Overpitch Drive Tumbler
Allows 50% of Usable Track Shoe Lifespan
The Excel Overpitch Tumbler installs as a direct replacement for the conventional drive tumbler. A properly timed replacement extends the life of the track shoes and reduces additional damage on replacement tumblers. Operations get more uptime and extended life from their track shoes. The resulting performance simulates “like-new” pitch conditions.
