From 42" to 52", this is a good idea that keeps getting better - The deck size and hp increase with each larger Z-Series rider, but that's not all. The wheel base also increases and the broader mowers have bigger rear drive wheels with larger rims and less tire sidewall. These features are modified to maximize the hill climbing ability, reduce side shifting, and improve turf traction of each deck. Full floating deck suspension

- The Z-Series has a floating cutter deck suspended from the frame. This suspension system gives an even cut and smoothes out the ride at faster speeds. Anti-scalp rollers add another level of protection to avert scalping when you turn on the slope. The cut looks even better because the offset caster wheels reduce tracking.

Smooth hydrostatic control - Hydrostatically controlled zero-turning-radius lends the Z-Series its name. But these compact riders are more than just easy to maneuver. Sure, they turn and trim on a dime, but zero-radius-turning ability adds efficiency only if the mower rides smooth and controls easily, and that's where the Z-Series riders excel.

Up slopes, around trees and over curbs - The mowers' wide stance and oversized rear tires increase stability for easy turning and exceptional hill climbing and slope stability. The front-end design lets you climb curbs so easily you'll quickly forget they were ever a problem, which means they'll never again slow down your productivity.
