Enhanced productivity, safety, and trim ability with a Fastback™ PRO rear-discharge mower deck
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:
- Less chance of damage from objects being thrown from the mower deck
- Time savings with the ability to mow closely around fixed objects with either side of the deck
- A cleaner mowing experience by lessening the amount of debris that can blow onto the operator
A rear-discharge mower deck is ideally suited for:
- Schools
- Parks
- Playgrounds
- Traffic areas (city boulevards, roadsides, etc.)
- Areas with long, grassy spots that need to be cut, where you are not as concerned about wide dispersal of grass (park areas, roadsides, etc.)*
*NOTE: Operators maintaining turf outside of target areas are encouraged to evaluate rear-discharge dispersion through a cut quality demonstration to ensure satisfaction.
A large volume of material can be thoroughly processed with the deep-deck design:
- Unique baffling system is designed to reduce clumping and windrowing often associated with rear-discharge mowers.
- Efficiency is enhanced with baffles surrounding each blade to control material as it is moved to the rear.
- Material exits the deck quickly as the baffles are lower at the rear.
- Movement of material is controlled to minimize the likelihood that clippings are thrown onto unwanted areas.
- Less debris gets on the operator as material is directed to the rear and toward the ground.
- Debris is kept low and directed into the turf by the flexible rear shield.
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:
- Two wide front rollers at the center of the mower support the deck when necessary to prevent scalping.
- Wheels at all four corners protect the deck from scalping at the sides of the mower.
- Continued effectiveness results from wheels and rollers that are double captured for extra strength, which reduces the chance of damage.
- Height of rollers and wheels is adjustable to suit mowing conditions.
- Higher settings (shown in images) are used when mowing at lower cut heights and for rougher conditions at all cut heights where you want to reduce the chance of the wheels hitting the ground.
- Lower settings are used for higher cut heights and for helping to smooth out the mowing job.
- Mower cut height is adjustable from 1 to 5.5 in. (2.54 to 14 cm) in 0.25-in. (0.64-cm) increments from the machine operator’s station.

Comfort and convenience handles put controls at the operator's fingertips
The Z997R and Z998R Diesel ZTrak™ Mowers allow operators to be more productive by locating frequently used controls at the operator’s fingertips.
ZTrak Mowers include large, ergonomically angled control levers with specially padded grips and built-in electronic controls.
- Operators select ground speed and direction simply by moving levers forward or in reverse.
- A positive neutral lock position for the levers provides added safety.
- Wide-bend steering levers swing out easily for entry and exit from the operator platform.
To reduce operator fatigue and tailor control sensitivity, the control levers operate the hydrostatic transmissions electrically. These drive-by-wire controls reduce effort needed to operate the handles and enable features like LoadMatch™, which can slow the mower under heavy cutting load, providing consistent cut quality.
Standard comfort and convenience handles are built into the steering levers.
Z997R – The Z997R has three steering-lever buttons. The left steering lever has a button (A) to raise the mower deck. The lift button can be pressed momentarily to raise the deck over an obstacle. The left and right steering levers each have a yellow PTO button (B). Press both buttons at the same time to engage the PTO. Press either button to shut off the PTO.
Z998R – The Z998R has five steering-lever buttons. The Z998R includes the same buttons as the Z997R model, plus there is a button (C) on each lever to raise or lower that side’s E-Cut Wing Mower Deck. Similar to a garage door, each deck lifts or lowers when its button is pressed. On the Z998R model, when the deck raise button (A) is pressed all three decks are raised to clear an obstacle.
The blades on the wing decks automatically stop when the decks are raised. If the PTO is engaged, the wing decks automatically start when the wing mower decks are lowered.
The integrated park brake is automatically applied when steering levers are stowed outward and disengaged when the steering control levers are placed into the operating position.
The key switch and switches for auto throttle (A), center deck control (B), and transport (C) are located near the touchscreen display.
Auto throttle – When the PTO is off, the auto-throttle switch is used to adjust engine speed. Low speed is used when maneuvering the mower in tight locations like loading on a trailer. High speed is used for transport. When the PTO is engaged, the engine runs at full throttle, and the auto-throttle switch is used to limit maximum mowing speed. The low-speed position improves precision while trimming and high speed enables full mowing speed in open areas.
