Design of Hydraulic Motor Operated Bush-Cutter

Abstract

In the India, farmers encounter issues with trimming boundary bushes and unwanted vegetation that obstruct roadsides, railway tracks, and electricity poles. This overgrowth is particularly noticeable after rainfall. When it encroaches onto roadsides, it creates obstacles for machinery, bullocks, and pedestrians. Typically, manual labor is employed for bush trimming, involving hand-operated secateurs, various types of axes, bill hooks, pruning saws, and other manual tools. This manual approach is not only risky but also physically demanding, expensive, and time-consuming. The transmission of mechanical power over extended distances is inefficient and not only cumbersome but also has several disadvantages when compared to hydraulic power. Thus, the hydraulic motor operated bush-cutter was designed. If the developed machine cannot withstand the substantial forces encountered during bush cutting/pruning operations, it can become ineffective due to plastic deformation or component breakage. Therefore, it is imperative to meticulously design the developed machine to enhance its operational lifespan and reduce farming costs. A Solid Works software was used to create 3D models and simulation of the machine.
