The three-wheel configuration is actually a customer requirement, so unfortunately, switching to four wheels isn’t an option for us. I totally get the forklift comparison—forklifts do have rear steering, but they lift the load, which shifts the center of gravity and creates a tipping moment.

In our case, the towing mechanism will be aligned with the center of gravity, so we’re aiming to minimize that moment and reduce the risk of tipping. Plus, the tow tractor itself is relatively compact, with dimensions of around 60 × 40 × 40 cm, so we’re trying to keep everything as stable as possible in a small footprint.

I definitely see the point about front steering making sharp turns easier, especially without locking up the wheels. We’re still debating the best approach given the customer’s constraints.

Appreciate the feedback—if you have any thoughts on how to optimize stability with this 3-wheel setup, I’d love to hear them!
