Aeration Hole Quality

• Coring Depth: Poor quality can result if the depth is set too deep. Decrease the tine depth by 6 mm (1/4 in.) to 12.7 mm (1/2 in.) and check for improved hole quality.
• Tine Type: Closed tubular tines will provide better quality holes than open-side tines. Use open-side tines in applications to overcome plugging in high sand-content soils or wet conditions.
• Turf Guard: The turf guard needs to be firmly on the surface during operation or lifting may occur. This lifting is especially prevalent in turf with poor root conditions. Excessive turf guard pressure can cause marking in soft turf.
• Engine Speed: The throttle solenoid modifies engine speed as the aerating head is raised or lowered to maintain hole quality in certain turf conditions. The solenoid may be adjusted or shut off with toggle switch if desired for certain applications.
• Damaged Aerating Linkage: If the hole quality is bad in one aeration linkage path only, then that associated linkage may have a damaged or missing part. First, inspect the linkage for any missing or loose hardware. Sometimes damaged linkage will make unusual noise. Check for bent tines. Straighten or replace tines if needed. Replace linkage if needed.
• Hard Soil: The machine will raise up off the turf in hard soils conditions and the hole quality may be less than desirable. Water the areas to be aerated before to soften up hard soils.
