PERFORMANCE EVALUATION OF AN OBSTACLE AVOIDANCE MOWER ASSEMBLY IN TRUNK TYPE PEAR ORCHARD

To solve the problem of mechanized weeding in trunk type pear orchard, combined with the technology of stubble elimination and hydraulic obstacle avoidance, the authors designed an obstacle avoidance compound mower. This paper carried out a field performance evaluation test to verify its usefulness. Six indexes were tested to evaluate its working performance. The results were: inter-row crushing rate of 89.99%, intra-row miss cutting rate of 2.42%, stubble stability coefficient variation of 4.25%, working efficiency of 0.32 hm(2)/h, fuel consumption of 16.25 L/hm(2), profitable area of 0.75 hm(2). The study could provide a reference for orchard mechanized weeding.
