You know that's a great idea a bump stop so to speak to help know/feel that point. I've really gotten used to it now and I just use a light touch, I allow the sticks to fall to N basically and gently with finger pressure pull back to engage brakes.
I'm considering some type of mechanical or hydraulic brake setup on the two driven jack shafts that are driven from the transmission but drive the axles. A hand lever on each control stick and somehow tie in a park brake ratchet handle as well.
That would allow an optional brake for turning and stopping/slowing down and parking. To me that would be the best with your idea of a bumper as well.
I'll be looking at that idea of a rubber bumper. I just may have some material for that too..not too hard or soft...
If you check out my other videos on youtube you'll see some stuff regarding the transmission how it works etc and driving video...I need to have a partner video this for me while I drive slowly to depict what's going on LOL
There is a thread in transmission section about a Hagen transmission...video IIRC is posted there too and quite a bit of info, there are a couple of machines made with this transmission, some AATV like Newt the Bold and one or two others and a Ridgerunner snowmobile and it is a hell of a neat unit too as far as transmissions go.
Thanks for reading
