Lubrication and Maintenance

15" SEED OPENER DISC bLADE/
bEARING ASSEMbLY

Approximately 1" ± ½" of blade-to-blade contact

should be maintained to properly open and form seed

trench. As blade diameter decreases due to wear, it is

necessary to relocate machine bushings from inside to

outside to maintain 1" ± ½" of contact.

NOTE: Proper blade clearance is critical. blades

should have 1" ± ½" contact in this area. When

blades are turned by hand in opposite directions

against each other, there should be only light

resistance to turning. Re-adjust blade scraper if

necessary to center it between the blades.

NOTE: If proper blade-to-blade contact cannot be

maintained after relocating machine bushings or if

blade diameter wears below 14½", blades should

be replaced.

NOTICE

Excessive blade contact may result in premature

disc opener bearing/hub failures and excessive

wear on seed tube guard/inner scraper. When

properly adjusted, if one blade is held in fixed

position, opposite blade should rotate with less
than 5 pounds force at outer edge of blade.

1. Remove gauge wheel.

2. Remove scraper.

3. Remove bearing dust cap.

4. Remove cap screw, washer and disc blade/bearing

blade are used to maintain approximate 1" ± ½" of

blade-to-blade contact.

shank threads require replacement of row unit
