The maximum grade which the Tinger Dog is capable of passing varies with types of surface (ice, snow, rocky surfaces, etc.). Generally, the Tinger Dog can pass areas, where a person could climb on foot without using one’s hands for additional balance. However, this is a heavy duty operation for Tinger Dog, resulting to increased wear of the belt and the continuously variable transmission, so do not overuse riding across hills. A long ride uphill also has an impact on the engine but the operation in a sloped position is an abnormal operation mode with potential oil starvation, which can also result in premature engine wear. Please refer to the engine owner manual for the operating incline angle limitations.
