Talk to people that have the ferris and the hustler. Ask the owners about out of pocket expenses to keep the mowers in working orderafter 2 years. The ferris rides nice, but look at all those moving parts, lots of bolts and bushings. Too much crap to trip over when trying to get on and off it.
K.I.S.S (Keep it simple stupid)
Drive them both--compare price, warranty, dealer, serviceability, features, and Hustler will win you over.
