I'm looking for a five-wheel tricycle equipped with a hydraulic dumping bucket. The engine should be at least 300 cc and feature a water cooling system to ensure efficient performance. I'd also like to know more about the design and features that enhance its utility, especially for heavy-duty tasks. Please provide details on the available models that meet these specifications, including pricing, lead times, and any customization options. Additionally, I'd appreciate info on warranty and support services you offer post-sale. Looking forward to your response with the relevant details to help me make a well-informed decision.
