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.)

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
Center deck rollers and left wheel Center deck rollers and left wheel
Right-rear deck wheel Right-rear deck wheel

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
Strong, reinforced deck Strong, reinforced deck
Right trim-side wear guard Right trim-side wear guard

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. (4.56-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.
Extra convenience
Serrated-tread step Serrated-tread step

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:

  • Reliably powered by a universal joint shaft drive from the vehicle transmission
  • To a heavy-duty right-angle, cast-iron gearbox
  • To a dependable v-belt drive system

Extra reliability and long life are provided by cast-iron blade spindle housings:

  • Ductile cast-iron material provides superior impact strength.
  • Gusseted design puts reinforcement where it is needed.
  • Strength of cast iron protects against damage from blade impacts.
  • Easy access grease fittings are mounted at the top of the spindle shafts for convenience.
  • Grease pressure-relief valve minimizes seal damage from overfilling with grease and keeps debris from entering housing.
  • Chance of deck-shell damage is minimized with the 8-in. (20.3-cm) diameter housing and six mounting bolts that distribute loads and impacts.
  • Ability to be reliably rebuilt is provided by use of cast iron.
Ease of service
Quick-release belt cover Quick-release belt cover
Cast-iron spindle housing assembly Cast-iron spindle housing assembly

Minimal service requirements increase uptime:

  • 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.
  • Convenient spindle greasing with fittings at the top of spindle shafts are accessible through a hole in the top of the spindle/belt covers.
    • The center spindle is accessed by no-tools removal of the vehicle floor pan.
  • There is only one belt to service.

Z994R with 72-in. (183-cm) mower deck Z994R with 72-in. (183-cm) mower deck

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.
ROPS in upright position ROPS in upright position
ROPS in intermediate position ROPS in intermediate position

Foldable ROPS and a retractable seat belt are standard equipment:

  • Position adjustment pins provide a good grip and make changing the angle of the ROPS easier.
  • If operating in low clearance areas, the ROPS can be folded and secured out of the way. It can also be positioned in an intermediate position to accommodate machines equipped with a material collection system.
  • Under normal operation, the ROPS should be in the up position.
  • See Operator’s Manual for more information on ROPS.
ROPS in down position (similar vehicle shown) ROPS in down position (similar vehicle shown)
