How Wheels Work
For those who were wondering, the thing (my pallet with wheels that my brother made) works like this.
The empty wheeled pallet sits just inside the garage door (Butler the dog likes to guard the open door and watches to make sure we are doing the procedure correctly). The full or half full pallet of wood, this time kindling bundles are on another pallet on the front end loader of the tractor.
Mike with his keen sense of spacial dimensions, can set the full pallet on top of the wheeled pallet without bringing the tractor into the garage where the door frame would hit the top of the tractor. The loaded wheeled pallet can then easily be manually pushed farther into the garage where it is out of the way so at least 2 more pallets of firewood can be brought in and stored.
And I agree it does look like something that you might find in an Amazon warehouse except for those would have long handles to tug and pull merchandise around the floor. Handles would simply be a tripping hazard for this small space and pushing this pallet when full takes little more than gentle pressure to guide it out of the way.
