Spartan toothbars can be added to your existing bucket as a means to allow you to fracture tight or compacted soil more easily. Simply drill a hole on each side of your bucket and bolt on the toothbar. The shanks on the tooth bar hook over your existing cutting edge, where all the pressure is applied. The bolts simply hold the tooth bar on the bucket. Our mini skid steer tooth bar teeth are all replaceable crimp on style. Your bucket edge cannot exceed 1/2" thickness and if ordering for all non-Spartan brand buckets you must include your exact inside bucket width dimension.
