The Millcreek Spin Groomer is a rotary harrow that can work wonders for hard, compacted baseball and softball infields. It spins as you pull it, and fills in the low spots with material from the high spots. Because it moves material sideways, a single pass can level the ruts along base paths and the low spots at the player positions.The Spin Groomer is easy to use – no PTO required. Just hook it up, drop it into position and go. You set the angle of attack and let the Spin Groomer’s bolt-on, hardened steel tines do the rest. The optional rake attachment helps smooth the surface following the aggressive spin groomer action. Millcreek Spin Groomers come in a range of sizes: 5, 6, and 7 foot diameter models.
