Powerful diesel engine for increased performance

The Z997R is powered by a 3-cylinder, liquid-cooled diesel engine with a gross 37.4 hp (27.5 kW). The unit meets U.S. Environmental Protection Agency (EPA) Final Tier 4 emission standards.

It is a high-torque, low-emission diesel engine for strong performance in the toughest conditions, with low vibration and noise levels – kept isolated with rubber mounts for a smoother operator ride. The engine offers superior fuel economy and a high torque reserve for plenty of power and performance.


Four mower deck options for the Z997R give superior performance in every application

There are four mower-deck options available for the Z997R Diesel ZTrak™ Mower:

  • The 60-in. (152-cm) 7-Iron PRO side-discharge deck is suited to a variety of mowing jobs, including trimming and grooming.
  • The 60-in. (152-cm) 7-Iron PRO Mulch On Demand mower deck can be converted from a wide-open, side-discharge mode to a fully chambered mulching mode with a single move of a lever.
  • The 60-in. (152-cm) rear-discharge mower deck is fabricated from 7-gauge, 0.179-in. (4.5-mm) steel for added deck strength and long life. It is ideally suited for areas where people are present.
  • The 72-in. (183-cm) 7-Iron PRO side-discharge deck is suited to a variety of mowing jobs, including trimming and grooming on larger properties.


Standard operator comfort and convenience package for ease of use

The Z997R Diesel ZTrak™ Mower is ergonomically designed to give the operator an enjoyable and comfortable ride while increasing productivity. The commercial cutter can select the ground speed and direction control simply by moving levers forward or in reverse, and the positive neutral lock position for levers provides added safety.

The comfort and convenience package includes large, ergonomically angled control levers with specially padded grips and built-in electronic controls to raise or lower the mower deck and disengage the mower blades.


Deluxe comfort seat is fully adjustable and includes ComfortGlide™ fore/aft suspension

The deluxe comfort professional-grade seat is included in base equipment. It provides the operator with an enjoyable ride by allowing the operator the ability to adjust the seat to their preference. It includes a 24-in. (60.9-cm) high-back seat with a suspension-reaction dial that adjusts vertical suspension for operator weight and a firm or soft ride. Armrests and the back angle are fully adjustable.

The ComfortGlide fore/aft suspension gives superior ride comfort over uneven areas: the seat can travel up to 2 in. (50.8 mm) fore and aft to absorb bumps for a significant enhancement to ride comfort.


Easily accessed daily service points mean less maintenance time and more working time

Frequently accessed service areas such as the air cleaner, radiator screen, and oil check and fill points can be easily accessed from the open engine compartment. An easy-to-remove rear engine service panel allows access to all engine service points for scheduled service or other maintenance work.

The design of the Z997R makes service components like the engine oil dipstick, oil filter, and fuel filter/water separator easy to see and access, and a large radiator coolant reservoir and fuel filter/separator reduce service requirements and increase uptime.

The floor panel is easily removed, without tools, to give access to the top of the mower deck for cleaning and service.

All mower deck blade spindle grease fittings can be accessed from the top of the mower deck.

Heavy-duty frame provides strength and durability

Attractive styling incorporates a roomy and uncluttered operator platform with adjustable footrest, seat, and steering control positions for different operator preferences. Other well-thought-out features further contribute to good looks and operator comfort.

The frame is made of heavy-duty formed and welded steel for strength and reliability. Cast I-beam caster arm and spindle assemblies handle the beating and pounding professional mowers receive.

Caster wheels are offset for optimum steering and mowing performance. Benefits include better inside-corner trimming performance and less chance of between-blade striping.

A rear hitch can be added to the steel bumper for towing purposes. The Z997R can tow up to 400 lb (181.4 kg).

Quality drive system provides longer life and less maintenance

The hydrostatic drive features a Kanzaki® DUP 17SB dual-unitized hydraulic pump. This dual pump, in a single housing, provides longer life and less maintenance than competitive units. The pump features a shaft-driven fan for added cooling and longer component life.

Two wheel motors are installed on the chassis to directly transfer power to both wheels. Commercial-grade, heavy-duty TG0310 18.9-cu in. (310-cc) wheel motors are also important components of the overall drive system efficiency.

Rigid hydraulic lines are installed between the hydraulic module and wheel motors for long life.

Mower deck height-of-cut adjustment is easy to use

The single-touch deck lift system is best in class:

  • No tool required for adjustments
  • Dial-in knob used in conjunction with push button to change the height of cut
  • Easy-to-use design for increased productivity by allowing change of cutting height from the seat
