"You will almost always do better selling anything you own"
I agree. for years I bought, sold, repaired and traded in used riding mowers/tractors. I bought used stuff from a large dealer in larger town a few miles away and you would be shocked at what I would pay. Most don't figure on having much IF ANYTHING in used riding mowers, lawn tractors. I would often buy 3 - 5 for what you might expect to pay for one.
They get $75 per hour for their shop time. They had all the business they could take care of and would much rather have their techs working for cash then fooling with traded in stuff plus they didn't have to worry about taking yet another trade in and of course generally had to offer a 30 day warranty on used stuff and all the head aches associated with that.
