A 190cc Engine + Hydrostatic Transmission... Bad Idea?

For this mini dumper build, I used a hydrostatic transmission from an old broken lawn tractor. This transmission provides smooth speed control in both forward and reverse, as well as automatic braking. The power comes from an old 190cc lawn mower engine. The frame was built in a simple but strong and durable way. My goal was to keep the design as simple as possible and avoid complicated mechanisms. That is why I used a single rear steering wheel instead of a more complex steering system with two wheels, links, and a pivoting axle. The finished machine turned out much better than I expected. The dumping mechanism is easy to use, the cargo bed is surprisingly spacious, and the hydrostatic drive makes the machine very comfortable to operate. Despite the small engine, the mini dumper has plenty of power. As shown in the video, it was even able to pull a delivery van without any problems.
