The combination scarifier/drag is designed to break up hard, crusted playing surfaces. The heavy-duty welded steel angle iron construction will hold concrete blocks when needed. Dual action groomer has large 2 1/2" scarifying teeth on one side and works as a leveling drag on the other side. Measures 6' wide and 16 1/2" deep for added stability. Includes a tow chain and a 1" solid steel drag bar for smoothing and leveling after scarifying. Concrete blocks not included.
