The Michelin X Tweel performs like a pnuematic tire, but without the risk and costly downtime associated with flat tires and unseated beads. Never have to worry about air pressure.
John Deere's exclusive 7-Iron decks are 5.5 inches deep and 7-gauge sturdy, which explains why they're the strongest, most durable mowing decks in the industry.
The Z997R is powered by a 3-cylinder, liquid-cooled diesel engine with a gross 37.4 hp (27.5 kW) that meets U.S. Environmental Protection Agency (EPA) Final Tier 4 emission standards. The engine achieves Final Tier 4 compliance by using a diesel oxidation catalyst with diesel particulate filter (DOC/DPF) system.
The three-cylinder diesel engine features low noise levels, superior fuel economy, and a high torque reserve that provides plenty of power and performance.
Key features of the engine include:
The ZTrak™ Z997R Diesel Mower is equipped with a dual-element, canister-style air filter that is easily accessible from the rear of the machine without tools.
The Z997R Diesel ZTrak™ Mower is equipped with a single fuel tank, providing the following:
NOTE: The fill level is 1 in. (25 mm) below the bottom of the filler neck.
There are two side-discharge mower-deck options available for the Z997R Diesel ZTrak Mower:
On every commercial mower deck there are three 1-in. (25-mm) spindles that are cold-forged and heat-treated for strength. Spindles are supported by precision ball bearings that provide great performance and reliability.
Mower decks are shaft driven. Benefits of using this type of system include:

Mowers decks are evaluated by the manufacturer (John Deere Turf Care) and conform to American National Standards Institute (ANSI) B71.4 2004 safety certification specifications for commercial turf care equipment.
For professional landscapers and government municipalities requiring rear discharge placement of grass and debris, John Deere Fastback PRO rear-discharge mower decks deliver a commercial zero-turn mowing solution for both gas and diesel machines. Advantages of a rear-discharge mower include:
A rear-discharge mower deck is ideally suited for:

A large volume of material can be thoroughly processed with the deep-deck design:
The deck is suspended from and supported by the machine to provide a level cut. Mower deck wheels and rollers help smooth out the mowing job in uneven conditions and reduce the chance of scalping the lawn:
These rear-discharge decks are designed to stand up to heavy-duty commercial use:
Extra convenience and security are provided by a serrated surface that is welded to the top left corner of the deck, providing additional traction when entering and exiting the operator station.
Durability is designed into the mower blade drive system:
Extra reliability and long life are provided by cast-iron blade spindle housings:
Minimal service requirements increase uptime:
The Z997R Diesel ZTrak™ Mower is ergonomically designed to give the operator an enjoyable and comfortable ride while increasing productivity.
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.
The push button (A) on the left motion control lever raises the mower deck. The push button (B) on the right-hand control lever shuts off the power take-off (PTO).
Once the PTO has been shut off using the button, the PTO switch must be pushed down and pulled up again to engage the PTO.
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:
ComfortGlide fore/aft suspension gives superior ride comfort over uneven areas:
Service components are easy to see and access:
Hood has one central over-center type latch.
The hood pivots to make the hood easier to remove and install for ease of servicing the engine.
The durability features of the frame are as follows:
A cast-iron rear bumper is provided on the machine for rear protection. It also adds weight to give great hillside performance.
A rear hitch can be added to a 10-gauge, 0.135-in. (3.4-mm) steel bumper for towing purposes. ZTrak™ Z997R Mowers can tow up to 400 lb (181 kg).
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. The swash-plate bearings are roller-type versus ball-type bearings for a longer overall pump life.
The transmission module integrates the dual pumps and steering valves in one single housing. The pump is shaft-driven from the engine. An isolator ensures reduced vibration between the engine and the transmission module.
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 from Parker Ross, part of the Hydraulic Pump & Motor Division of Parker Hannifin®, 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.

Single-touch deck lift system is best in class:
The push button (A) on the left motion control lever raises the mower deck. The push button (B) on the right-hand control lever shuts off the power take-off (PTO).
Once the PTO has been shut off using the button, the PTO switch must be pushed down and pulled up again to engage the PTO.
The spacious operator station has been designed for comfort, visibility, and ease of use:
The ROPS and seat belt work in conjunction to provide a protective zone around the operator:
Foldable ROPS and a retractable seat belt are standard equipment:
The retractable seat belt is within easy reach of the operator for use when operating with the ROPS up.
ROPS are foldable to allow trimming, such as under trees or bushes:
The folding ROPS performance is certified at the date of manufacture according to ISO 21299.
Stabilizers reduce the amount of movement and noise in the ROPS.

Full height | 85 in. (216 cm) |
Down | 48 in. (122 cm) |
