Safe "T" safety frame for Fordson major tractors

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 frame is of adequate strength to prevent excessive deformation in the event of an overturning accident. The deflections of the frame during impact and crushing tests were within satisfactory limits. The frame did not unduly affect accessibility, visibility, or maintenance, and no change in the noise level to which the driver is subjected was noticed when the frame was fitted.
