Comparative analysis of rotating rake teeth for agricultural use

It is presented an analysis case performed as assistance to a producer in search of optimization in the quality of his line of agricultural use. The study applicant needs to find a root cause of the difference in in-service behavior of the lateral rake teeth between those of their own manufacture and others available on the local market.

These are curved steel rods with a diameter of 8 mm x 1300 mm, which are integrated into multi-tooth wheels which must show a totally elastic behavior during their use. The study is carried out on 4 samples received from different manufacturers. Using chemical and metallographic analysis, microhardness measurement and tensile tests, the characteristics of the different samples have been compared.
