Objective Considering the characteristics of diverse vegetable types, varies agronomic practices, and irregular ridge specifications in the hilly areas of southern China, a vegetable field transfer equipment to the planting mode and agronomy in the southern hilly areas, a vegetable field transport platform with adjustable track gauge was designed to enhance the adaptability of the field transport equipment to planting patterns and agronomy in the hilly regions of southern China. Methods Based on the characteristics of ridge planting and terrain in vegetable fields, the overall design of the platform was carried out, and its working principle was elucidated. The dimensions of the platform were 2165×1205×1154 mm. The design of key components such as the gearbox, traveling device, transmission system, adjustable track gauge device, and chassis were conducted. SolidWorks software was used for three-dimensional modeling, setting material properties for parts, and calculating the center of gravity position. Platform stability was analyzed based on the center of gravity position, and a virtual simulation prototype was built using RecurDyn for longitudinal uphill, downhill and transverse slope driving simulation analysis. Results The dynamic simulation results showed that under full load conditions, the maximum climbing angle for uphill driving was 39°, and the maximum descending angle for downhill driving was 27°. For transverse driving, the maximum slope angle under two extreme track gauges were 29°and 39°, respectively. A prototype was manufactured and stability tests were conducted. The test results showed that the maximum longitudinal uphill and downhill slope angle were 30°and 25°, respectively, and the maximum slope angles under the different gauges were 22°and 33°,respectively. Performance and field test were carried out,and the results showed that the platform met the design requirements and achieved satisfactory performance in terms of driving speed, turning radius, slip rate, and deviation rate under full load conditions. Conclusion The vegetable field transport platform exhibited strong adaptability to vegetable transport operations in the hilly and mountainous areas of southern China. By adjusting the track gauge, it can adapt to different vegetable agronomic practices,providing reference for tracked transportation equipment.
