The goal of researches was to evaluate the efficiency and power requirements of mowers and weeding equipment in organic
orchard. It has been determined a hourly productivity of machines and expenditures on inter-row cultivation. During the
season 5-8 weeding and 7-9 mowing treatments were made. Working speed and efficiency of machines depended on the
weed infestation and the grow stage of turf, ex. the speed of the tractor with mower was from 4.4 to 7.8 kmh-1. Working efficiency
of weeding machines depended on the degree of weed infestation, and it amounted from 0.4 to 1.2 hah-1. Working efficiency
of mowers was 1.0 to 1.5 hah-1. Power consumption of flail mower was 8.5 kW for 1 m wide on mowing turf and exceeded
the power needed to operate the drum mower. The maximum power demanded for orchard rotoculivator was higher
than for the machine with tilting working unit.
