Fergtrac safety frame for Ferguson tea-20 tractors: Strength characteristics

Abstract

Strength tests were made using testing apparatus similar to that used by the National Swedish Testing Institute for Agricultural Machinery and the National Institute of Agricultural Engineering, Silsoe, England to establish whether or not the safety frame is of adequate strength to prevent excessive deformation in the event of an overturning accident. The deflections of this frame during impact and crushing tests were within satisfactory limits. The frame did not unduly affect accessibility, visibility or maintenance, but noise caused by the vibration of the removable front brace was annoying.
