Only one problem, you need some stakes on that so you can put more than an arm load. This machine should be able to hold roughly a cord and a half looking at the size of the bunk, but now ya only have about 1/3 of a cord at best maybe 1/4, some decent stakes and you're uping production by about 5-6×, but it's a dandy little machine.
How many logs do you want to carry? Plus, I'm pretty sure this is an advertisement video, not a torture test. I bet the machine will hold more logs if required.
