Kodiak Aerators are available in Pull Type (with optional wheels) or three-point hitch design. Both feature a 12" diameter drum that can be filled for additional weight. Made with solid cold rolled steel axle attached to pillow block bearings for longer life and better operation. Utilizing a standard 15/16" x 7" core tine, the unique design allows slight movement during operation to allow easier penetration when encountering subsurface obstacles with easier release of plugs. This design reduces the possibility of clogged cores.
