I've parted out a few 110s and 200 series GTs in the past mostly on eBay and have done pretty well. I currently have a 110 and a 210 that I am parting. I had 8 listings this past week for parts from a 110 and only two sold and they sold for almost nothing.......one was the speed variator handle assembly in good working condition and it went for $2.45, in the past I got over $20 for one in similar condition. Is this just a bad time of year to sell parts for them because it's the end of the mowing season? I know the economy sucks but it sucked when I parted out the last two JDs and I didn't have this problem......I guess it's all in the timing.
BTW I don't just part these wonderful machines....if it's worth it I fix and keep some, resell others. I have a 216, 175 and Scott's 1642 that I use, two 111s that I'm reselling and a 110 and 210 that I'm parting. I have some other makes as well but really like the color Green the best.
