Most of activities in agriculture are performed with machines and equipment. In many farms, these objects do not meet basic safety standards. Therefore, it was conducted a survey on 180 farms, whose major purpose was to determine the most common category of accidents at harvest. Main categories include: inappropriate handling of machine and an assessment of the technical condition of appliances. Obtained results show that, most frequently occurring reasons of accidents related with machines are: missing protective covers, missing reflectors and lack of handrails. Among the most common accidents are the following: falls, hits by machine moving parts and hits by the vehicle in motion. It was found that farmers do not respect the principles of safety during handling of machine and do not participate in training courses and workshops of this subject. Therefore, farmers should perform all the activities with full responsibility and use machines in good condition.
