I'm going to do a motor swap on my HT20 with a newer kohler command. I haven't figured out how to do the exhaust, but imagine the stock muffler from my HT20 will not find its way back on. This tractor has been garage kept since new and the muffler is on excellent shape, including the shield. Would anyone be interested in it? If so, what is a fair price? I will have other kohler parts and pieces as i do the swap. Just thought I'd inquirie before i start tearing it down (which i have tons of projects anyways). I may start pulling it apart next month if i don't get called back to work. I may part out my complete (partially restored HT23) to make room in the garage as well ad to help fund some other projects/keep afloat lol.
