Abstract: In view of the characteristics of large terrain drop and fragmentation of plots in Guizhou hilly tea gardens, small tea garden field management machine cannot ensure ditching consistency, and the large‑scale tea garden management machine is large in size, poor traffic conditions and low in production efficiency. Therefore, a wheeled field management machine suitable for hilly tea gardens in Guizhou was developed. The overall design of the whole structure of the tea garden management machine was carried out. The minimum actual power of the equipment was calculated theoretically. Before the tea garden field experiment, the armrest bracket device and imitation depth limiting device were adjusted to make it suitable for different height operators and ditching operations in different regions tea garden; after the tea garden field experiment, the ditching depth was detected, and the machine was continuously optimized according to the field experiment results until it was finalized. The field experiment results show that the trenching depth of the machine was 174-236 mm, the average trench depth was 202 mm, and the trenching depth stability coefficient is 92.4%. The ditching performance parameters of the machine which has good flexibility and versatility meet the agronomic requirements of tea garden field management.
