After searching for 2 years, I finally found a used logging winch in decent shape for reasonable money.
A guy in the next town over posted it 3 days ago and I jumped right on it.
Hooking up was helped by the 3ph telescoping lower arms.
Norse 450. Good size for the 6040.
As Oldpath mentioned, adding a hitch to pull a trailer can be handy. You can usually find a way to add one, but the method varies from brand to brand. My Uniforest 35E did not come with a hitch, but I noticed that a bolt-on hitch was included with their larger models. The channel to which they bolted was on my model, so all I needed to do was order the hitch and drill the holes in the channel that ran down the center of my which frame. (sorry, no picture of this one mounted)
I later decided I did not like the pin hitch. It did not allow enough flex when driving through ditches and waterbars, so I had a local fab shop use the factory hitch as a pattern, and make me a receiver hitch that mounted the same way. I ended up pinning it on, rather than bolting. It tends to rattle more now when going over bumps, but I can put it on and off in seconds, without any tools. I had this receiver tube made short, to reduce the cantilevered loads hanging off the back of the winch (not an issue when pulling my log splitter, but the tongue weight on my firewood trailer can get heavy at times). The short tube requires shortening my receiver inserts and redrilling the hole for the hitch pin, but those same inserts also fit the shortened receiver I had made for my Coot (an antique UTV I sometimes use for firewood or splitter hauling). Show here with an insert to use with a pin hitch, since one of my firewood trailers is set up that way.
I've seen pictures on here where people found a spot in their butt plate where they could safely cut a hole and weld in a receiver tube. This is nice because you don't have to have a lot of "hardware" hanging off the back of the winch, just a bit of receiver tube poking out. (I remove my receiver when doing a lot of winching or skidding, so I don't end up beating it up with the logs.) welding in a receiver tube was not an option for me, due to the center rib. I would have had to make the hole way off-center due to the rib and the location of the "works" on the other side of the butt plate.
If cutting a hole and welding in a tube is not possible on your winch, you could always weld some tabs or a piece of channel on and do something like mine.
