While the math is correct that lowering the FEL to lift the front wheels and lifting the mower would have been the correct thing to do to add traction to the rear wheel I think all are in agreement on that but would that have made things better at that point.
The issue is when events start there is only time to react and not many mentally practice recovering from these types of accidents. The physics can get complex.
With the rear wheels siding and the front ones off the ground to transfer weight to the rear wheels who knows how it would have slid. We are taught to keep the nose pointed down by steering.
Monday morning quarterbacks can never be proven correct or incorrect because the game is past tense.
Thanks for all sharing those of us with steep slick hills can practice using all of the advice. NOT
I was mowing on a 45 degree dewy slope at 10 PM and rolled me and the push mower down into the parking lot. The mower was OK but I ripped the screws of my metal hip socket from my butt bone. That was nearly a $30K repair job and no one locally would touch the job so I had to got to Nashville to the Southern Joint Clinic.
It does not require a tractor to get hurt mowing.
