One of my “crazier” builds.
12hp Briggs Flathead, Peerless MST-206.
Engine belt meets at the middle of the frame, then goes through a MTD Vari-drive pulley, like a jackshaft, to a rear belt for the transaxle. It is also tensioned to be in the highest ratio possible.
Radio, LED under-glow, 2 120 volt outlets, what more?
If that 12hp gets going to 4300 RPMs, you’ll be flying at 30 MPH!
