Only a guard that is formed and machined to the exact dimesions and hardened to the specified hardness assures maximal performance on todays high capacity harvesting machinery. The selection of the best forging steel and the appropiate hardness in point, ledger and body of the forged guard result in a guard that does not bend, break or wear prematurely. The total heat treatment process converts the steel structure to the desired combination of hardness and toughness.
Precision machining of the knife slot and other wear surfaces of the forged guard are absolutely necessary to have best section to guard ledger contact. |
