7-Iron PRO mower decks have demonstrated quality, performance, and durability. They deliver a high-quality cut in diverse conditions.

Key features of the 7-Iron PRO mower deck:

• Deck is forged from 7-gauge, 0.179-in. (4.6-mm) steel to minimize the number of welds and provide a smooth underside with fewer sharp corners for reduced material buildup.
• Significantly fewer welds on the deck shell to wear or break - it is forged from a single sheet of steel rather than multiple fabrications. An anti-skid step on the deck provides easy machine mounting.
• Extra reliability and long life with cast-iron blade spindle housings.
• Higher blade tip speed than many competitors - approximately 18,500 fpm (5,639 m/min) for more blade cuts per inch mowed.
• A deep-deck design of 5.5 in. (14 cm) delivers excellent airflow so material can be processed quickly and efficiently.
• The wider and higher discharge opening provides even clipping dispersal for an excellent finished appearance in all conditions.
• Quick-release belt covers do not require tools or the removal of a ring clip; just lift one corner of the cover and rotate it slightly to remove.
  • A hole in the deck tab is provided for use of an optional ring clip for extra security, if desired.
  • This makes it quick and easy for you to clean out trash that may collect around the spindle sheave.

• Deck has rectangular leading deck edge reinforcement and the rounded corners of the forged deck help distribute impact stress to reduce the potential of damage when the mower contacts trees, rocks, curbs, and other fixed obstacles.
• Dual-captured front and rear anti-scalp wheels provide deck flotation over even the toughest terrain.
• Three 1-in. (2.5-cm), cold-forged spindles are heat-treated for strength without bulk and are supported by ball bearings, providing reliability and performance; spindle housings are ribbed cast iron providing both excellent strength and heat dissipation.
• The trim edge of the deck is equipped with a bumper that provides great abrasion resistance to protect the machine and the property.
• The front edge is raised above the blade plane to allow even cutting of tall grass and is reinforced with a square bar for durability. The front baffle has been redesigned to better manage airflow and control clippings.
• Three spindle grease fittings are accessible from the top.
• Blade overlap is 1.6 in. (40.6 mm), nearly 0.79 in. (20 mm) greater than previous decks, to reduce striping between blades.
• Quick-change, cutting-height adjustment.

Extra reliability and long life with cast-iron blade spindle housings

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.

The deck step safely aids the operator's entrance and egress from machine.

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.

Commercial-quality deck design

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.

Level cut

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 setting (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.

Heavy-duty components for long life

These rear-discharge decks are designed to stand up to heavy-duty commercial use:

• Superior strength and durability come from a 7-gauge, 0.179-in. (4.6-mm) steel deck.
• Experience extra strength and long life with a fabricated deck design that is formed, welded, and reinforced for extra protection from damage.
• The front of the deck is protected from damage by a 1.5-in. (3.8-cm) tall by 0.5-in. (1.3-cm) thick solid steel bar welded to the mower deck for additional strength.
• Both sides of the deck have bumpers that are made from compression molded ultra-high molecular weight (UHMW) polyethylene plastic.
  • The bumpers provide great abrasion resistance to protect the machine and the property.
  • Additional strength is provided by a 0.5-in. (1.3-cm) by 0.5-in. (1.3-cm) thick solid steel bar.

Foot platform isolators provide the operator with added comfort:

• Vibration to the legs and feet is reduced.

Brake & Go starting system

The Brake & Go starting system is a John Deere exclusive. This feature makes the starting process on all ZTrak™ mowers easier, while also making it possible to remove two interlock switches from the machine.
 
The Brake & Go starting procedure helps a novice operator look and feel like a professional. To start the machine, the parking brake must be engaged. It does not matter whether the power take-off (PTO) switch is on or off, nor does it matter if the control levers are pulled in or in the out position.
 
As long as the parking brake is engaged, the machine will start. When the parking brake is applied, the control levers cannot be moved to the forward or reverse positions.

Adjustable levers

The motion control levers have two height positions and can also be adjusted forward or rearward within the slotted holes. The levers should be adjusted so the operator can achieve a full range of control operation comfortably.

Tracking adjustment

The easy-to-turn (from-the-seat) tracking adjustment allows operators to keep their mowers straight and able to produce professional striping results.

Onboard storage and cup holder

Several storage areas are provided on the ZTrak machines. A convenient cup holder is also available.

Right-hand control panel

The controls are grouped together on the right console, providing one central location for:

• Rocker-type PTO switch
• Height-of-cut knob with transport lock
• Key switch
• Hour meter (carbureted models) or display panel (EFI models)
• Throttle
• Separate choke control
  • Easy choke operation yields less fouling of plugs
  • No choke required for the electronic fuel injection (EFI) models

Easy-to-operate height-of-cut adjustment enables on-the-go changes

An easy-to-use cutting-height lift system allows the operator to adjust the mower deck height with no tools and minimal effort. The easy-to-grip knob allows operators to dial in the desired height of cut (HOC).

