I've got a 25 year old 2165 with around 900 hours that I now use only for pulling a trailer and snow removal. I've been beating the heck out of it all this time by towing firewood and dirt in my 17 cu/ft trailer - not to mention mowing well over an acre. I'm amazed the hydro has held up this long.
Anyway, even though it still runs pretty good, I can't help but think the transmission is going to give up the ghost one of these days. What transmission did they put in these guys? Can you still get a replacement? And, lastly, how much would I be looking at? I know it's crazy to think about a new hydro for something so old, but I'm curious anyway.
