The research was performed on a registered agricultural farm in the village of Selevac, municipality of Smederevska Palanka. The family farm Šiljić has a total of 5,4 ha of used agricultural land. In production season 2019/2020 wheat was sown on 2 ha and 1 ha of maize, sunflower and triticale each. On the area of 0,4 ha is a backyard and garden. The farm owns a tractor IMT-558, a plough, a disc harrow, a harrow, a sprayer and a trailer, purchased in 1979. The old machinery is in use. The registered family farm Šiljić is insufficiently equipped with mechanization. With a two-axle tractor with a power of 42.65 kW and 5 attached machines cultivates 5.4 ha, so the energy equipment is 8.5 kW/ha. The tractor is mostly engaged in the production of corn 10,0 h/ha, sunflower 9,5 h/ha, triticale 8,33 h/ha and the least is wheat 7,41 h/ha of effective work. On the farm Šiljić, on the area of 5 ha, out of a total of 42,66 hours of work, the tractor was mostly used in the basic tillage 17,0 h or 3,1 h/ha. The tractor is also engaged in pre-sowing soil preparation with a disc harrow 9 h (1,8 h/ha) and a harrow 7 hours (1,4 h/ha), in a transport 5,33 h (1,07 h/ha), in the application of pesticides with a sprayer 4,33 h (0,87 h/ha). In addition to the total effective work in the implementation of certain agro-technical measures in the production of field crops, the tractor was hired at 7,30 hours to leave and return from the plot (auxiliary working hours). Fuel consumption in basic tillage was 18 l/ha, in presowing preparation with a disc harrow 10 l/ha, harrow 5 l/ha and 5 l/ha in the application of pesticides and transport of products.
