The MT-48x48 design creates "Dirt on Dirt" wear points to extend the life of the foot tips. Designed to be pulled individually or in tandem, it features zero grease zerks, a proprietary replaceable tip design, and no hard surface welding required to maintain its life. It utilizes sizeable oil-bathed bearing packs for drum rotation. The sheepsfoot roller can also be ordered in a double or triple ballast drum configuration for maximum compaction.
