Maintenance Tips
-
Clean After Each Use: Remove soil, grass clippings, and debris from the tines and reel to keep cores clean and prevent buildup.
-
Inspect Before Operation: Check for loose, broken, or bent tines and fasteners; tighten bolts and replace damaged parts promptly.
-
Grease Bearings Regularly: Lubricate the pillow block bearings and wheel hubs with lithium NLGI #2 grease every season or after washing — this reduces wear and prolongs service life.
-
Check Tine Torque: Ensure tine reel nuts are tightened to specification to maintain aeration consistency. Inspect torque periodically.
-
Weight for Soil Penetration: Use water jugs or ballast positioned over the tines to increase penetration depth in firm soil.
-
Store Dry: Keep the aerator in a covered, dry space to avoid corrosion on hardware and tines when not in use.
-
Avoid Sharp Turns: With tines engaged, avoid tight or high‑speed turns to prevent turf damage or tine bending.
-
Periodic Part Replacement: Replace tines when they dull or bend — worn tines reduce aeration effectiveness.
