Look on Craig's list for the following 2160, 2165, 2185, LT2180 they all make great organ donors. Probably a couple others also. 16HP Vanguard or 18HP Kohler CH.

Good call.

OP did you find source of the leak? New window in block?

I couldn't find the hole, but I olny took the passenger side heat shield off. I see what looks like a small crack but can't be sure.

Really frustrating because I just spent a bunch of money and time tuning it up. Guess it was more than her old heart could handle!
Is 1811 a big upgrade?
Any opinions on new cub zero turns?

Thanks! I was wondering this. There are a bunch out there and didn't know what to avoid.

Cub ZTR...prolly not any good unless you wanna drop $8k+ on one and then I would prolly go with a Kubota or Exmark. If the box store sells it, it is garbage!

I would just find a good motor and drop in it. The 1811 is the same tractor you have with a hydro lift and nothing else. The Mags were awesome motors in their day but looks like it's time to look for a Kohler Command of a Briggs Vanguard.

Where are you in Kentucky? There is a nice 1811 on Craiglist in Middlesboro Ky.

Crestwood, pretty good haul to there.
