Studies on Trial SK Universal Blade for Bush Cutter

Abstract

As described in the previous report, the piano-wire blade, consist of universal joint mechanism, was designed so that it could be increased the durability for striking against the obstacle, such as the stone, but it has been bended sometimes under mowing for stony field condition. Improvements were undertaken to eliminate the above disadvantages of piano-wire blade, and SK universal blade was produced by way of experiment. Results of durability tests of SK blade indicated to be satisfactory. The bush cutter mounted SK blade was operated under varying condition to evaluate it performance and to determine whether it met the established design objectives.
