I always get my kids to post stuff for me on local facebook market place.
I used to use Kijiji, they seem to eclipsed Auto Trader here in Canada.....but every time I listed something on those two sites I got nothing but scam replies. You know, the ones that are in foreign broken english asking you to put in shipping container and send and they will send cheque, LOL
Kubotas B2710, M6800, L6060 cab, Volvo EC excavator, 2 ZTRs and various implements.
I have used FB Market Place most recently, Craigslist and BOTH have scammers on them. Word of mouth and if you have Nextdoor that can be good. Some of the big tractor sites will allow a private owner to list with them. Do you have a place you can park it with good visibility and is safe?
In Canada you can try Kijiji. For your safety Kijiji now plays man-in-the-middle with all communications and obfuscates buyer and sellers from each other. It's like having the phone company purposely hiding all call display data to make it harder to block spammers/scammers.
Tractor House is one avenue as would be equipment trader. Tractor house has a fairly decent rate for the advertisement. They did a book value on mine when they called, I would say it was pretty much spot on from what I learded.
