My sister's husband was killed two weeks ago, and I used my late brother-in-law's zero turn mower to help my sister get her yard in shape last Saturday. I don't own one of those expensive mowers and I had never used a zero turn before, so my son made fun of me for going so slowly when the machine would have run MUCH faster if I had pushed it.

A lot of guys do mow very fast on those zero turns, but it seems like all the bumps and vibration from even a fairly smooth yard would shake the mower to pieces very quickly.

How do the bodies & frames hold up over time with all that fast bumping and shaking?
