As my sig shows, I have both a zero turn and a new 2920. I'm suffering from severe depression as I have only 6 hours on my new bota and blower since it refuses to snow in my zip code.
I owned 3 JD mowers - each seemed to cost twice what the previous one cost and only lasted half as long. The last JD mower I had was about $4,000 new from the JD dealer and after 3 years and about 60 hours on level turf, was a piece of junk. The steering was loose and the cut was uneven. I've learned my lesson on Deere.
Good luck
Mike
