72-in. (183-cm) 7-Iron PRO deck shown

The ZTrak™ M and R Series Mowers are equipped with either a side-discharge or Mulch On Demand™ 7-Iron PRO deck.

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 stamped 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 stamped 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 – 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.

Mower rectangular leading-edge reinforcement

Dual-captured anti-scalp wheel

• Deck has rectangular leading deck edge reinforcement and the rounded corners of the stamped 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 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.

60-in. (152-cm) Rear-Discharge Mower Deck

72-in. (183-cm) 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.

Compatibility

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

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

Propane conversion kit on a walk-behind mower

Dual propane conversion kit on a QuikTrak mower

John Deere provides application-specific Environmental Protection Agency (EPA) approved field-installed propane conversion kits for specific John Deere commercial walk-behind mowers, QuikTrak mowers, and ZTrak mowers. The conversion kits include all components required to convert the engines to operate on propane fuel. Single-tank or dual-tank brackets (depending on the vehicle) are provided for securely holding the propane tank(s) to the vehicle.

Propane tanks are not included.

An optional altitude kit is required when operating at altitudes above 2000 ft (610 m). The operator’s manual with the propane conversion kit provides further details. Parts must be ordered separately through John Deere Parts.

Propane facts:

• Propane is flammable and commonly used as a fuel.
• The molecular formula of propane is C3H8, and it is in the family of liquefied petroleum gases (LP gases). The other LP gases include butane, propylene, butadiene, butylene, isobutylene, and mixtures thereof.
• Propane is commonly available and has proven to be a dependable, safe, economical, and clean-burning fuel. It can be used as household fuel, industrial fuel, and fuel for internal combustion engines. Propane has been used as a fuel since 1910.
• At atmospheric pressure, propane boils at -44°F (-42.2°C), meaning it typically exists as a vapor. However, when contained under pressure, such as in a propane cylinder, it can exist as a liquid.
• Propane is naturally odorless, but includes an additive odorant, usually mercaptan, which gives it a distinct odor.
• Vapor propane is heavier than air, meaning it will settle in low areas such as along the ground or in drains.

 Advantages of John Deere propane conversion kits include:

• Reduced fuel costs up to 30 percent depending on fuel prices
• Lower emissions
• Reduced fuel-system maintenance
• Maintains John Deere warranty
• EPA and CARB certified
• May qualify for national and state rebate and incentive programs.

Propane tank mounting bracket options:
