Ok I see now......... You have a vertical shaft engine. I was assuming you had a horizontal. The one in the video is horizontal.
That replacement Lil Engine posted is for a pressure washer, that's why is has the short shaft.
The easiest thing and the cheapest is go and buy a new mower with a 6.25 or 6.50 briggs engine on it. Mowers have the shaft that matches yours.
Pop the engine off the frame and mount it up on your splitter.[/QUOT
Great idea ill check online to see if they have the same specs. First ill go to brigs and Stratton website to see if I can get exact shaft dimensions of my old motor and shaft .Not sure if I'm measuring it right by the oil pan. I did have hydraulic hoses made up and ran off of my tractor ran it for a season until a couple of mechanics at the hydraulic shop told me I was gonna burn up my tractor pump which will cost a lot more than a splitter. THANKS FOR THE INPUT I APPRECIARTE IT.
