Couple things about a log splitter. I have one that is NOT attached to a machine, and it splits both vertical and horizontal.

I would NOT want one on a tractor just because I need the FEL on the tractor to move the pieces of wood around to place on the splitter. Many pieces that I have are too big to pick up, and some, even tho they are 16" wide, if flopped over, I cannot pick them back up to roll them.

While it isn't recommended, I purchased a set of skidding tongs from Harbor Freight and use them to pick up rounds to place on the log splitter with the FEL on the tractor. I then split & toss the splits in the bucket, using the bucket to put the splits inside the storage shed where I then stack them.