Center deck control – Used to shut off the center mower deck with the PTO engaged; useful when the operator wants to mow with one or both wing decks without the center deck creating noise and stirring dust.
Transport switch – Raises all mower decks to transport position or lowers them to mow at full width.
Full-color touchscreen display provides unprecedented control and information
The Z997R and Z998R Diesel ZTrak™ Mowers are equipped with an advanced 4.3-in. (10.9-cm) full-color LED touchscreen, which provides unprecedented control and information.
Similar to mobile device screens, the touchscreen contains multi-colored pixels. Unlike segment-based displays, a touchscreen can be extensively customized, which enables software-defined menus and supports multiple languages including English, Spanish, German, French, and Italian. The touchscreen is bright so it can be read in sunlight and backlit for low-light conditions.
The touchscreen is designed and tested to withstand the elements. It is IP66 rated, indicating it is dust-tight and protected from water.
The touchscreen provides the operator with:
- Mower deck status
- Stop, service, park brake, power-take-off, seat switch, and diesel particulate filter regeneration indicators
- Fuel level
- Hours
- Connectivity signal strength
The touchscreen can be used to adjust machine settings:
- Mow mode – Choose between eco, cut quality, and productivity modes
- LoadMatch™ – Slows the mower under heavy cutting load, providing consistent cut quality
- Maximum ground speed
The touchscreen can also be used for diagnostics.
The Z997R and Z998R Mowers are factory-configured with a single full-access user profile. Fleet operators may choose to tailor menu access to the unique needs of owners, crew supervisors, and operators. Each user is assigned a PIN that may be restricted from machine settings and diagnostic menus.
A mower can have up to three owner profiles. Owner profiles have access to the following settings:
- Display settings
- Mow mode
- Speed limit
- LoadMatch
- Service and diagnostics
- Factory reset
- Operator permissions
A mower can have up to 100 unique operator profiles, each with their own PIN that remembers their unique language and machine settings. Each operator-profile setting has access to the display settings menu. Based on the owner’s permissions, each operator may be given access to, or restricted from, accessing the remaining menus. For example, an owner may give crew supervisors and experienced operators access to more settings than less experienced operators.
Standard high-back, air-suspension seat keeps the operator comfortable
The Z997R and Z998R Diesel ZTrak™ Mowers include a standard air-suspension seat, which provides maximum operator comfort across a wide range of operator traits.

- The exclusive technology eliminates downtime and associated cost due to flat or damaged tires. Punctures and sidewall damage no longer result in downtime.
- Cost of operation is reduced.
- Cost of repairs and maintenance is reduced. One single unit replaces the current tire, wheel, and valve assembly. There is no need for complex tire-mounting equipment.
- No need to spend time checking and optimizing tire pressure.
- The need to purchase and stock plug kits and spare tires is eliminated, particularly for professional landscape contractors and government agencies who normally stock them.
- The tire tread will last up to three times longer than current pneumatic tires because automotive-grade rubber is used for the tread.
Heavy-duty construction provides the ultimate in performance and reliable operation:
- High-strength poly-resin spokes carry the load.
- Four-hole, heavy-duty steel hub easily bolts onto any Z997M and Z997R ZTrak Mower.
- Deep, open-tread design provides excellent cleaning and traction.
- Zero degree, high-tensile proprietary carcass provides great lateral stiffness while resisting damage from impact and penetration.
The Z997M and Z997R ZTrak Mowers are equipped with 15×6-6 flat free front caster tires that provide:
- Excellent reliability and uptime
- Low center of gravity to increase hillside mowing capability
- Caster wheels and caster wheel towers with sealed bearings for long life and easy steering
- Offset front caster wheels to help improve the inside corner-trim performance and reduce between-blade striping
A choice of rear wheel options is available for factory installation:
- 26×12-12 4 PR, square shoulder, pneumatic drive tires in base equipment for excellent traction, flotation, and curb climbing
- 26×12-12 Michelin X Tweel Turf airless radial tire technology option for a smoother ride and more uptime
