Methods for Increasing the Material Resistance of the Mulching Tool Body Against its Deformation in Operation

Open access

Abstract

Instruments working in the cultivation of forest areas, for example under the guidance of high stress, are exposed to factors of heterogeneous environment which are soil, wood, various types of rocks, sometimes waste - metal, plastics or glass as well. The mulching tool body, the forging, deforms and worsens rapidly after loss of the WC toe-caps. Currently used tools have a non-heat-treated body material with a ferritic-pearlitic structure that has low abrasion resistance. One of the possibilities is to heat the tool body. Another possibility is to apply suitable welds to exposed areas. By correctly selecting the thermal mode of the tool material or by applying the welded material to the exposed body part of the tool, we can ensure that the tool's operating time is increased.
