measurement of the values of forces in tractor arms is of great importance due to draft of agricultural equipment. these values can be used for testing and evaluation of the agricultural machinery, selection of suitable tractor, etc. the tools which are used for measurement of the forces are called dynamometer. the main objective of the present study was to design and evaluate a load cell for i...

Kaplan–Meier analyses can be used in many disciplines, e.g., agricultural engineering. Agricultural machinery and vehicles regarded as objects that ‘die’ because, like living creatures, they failed, although after repair until scrapped. This article presents an example of using the estimator to plot reliability function curves five different models Zetor farm tractors. The research shows median...
