Lubrication and Maintenance
NOTE: No till planting or planting in hard ground
conditions, especially when planter is not equipped
with no till coulters, and/or excessive blade-to-blade
contact increases seed tube guard wear and requires
more frequent inspection and/or replacement.
Remove seed tube and two hex socket head cap screws
that attach seed tube guard. Hold replacement seed tube
guard centered between seed opener disc blades. Install
hex socket head cap screws. DO NOT TIGHTEN. Using
a clamp or vise-grip, squeeze opener blades together in
front of seed tube guard. Tighten seed tube guard retaining
screws. Remove clamps. Distance between seed tube
guard and opener blades should be equal on both sides.
Reinstall seed tube.
SEED TUBE GUARD/INNER SCRAPER
Seed tube guard protects seed tube and acts as inner
scraper for seed opener disc blades.
Remove seed tube and check for wear. Excessive wear
on seed tube indicates a worn seed tube guard. Replace
seed tube guard if it measures " (16 mm) or less at lower
end. A new seed tube guard measures approximately
" (22.2 mm).

to hold bearing and bearing housing in place. Install rivets in other three holes. Remove ¼" cap screws and install
rivets in those three holes.

excessively worn seed tube guard may
allow blades to wear into row unit shank,
also requiring replacement of shank.
