DOZER BLADES The Tuffstuddds Wear Protection System is a proven method of protecting dozer blades. Tuffstudds applied to blades and push arms reduces operating and maintenance costs. By extending the life of the dozer blades with Tuffstudds wear protection, there is a saving through less downtime, labour and material costs. Maximum life of push arms is attained when protected with Tuffstudds. Tuffstudds are quickly and efficiently applied to severe wear areas on the blade. Multiple applications on original wear plate. Applied pattern becomes embedded with mineral debris causing a dead bed effect, which further enhances wear resistance.
