Meet the Spartan RZ! Packed with the Tuff Torq 400 with steel gears and charge pumps, 22” Carlisle Turf Armor bias ply tires plus more commercial components, the RZ really competes on the residential and commercial level. Available with 54" and 61" deck size options and three engine options, the Briggs 25 hp, Kawasaki FR691 23 hp, and the Kawasaki FR730 24 hp. The RZ has the most commercial DNA for a residential price, period.
