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.
LUBRICATION: USE #2 MULTI-PURPOSE POLYUREA 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 polyurea 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.
