Z Master Z400/Z500


Commercial Zero-Turn Riders: Z Master mowers are designed to handle the demanding conditions of the landscape professional, and to deliver an immaculate after-cut appearance that can't be beat. Trusted by landscape professionals for years, these commercial-grade models continue to deliver outstanding performance and durability at a great value. Z400 series - 21 hp Kawasaki® OHV V-Twin engine with 48 in. 7-gauge deck.


Comprehensive Warranty: Model Year 2008 and Prior: 1 year limited, 2 year engine, hydrostatic and deck shell and 3 year spindle assembly. (Third year parts only). Model Year 2009: 4 year / 1,200-hour limited warranty, with limited lifetime frame warranty.


7-gauge Deck: Z400 Series decks are not only strong (see Deck Construction), but they deliver an immaculate after-cut appearance that can't be beat. Available in 48 in. and 52 in. cutting widths.


A flat, crisp cut with precision blades: 1/4 in. thick precision blades resist flexing to provide a flat, crisp cut. High-strength, heat-treated alloy steel survives impacts and provides resistance to the rapid wear commonly associated with abrasive conditions.


Convenience and Comfort: Operator controls are conveniently grouped in a single location. Steering levers are adjustable to accommodate a wide range of operators. A built-in cup holder is provided.


Rubber Discharge Chute: High performance 5/16 in. rubber discharge chute allows for close trimming without damaging chute or landscape structures. Patented design provides exceptional clipping dispersion.


Rugged Frame: A commercial-grade carrier frame, constructed of 2 in. x 2 in. x 3/16 in. tubular steel, supports the cutting deck and stands up to the rigors of professional use.


Deck Offset: Z400 Series cutting decks are offset toward the trim side in order to provide trimming capabilities that are superior to those of comparable compact ZRTs. The trim side of the deck is also reinforced by a rugged 1/2 in. x 1-1/2 in. steel wear guard.


Folding Rollover Protection System ROPS: A Rollover Protection System (ROPS), complete with seat belt, comes standard for operator protection in the case of accidental rollovers and tipovers. In situations where sufficient vertical clearance is not available, such as loading on an enclosed trailer, the ROPS can be temporarily unlocked and folded down.


The industry's toughest spindle assembly: Rigorously tested to ensure that it can survive impacts that would destroy lesser spindles. The cast iron housing, with a massive 9-3/8 in. diameter base, absorbs impact loads and distributes them across a broader area of the robust deck shell.


7-gauge, high-strength steel: Constructed of high-strength 7-gauge steel (50,000 psi minimum yield strength), the deck shell is extremely resistant to impacts and abrasion. At a full 5-1/2 in. deep, the deck has more than enough capacity to handle the most demanding conditions.
