Linear disc-aerator

The Imants RotoKnife is a versatile and effective linear disc-aerator. The RotoKnife is designed to relieve surface compaction, improve aeration, reduce thatch buildup and remove surface water. By eliminating a PTO drive, the RotoKnife is fast across the surface and a versatile root zone management tool. The disc rotor shaft can be set in five different positions offering flexibility in working depth and linear spacing, allowing deep slitting to a depth of 6”, or shallow slitting at 2” spacing. The RotoKnife can even be used as a surface smoothing roller.

• Minimal surface disruption
• Increases soil’s ability to move water
• Increases aeration
• Excellent for managing thatch and black layer
