Ray with the Husqvana , I would not like to put them on sloping ground because they are narrow and high, the fact you had the high side wheel loosing traction is not a long way from it tipping over and that can get ugly. This is where the Deutscher comes into its own, low, flat and wide, and by fitting a flat seat you can lower the center of gravity even more. I wouldn't give up on it, I would improve it to make it fit for your purpose. If you really wanted to you could fit a pair of discs to the front wheels,or even with a bit of ingenuity you could fit them to the rear. I moved the gearshift to the right hand side so you don't have this setup with 2 levers on the one side. I haven't tried fitting a longer arm on the steering to reduce the travel arc of the tiller but that might work, or as I said a chain driven steering wheel setup
