The Model 61 Pulverizer, Yard Tool is an excellent tool for the landscaper to prepare a yard for seeding. The front and rear teeth are offset to break up the soil while the rear roller pulverizes the dirt clogs to make a smooth finish for seeding. It is ideal for landscaping, leveling and to work up horse arenas. It will break up the hard crust where horses have run and prepare the ground for better hoof treatment. The adjustable 1 inch square teeth are easily replaced. The heavy rigid box frame is open at the top so trash and weeds will fall through and not be transported to another job. The spiral spiked roller mounted with pillar block bearings has spring tension on the roller to evenly spread the dirt. Free Shipping within 1,000 miles!
