I have a Wallenstein FX65.
Probably just the right size for your tractor. (Personally, I wish I'd went one size bigger for mine, but it's still works great. )
There's several good companies that make them. Many here like Wallenstein, Farmi, and some Norse (?) and a few others.
I like the trailer hitches that come with the Wally's, the ratcheting lock (versus a band brake), and the protective cage (which I consider a must).
Some may say why spend so much for a skidding winch, when other means will work, and for so few trees, but:
1) Once you have one you will find yourself using it for other things. (Firewood cutting? Pulling over trees (leaners), pulling vehicles, etc...
2) They're hard to find on the used market, so you can always resell when you're project is done and recoup most of your money.
