I have a Tool Tuff 3 point log splitter that is run off of the tractor hydraulics. Its based off of a 22 ton model. It depends on what your doing with it. I do not heat with wood, so I use it to split larger pieces so I can load them by hand into friends trucks.
- It is sloow compared to a normal 22 ton splitter. 1/2" Pioneer quick couplers are only good to 12 GPM so I cannot run the full 20 GPM my tractor is rated for. I think it would be much more tolerable at 20 GPM.
- The tractor takes up lots of room so you have to park a truck or trailer 90 degrees to it.
- It makes the tractor long, and therefor harder to navigate through the woods.
- I am running a 45 hp diesel engine vs a smaller gas engine, It would be more economical to run the gas engine.
- It ties up the tractor as I cannot be using the tractor to load split wood, or bring pieces to the splitter.
- It is one less engine to maintain
- It is easy to store as I just set it on the crate I made for the post hole digger.
- It is reliable. If I do not use it for months I have no issue as the tractor is used all the time and will start.
- You can back the tractor and splitter right up to large rounds so you only have to move them inches.
For my limited use its great and way better than a stand alone unit. I am an infrequent user and a stand alone unit would always need work. There is very little to go wrong. The tractor engine at 1000 RPM is quiet, it is plenty strong too. If you are splitting more than a cord a year I would get a stand alone. If your splitting less then a cord a year then a tractor mounted unit is great.
