Abstract: In order to improve the harvest quality, an oblique cutting and feeding device was designed and tests were conducted in this paper. The experiments of the cutting and feeding device included properties experiment and compatibility experiment of harvesting sugarcane in different growth state. Results showed that rupture rate was 20%, whole stalk rate 60%, feeding rate 100% and loss rate 12.6% under the condition that forward speed was 0.43m/s, knife plate speed 450rpm and knife plate dip angle 8°. Compatibility experiment result showed that sugarcane adaptability was better when relative position of sugarcane and the dual base cutter was minus 100 mm, lodging attitude angle 40°,slip angle 30°, and relative position of sugarcane and the dual base cutter was equal to minus 100 mm, lodging attitude angle 60°and slip angle 0.
