Thank you all for derailing my thread, lol.
Anyway I went and spent some time in a B2650 Cab and 2 things happened. 1st my foot fell off the HST pedal and temporarily got wedged between the door and pedal, not cool and yeah I have big feet and was wearing work boots. 2nd when I was sitting on the seat I realized there was no room for my dog/co-pilot. So a Kubota cab machine is out for me as the L3560 is too big for my needs.
Side note: I did some research on what my BX25D is worth and it looks like I should be able to sell it for $12-14k.
yeah i got the 2650 not a fan of the treadle pedal either. What I have learned that i like is to cock my heel left towards the drivers door, and pivot back and forth and it seems to work. As far as passengers and size of dog, i dont think your going to find anything that will fit all of that until you go much bigger
