My pick is a John Deere, Ive worked on mowers for 20+ years. Get the better one not the L or D series. Ive got a customer that mows commercial with a X300 that has 1700 hours on it. I have another customer that has 2200hrs on a LX 277 which the X300 replaced.

Of course you have to remember some folks can tear up anything.

Majority of my repairs are from bad fuel and water.
