Abstract: China is a big fruit producer in the world.With implementation of orchard grass-covering technology in recent years，rapid development of orchard lawn mower is imminent.Key components of orchard mower，such as cutting device，walking system，copying device and related achievements，and key technologies such as navigation，obstacle avoidance and automatic identification，were analyzed and expounded.At the same time，application status of lawnmowers at home and abroad were introduced and analyzed，and typical models，characteristics and existing problems of lawnmowers at home and abroad were summarized with combination of traction，ride，hand mowers and field management mowers.Combined with two kinds of orchard planting patterns of short anvil type dense planting with Joe anvil optimum plant type，problems in development of lawn mowers in China were summarized，such as poor combination of agricultural machinery and agronomy，low level of R & D and manufacturing，improper matching between operating speed of machines and tools and working speed of cutters，and lack of application of high and new technology，it was proposed that in application of lawn mower，should pay attention to combination with agronomy，improve level of design，R & D and production manufacturing，pay attention to solving matching between working speed of lawn mower and working speed of cutter，strengthen application of high and new technology，realize automation，intelligent and information application of lawn mower as soon as possible，and promote mechanized weeding process of orchard.
