Draw a vector diagram.

When the tractor is on the incline the vector at the center of mass (CM) moves downhill whereas, the NF vector doesn't. The front wheel vector becomes 'uphill' with respect to the CM vector and thus providing no resistance to a rollover. However, with a WF the downhill front wheel remains 'downhill' with respect to the CM vector and therefore continues to provide resistance to a rollover.

When the CM vector moment exceeds the sum of the vector moments from the downhill wheels the roll over is completed.
