Product Details

Designed as a smaller form factor RotoKnife, the Imants Mini RotoKnife is a linear disc-aerator designed to relieve surface compaction, improve aeration, reduce thatch buildup and remove surface water. The Mini RotoKnife is fast across surfaces and a versatile root zone management tool. Rotor shafts can be set in three different positions, offering flexibility in working depth and linear spacing. One 8″ disc shaft allows for variable-depth slitting from 3/4″ to 2 1/2″ deep at 4″ spacing. Two 8″ disc shafts can be used in tandem at a depth of 1 1/2″ with 2″ spacing. The Mini RotoKnife is compatible with most compact tractors and can also be used as a surface smoothing roller.
