Performance Test of QY42R Robotic Lawnmower

In order to solve problems of weed cutting in the narrow area of agricultural and rural areas including old orchard, according to standard GB/T 10938—2008 "rotary mowers" and GB/T 14176—2012 "forestry machinery, gasoline powered portable brush cutters and grass trimmers", performance of QY42R robotic lawnmower was tested． Results showed that QY42R robotic lawnmower has good performance , in which utilization coefficient of cutting range was 99.8%, net cutting rate could reach 99.1%, and there was basically no missing cutting． Its pure operation efficiency was 0.152 hm²/h, which was about 4.2 times of that of manual mowing． Meanwhile, operating cost was more than 48% lower than that of manual mowing．
