It appears to me the OP wants one less tractor and is trying to sell it back to the dealer. In my experience it would be best to sell it privately.
Since we built here I've bought 5 tractors and sold 3 of them. Only one was "sold" to a dealer as a trade. When shopping for the
L3200 in 2012, the deal was made on the
L3200 for just under $16K cash. The salesman was aware I was replacing a
B7500, and was quite impressed with the condition of my company truck - and assumed the
B7500 was well kept. He asked if they could come to my place and check it out.
He worked up a number I was happy with. It was around $1K less than I planned on advertising it for. Being able to have it show as a trade saved me over $600 in taxes. I probably would have taken $1K less than asking price, so it worked out well.
The current
L4240 came home at the end of 2018, but we kept the
L3200 for about a year before listing it for sale. After using it for 7 years, it sold for a little more than $2,500 than I paid for it (with a few refurbed and homemade implements included in the deal).
EDIT TO ADD: Here's a "Family Photo" from the day when the
L3200 came and the
B7500 went.
