The Replacement Shank is designed to replace broken shanks on the Box Blade Tractor Attachment and the Land Leveler and Grader. Sold individually, the scarifier tooth is forged from solid steel and crafted with four adjustable holes for changing the height of the shank. The durable tooth is tapered for easy digging and is great for ripping up to 5-inches of high-packed dirt. It is good practice to check the shanks each season to see if there are cracks, wear and tear, or a loss and to fasten bolts that may have become loose.
