Abstract: Aiming at the problems of soft soil in Guizhou mountains,  small land area,  large slope,  and the inability of the existing pepper harvester to travel on the mountain,  a crawler selfpropelled pepper harvester suitable for hilly and mountainous areas was designed. The chassis of the harvester is used as the object,  and the passability and stability of the harvester during mountain driving are studied. RecurDyn is used to simulate the process of chassis driving on horizontal slopes,  vertical slopes,  over vertical walls,  and crossing trenches. The simulation results show that when the harvester is running on a clay road with a full load,  the maximum slope angle of crossslope driving is 22°,  the maximum slope angle of vertical slope uphill is 30°,  the maximum slope angle of downhill is 21°,  the maximum height over a vertical wall is 510 mm,  and the maximum width across the trench is 1 020 mm. The field test results of the harvester show that the relative error between the maximum value of the harvester uphill,  vertical wall crossing,  and ditch crossing and the simulation results is 10%,  1.96%,  and 3.92%. The test results are similar to the simulation results. The test verifies that the harvester has good stability and passability during the driving and can meet the current requirements of Guizhou mountain pepper harvesting.
