They didn't show the machine you need to load the logs on the infeed of the machine. Overall a pretty hefty investment. I have one of the small electric/hydraulic machines too and since I burn wood for my primary heat source it gets a pretty good workout. Daughter and son in law also use it for their house as they also burn wood primarily so up to about 16 cords a year between us.
Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.
