These are the pictures of the splitter.

As you can see you only need to drive on the back a couple feet to push the tab in the ground and the rest of the tracks hold the dozer from sliding back. I only had a small piece of wood there but it easily pushes large chunks. You can stand beside the dozer or sit on it and run the blade as fast as you can go.

We use a Backhoe to split, I think your's would be easier, just roll them in...
