Maybe you need a driver? I saw a Peterbilt with a 425 Cat and too much traction put three full turns into a piece of 4" driveshaft tubing one day. It was bogged down in a muddy rice field and the throttle jockey revved it up and side-stepped the clutch. The driveshaft ended up looking like an hourglass.
