Safe "T" safety frame for Ford 2000 and 3000 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 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 was subjected was noticed when the frame was fitted.
