I use a four wheel drive tractor with a grapple on the loader. Sure is handy, we used to use to chain them to the bucket with three hooks welded on the bucket. I know I need a super splitter more than anything else.
I was over in NE Oklahoma the other day and saw some of the most consistent size firewood I've ever seen. I mean it was perfect, even stacked out perfect, it was a little mom and pop store with prolly 40 cords stacked out for sale. I had to find out how they did it. I was envious of how much better their product looked. I pulled in and asked what they used......
a Super Split was what they used. If the tax man is nice, one will be ordered, actually prolly will order one regardless.
This coming season I think I'm going to try to palletize and band some wood just so I can load it faster and with the loader rather than having it hand loaded for delivery.
I think one of the best ways to increase productivity is to make sure you go to the woods prepared. We carry a box full of any basics so we never have to shut down. Xtra bar nuts, circle clips, chains, one extra flippy cap, xtra spark plug, xtra chain plenty of mix and bar oil, we also carry a couple xtra bars under the seat. We take lunch when more than three or four miles from town. Bottle of charcoal lighter in the truck and kitchen matches to start a fire when it is real cold out or when we decide to cook polish sausages for lunch.
The trick is keep going and only take a couple of short breaks, the longer you sit the harder it is to get back to it.
