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 cotter pin
and adjust the slotted nut to remove wobble, recommended torque of 150 in. 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 LITHIUM GREASE
To ensure longevity and reliability of the 2960-020 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 cotter pin, slotted nut, washer and bolt 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 150 in. 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.
