Yetter 2982-001 V.T.A. - Manual (Page 8)

OPERATION
- The V.T.A.™ should be operated 6-10 mph.
- Level the toolbar frame so that the coulter blades are the same depth front to back
and side to side.
- Operate the coulter blades at 3” +/-1” in the soil.
- If needed, add ballast or weight to maintain coulter blade depth.
1. Set/mount coulter blades to run perpendicular to the soil. Operation depth and
blade wear can be affected if the shank 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.
