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.14 pages© NZAEIstrength teststractor safetyReportANZSRC::400204 Automotive safety engineeringANZSRC::409901 Agricultural engineering
