Neighbor bought one shortly after I bought mine. Being in his mid 70's he had some adjustment issues going from a steering wheel to the skid steer style controls. His main issue was forgetting which way to go with his levers to turn, slow down, stop........
He got a little close to the ditch, hit a bump and this set off a chain reaction. Ended up in the ditch, which in our neighborhood are 4 ft deep.
He got lucky and didn't get hurt. He also didn't get pinned and was able to crawl out. I happened by just after it happened, so I latched onto the mower with a tow strap and pulled it out of the ditch with the truck.
No damage except to his pride.
There's been a few other folks that have been hurt mowing along ditch edges in our area. County comes through, adds more gravel, then paves the road, all of a sudden that gentle slop you were used to is too steep for a mower.
On the street side of the ditch in my neighborhood, I used to be able to mow it with a rider or zero turn. Since they raised the road 8 inches, it's sketchy mowing with a push mower.
