TYMCO skid plates are manufactured through a unique and patented technology using a foundry process whereby molten steel is poured around preformed Kennametal carbide inserts. The result is a part with the excellent abrasion resistance of carbide and the ductility (resistance to breakage) and weldability of steel. This process produces skids with very uniform, evenly spaced carbide inserts positioned closely together. The patented molten steel poured around these inserts is air hardened to a Brinell hardness in the 500-600 range. Competitors using the brazed or button type of skids must use relatively soft, low carbon steel (225-230 Brinell hardness) to insure adequate brazing or provide machineability for the button type. This soft steel and inconsistent spacing results in: 
- Loss of the pick-up head’s air tight seal due to wear gaps.
- Significant reduction in sweeping performance.
- The loss of the inserts themselves.
The design of the TYMCO skid plate as noted above lends itself to very evenly distributed wear along the full length of the skid.
TYMCO DUO SKIDS are also reversible. Should uneven wear be experienced due to misadjustment of the skid plates or floatation springs, the skid plates can simply be reversed and adjusted making it possible to realize 100% wear life on each. Many users have experienced in excess of three years of wear on one set and are still going! Our confidence in the TYMCO DUO SKIDS is evidenced by our two year warranty.
