Removing small cores of soil from your lawn reduces soil compaction, relieves thatch accumulation, and promotes root growth for healthier grass!

Core aeration can help make your lawn healthier and reduce its maintenance requirements through these means:

  • Improved air exchange between the soil and atmosphere.
  • Enhanced soil water uptake.
  • Improved fertilizer uptake and use.
  • Reduced water runoff and puddling.
  • Stronger turfgrass roots.
  • Reduced soil compaction.
  • Enhanced heat and drought stress tolerance.
  • Improved resiliency and cushioning.
  • Enhanced thatch breakdown.

With Easy Steer Technology, the Lawnaire IV Aerator, B & S Engine, 554914E maneuvers around highly landscaped areas—quickly and efficiently. Designed to rotate independently while driving, innovative tine assemblies allow you to steer without removing the tines from the ground.

  • Hollow steel coring tines: Removes solid cores. Hardened alloy steel coring tines stay in the ground when you turn
  • Easy Steer Technology: Easily maneuver along paths and contours. Cores stick in the ground without tearing up the turf.
  • Sized to your needs: Slim 19-inch aeration width

Watch for the Bobcat branded AE19.

Ryan equipment is transitioning to a Bobcat branded version and will soon be available for purchase on and at Bobcat dealerships. Parts will continue to be available on and on
