Abstract:  Aiming at the current situation and domestic market requirements of grass raking technology, a new grass collecting machine was put forward with the backing of the 13th fiveyear plan of the National Key Research and Development Program of China. The overall design and working principle of the 9JSC-7.0 grass picking and collecting machine were described briefly. Frame, pickup, conveyor, profiling mechanism, and hydraulic system were introduced. The experiment results in the field showed that pickup width was 7.2 m, the working speed was from 5 to 15 km/h, the loss rate of pickup strips was 3.7%, and the machine was stable and reliable at work. The technical indexes could meet the demands of project tasks and design. It has important guiding significance to research on the highefficient and highquality grass harvesting.
