I bought a new Hustler Z diesel about 3 years ago after looking at every zero turn available in this area. I wanted a diesel powered commercial grade mower and that is what I bought.
I researched down to the individual component level on the hydraulic pumps, motors, filters and coolers........I looked at Hustler, Bad Boy, Scag, Toro, X-Mark, Dixie Chopper, cub cadet, Kubota, Grasshopper and probably a few I have forgotten.
The Scag was nice, and I looked hard at it......but it was overpriced for what you got.......many brands, including scag, share the same pumps, hydraulic motors and engines.....it came down to paying extra money for the Scag name.
I narrowed my choice down to Bad Boy and Hustler.........Hustler has the best warranty in the business.....and the best steering.......the deck is much better built than most and the deck height adjustment is simple and rugged.......Hustler has been in the zero turn game longer than anyone else.
I also frequented commercial landscaping forums like Lawnsite and did a lot of reading......didn't take long to find out how well Hustler takes care of problems.
And, yes, it has 2 cup holders!
Best part......It cut my mowing time in half........I have never regretted the purchase.
