and cotter pin and adjust the slotted nut to remove wobble, recommended torque of 15 ft. lbs. and re-insert cotter pin. If the wobble or looseness cannot be corrected, the bearings, cups and seals will need to be replaced.

DO NOT USE WORN OR DAMAGED PARTS.

MAINTENANCE

LUBRICATION: USE #2 MULTI-PURPOSE BEARING GREASE

To ensure longevity and reliability of the U.N.T. Coulter, the recommended lubrication schedule should be followed using multi-purpose grease at hourly intervals as indicated.

BEARING ADJUSTMENT:

1. Raise the toolbar until the blade is clear of the ground. Place a safety stand under the toolbar.

Remove the hubcap, cotter pin, slotted nut and washer from the hub assembly. Remove the blade from the hub assembly.

2. Remove bearing cones and seals from hub.

3. Wash the old grease from the hub, bearing cups, spindle spacers, seals and bearing cones.

Inspect the condition of the bearing cups, cones and seals. Replace if necessary.

4. Apply #2 multi-purpose lithium grease on each bearing. Make sure the space around each roller is

filled. Lubricate the bearing cups.

5. Position the bearing in the cup and install the seal. Lubricate the seal lips and proceed with re-

assembly of the removed parts including the blade. Blade bolt torque is 90 to 96 ft. lbs.

6. Tighten the slotted nut to 15 ft. lbs. or until a definite drag is felt when the blade is turned by hand.

Tighten the nut one slot position to line up the cotter pin hole with a slot. Secure the nut with a new cotter pin, replace hubcap.
