KING KUTTER'S PROFESSIONAL LAWN AERATOR is designed to aerate lawns and athletic fields, producing holes in which, water, fertilizer, and oxygen, can be more effectively moved into the soil, and in contact with the roots. Water, nutrients, and oxygen are all important factors for root growth and overall turf health and the result is a healthier, greener, thicker grass. The upper frame is intended to hold weight for added down pressure in especially tough conditions. Dual parking stands ensures that you will never have to pick up your aerator, and the CAT. 1 quick hitch compatable hitch make it safer and easier to hook up.
