This is a hands-on PTO-shortening tutorial, not a sales or spec overview. The owner walks through measuring and cutting a four-foot PTO shaft down to roughly 35 inches to fit a 25A flail mower on a 4066R, checking driveline angles through full tilt-cylinder range, then test-mows along a property line as a first-run check. Best for owners doing their own flail mower PTO fitment, not shoppers wanting tractor specs or a buying overview.
