The safety of using machines and technical devices, including agricultural tractors, is the most important element during their operation. The state of safety is influenced by many factors such as: safe construction, proper use, operating conditions and the human factor. Man is the most important and at the same time the weakest element of the safety system and the cause of many dangerous events. The largest number of accidents in agriculture occur due to human causes and they occur most often in developing countries, where many machines with a long service life are used. That is why the renewal of the machinery park and the safe construction of cabins even in the simplest agricultural tractors are so important. This article focuses on the strength analysis of the agricultural tractor cabin as an element that directly affects the safety of the tractor operator during various works performed in agriculture. Using finite element analysis, two cases of the impact on the agricultural tractor cabin were analysed. The first case illustrates the occurrence of a top impact on the cabin of a beam, a roll of straw, while the second case is the often-occurring classic overturning of the tractor, the so-called ROPS case of rollover. The cabin structure was modelled from square cross-section profiles made of S235JR steel, as the most commonly used for this type of structure. Numerical analysis was performed in ABAQUS for the ROPS test and static and modal durability analysis in MSC Nastran. Positive results of the analysis were obtained.
