ROPS design for pre-ROPS tractors.
J Agromed 1997 Aug; 4(3/4):309-311
A study was being conducted to identify and categorize tractors built before the development of rollover protective structures (ROPS) in order to determine axle mount designs appropriate for ROPS design and testing, and to design, construct and test a ROPS for three major axle housing categories identified. This included conducting static and field upset ROPS testing in accordance with ASAE S519. The ROPS design, construction, and static and field tests of the first major axle housing category were completed for the initial axle category, which included the Ford 8N/800 series tractors. The second major axle housing category was selected and included the axle design for the John Deere A, B, G, 50, 60, 70, 520, 620, 720, 530, 630, and 730 tractors. A John Deere tractor was modified for field upset testing. The third major axle housing category was selected based on the available tractor databases and discussions. The axle category covered the Farmall H, M, Super H, Super M, 300, 400, 350, 450, and 460. While ROPS for some of the tractors have been available, a more economical two post design was needed for commercialization. The results from the project indicate ROPS can be successfully mounted to preROPS tractors to provide protection to the operator in the event of a tractor overturn. Many preROPS tractor axle housings are similar, so that one ROPS design and mounting configuration can be used for several tractor models.
