Lubrication and Maintenance
Maintain approximately 25 mm ± 13 mm of blade-to-blade
contact 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 25 mm ± 13 mm of
contact.
NOTE: Proper blade clearance is critical. Blades should have
25 mm ± 13 mm 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: Replace blades If proper blade-to-blade contact cannot be maintained after relocating machine
bushings or if blade diameter wears below 37 cm.
15" SEED OPENER DISC BLADE/BEARING ASSEMBLY
Approximately
25 mm
± 13 mm
blade-to-
blade contact.
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 22 N at outer edge of
blade.
