Lubrication and Maintenance
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 mm.
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.
