The new tooth is more robust and improves destumping efficiencies.
The mounting block, neck, and strike point have been combined into one large cutting tool. Rayco explains that unlike other tooth designs, the Super Tooth has extra mass in the neck to eliminate bending, twisting, and breaking that can cause machine shut down and high maintenance costs. It also increases cutter wheel thrust, balance, and inertia for improved performance. The tooth’s low profile design gives extra clearance for the mounting block to pass by the stump without obstructing the strike point or dragging against the stump. Because the strike point is unobstructed, the carbide tip is in full contact with the material to be removed. It cuts cleanly through the wood, providing full utilisation of the machine’s power for cutting and discharging chips. The Super Tooth’s mounting block has more surface area in contact with the cutter wheel. This eliminates gouged cutter wheels, a common problem with tooth/pocket designs that clamp teeth between the cutter wheel and mounting block. Rayco lists the following features:
- A one piece design constructed of high alloy tool steel
- Extra mass in the tooth neck to eliminate bending, twisting, and breaking
- A low profile mounting block with more clearance from strike point to mounting block to eliminate drag
- A carbide tipped strike point cuts cleanly through the stump to maximize horsepower
- More surface area in contact with the cutter wheel to provide support and eliminate gouged cutter wheels
- Designed to fit industry standard cutter wheels with 3.9 cm (1.53 in) bolt centres
- Easy to change and install using 5/8-18UNF cap screws
- The simple bolt on design does not require gauging or indexing
