In ordor to improve the abilities of slope-climbing and overturn-resisting of light weight and small size watering cart for dual purpose of both sprinkling irrigation and hose irrigation, the vertical and horizontal stabilities of the cart were analysed. The factors that affect stabilities of the device in vertically and horizontal slope were theoretically depicted, the relationship between stability and various factors were discussed, and gradient angle for no-gliding and no- overturning was calculated. Results show that higher viscidity coefficient of ground possess more favorable advantage for the stabilities of the cart. The stabilities of watering cart can be improved effectively by ways such as increasing the spacing of wheels and that between the mid axes of wheels and the touchdown point of flow pipe, reducing the hight of barycenter. The climbing ability can be improved by ways such as increasing the traction and reducing the weight of watering cart.
