This paper focuses on introducing the up to date mechanized production technology of direct-seeded canning tomato, by determining the machine operational hours needed for the production technology and for the transportation task, like input material-, and end product transport.The investigations prove that the number of machine operation hours of field tomato production are high. It helps that the self-propelled tomato harvester completely utilizes its annual operating hour by harvesting 100 hectares of land, which means that its utilization and specific cost is favourable.The results of the research show that 69 % of the total machine operational hours of the logistical tasks are related to end product transport from which the transport to the processing company takes 53 %. It is followed by harvest (10.5 %) and the proportion of the working hour demand of the other material handling operations of the technology almost reaches 5 % or 1 % in some cases.Due to the long distance transportation of the end product 74.4 % of the total machine operation hours of tomato production are related to harvesting and the connected logistical tasks. It is easily recognisable that the time of crop transport depend on the distance between the place of harvest and the processing company. This could be more time-consuming than the plant production, so the post-harvest logistics could be very important and significant.By the very careful handling of the product the harvester does not cause much damage to the tomatoes. Much more damage is caused during transport, so it is very important to take the crop to the processing company in the shortest possible time.
