The forged link needs to be replaced on certain D6M Tractors. The hard forged link attached the bottom of the blade to the C-frame structure may break. This type of failure may occur when the machine is working in a muddy environment and with mud packing around the forged link. In those cases an improved lower dozer link may be installed.AFFECTED PRODUCT
