This is spur of the moment, but I have a Snapper 4250 tiller made for the 1650, 1655, 1850, and 1855 tractors. It is Cat 0 three point hook up and 2000 rpm input. The unit works great, is 100% functional, and I just used it to till the garden. The tines have some wear, but are very usable and it tills wonderfully. The PTO shaft is included. $600
If you are between Knoxville TN and Toledo OH, or close to I-75, I'd be happy to deliver or meet up. I'll be traveling up all night tonight, and traveling back tomorrow between noon and 8 p.m. I realize this is short notice for delivery, but if this would help you, call or text me at 865-567-3508 before 11 p.m. EST and I'll bring it with me.