Cutting height can be adjusted from approximately 1 in. to 5.5 in. (2.5 cm to 14 cm). Each increment on the knob adjusts the HOC approximately 0.25 in. (0.64 cm). The deck can also be raised and locked in a transport position to provide maximum ground clearance when moving the machine from one area to another.

The transport lock function allows the deck to be returned to the previous HOC after being in the transport position:

• Use the foot-lift pedal to lift the deck and engage the transport lock.
• Rotate the knob to adjust from 1 in. to 5.5 in. (2.5 cm to 14 cm) in 0.25-in. (0.64 cm) increments.

This design increases productivity by allowing operators to change the cutting height without having to leave the seat.

The Z900 ZTrak Mowers with EFI engines are equipped with upgraded electrical systems that power a modern display panel and speed trouble shooting.

 

The display panel assists in operating the mower and alerts to problems to reduce downtime and repair costs. The display panel includes:

• Hour meter
• Fuel level
• Engine speed
• System voltage
• Low engine oil-pressure indicator
• Starting interlock indicators for power take-off (PTO), operator presence, and park brake

The hydrostatic drive included with the Z900 Z Trak Mowers features two 13-cc (0.8-cu in.) unitized hydraulic pumps combined with commercial-grade, heavy-duty, 13-cc (0.8-cu in.) wheel motors into a single unit. The drive units feature cross porting, where the hydraulic fluid from the side doing the least work is filtered and then fed into the input of the side doing the most work. This ensures that the coolest fluid is going into the side working the hardest in order to provide the best performance during extended hillside operation in the same direction.

One pump and one motor drive each wheel on the Z900 ZTrak™ Mowers. This provides several benefits:

• Exceptional cooling in high load conditions
• Easy-to-check level and refill hydraulic oil
• Opens up access under the seat

The design of the Z900 Series makes many service components reachable and easily accessible from the ground.

• Large, open engine compartment at the rear of the machine provides convenient servicing and ensures the engine heat is directed away from the operator.

All ZTrak™ Mowers come with a maintenance label that is conveniently located inside the right-hand console. The label is written on English and Spanish languages and includes daily service check points, approximate fluid capacities, and tire pressures.

Quick response (QR) codes link to owner information web pages

To speed access to owner information web pages, a QR code is printed onto a product identification number (PIN) label located near the onboard storage. The owner information web pages that include links to:

• Safety and how-to videos
• Operator’s manuals
• Parts catalogs
• Maintenance reminder sheets
• Attachments
• Warranty statements

Diagnostics

On Z920M, Z930M, Z950M, Z960M, Z950R, Z970R models, the hour meter shows the number of hours the machine is run when the key switch is in the on position. It only counts the hours the engine is actually running. Machine diagnostics are the first step of a monitoring system to help operators quickly diagnose common downtime issues. A trouble code light is included on the hour meter.

 

Use of the hour meter and service interval chart helps determine when the machine will need service.

The Z955M, Z965M, Z975M, Z955R, Z965R, and Z985R EFI models include a modern display panel that speeds trouble shooting by providing error codes, system voltage, and circuit continuity tests that can report switch functionality and circuit continuity in seconds, without tools. These models are also equipped with a Service ADVISOR™ J1939 port to speed dealer diagnostics.

The spacious operator station has been designed for comfort, visibility, and ease of use:

• Getting on and off is easy with the flat operator platform.
• Convenient-to-use controls located close to the operator are color coded and designed for easy identification and operation.

The ROPS and seat belt work in conjunction to provide a protective zone around the operator:

• It reduces the operator’s risk of being crushed under the vehicle should it overturn.
• When used with the seatbelt, the ROPS can reduce the severity of injury in the event of a rollover.
  • Use of the seat belt is recommended when operating with ROPS in the upright position.

Foldable ROPS and retractable seat belt are standard equipment:

• Position adjustment pins provide a good grip and make changing the angle of the ROPS easier.
• The ROPS can be pinned in an intermediate position to accommodate machines equipped with a material collection system.
• Under normal operation, the ROPS should be in the upright position.
• See Operator’s Manual for more information on ROPS.
• Door height of most garages will accommodate the machine with ROPS in the raised position.

Michelin is a world leader in tire manufacturing and technology. This airless radial tire solution is an industry first for John Deere, which provides an additional advantage to John Deere customers.

Advantages of the Michelin X Tweel Turf include:

• Mowing performance is improved.
  • Rutting is reduced because the Michelin X Tweel Turf has more support across the surface for improved flotation and better ground contact.
  • Unique energy transfer within the poly-resin spokes reduces the bounce associated with pneumatic tires.
  • Excellent curb climbing is possible due to the Michelin X Tweel Turf construction and flexibility.
  • More consistent cut quality is achieved because inconsistent tire pressure is eliminated.
• Uptime is improved.
  • 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 for durability.
• 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.

NOTE: In some cases, different size Tweel tires are required depending on the mower deck size.
