Well lots of good info. I have emails Hydro Gear and Mulligans, hoping for a simple solution. I like my current Cub Cadet but its sounding like I really need to start looking for a decent used heavier duty newer model. I really like the steering wheel as it works great on our long swale, and the fabricated deck has held up under my abuse and the frame and from caster set up seems very sturdy. It sounds like heavier grade transmissions will draw more power and potentially run slower. I planned to upgrade motor a few HP when a repower is eventually needed but that's way off. Really sounding like a bit heavier duty machine with a steering wheel, 23 -27 HP motor, 50" - 60' fabricated deck and serviceable transmissions might be cheaper and easier. I like my current machine but the idea of being any slower or not having enough power at the PTO is concerning. Thanks for the input. I will keep looking for a trans upgrade but keep my out on facebook for options.
