72-in. (183-cm) 7-Iron PRO Mower 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 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.

Mower rectangular leading-edge reinforcement

Dual-captured anti-scalp wheel

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

Cast-iron mower spindle

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.

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.

On select products, the modem reports the fuel level. On these products, an analysis of fuel consumption is available in the Operations Center Machine Analyzer Tool. Measuring fuel consumption enables you to address causes of excessive fuel use.

Diagnostic trouble codes (DTCs)

On select products, the modem transmits the trouble codes generated by the mower’s control units to the Operations Center. Addressing DTCs can reduce downtime and repair costs. For example, a low-engine oil pressure DTC can indicate an engine is low on oil. Addressing the issue can prevent costly downtime and repairs.

Service Advisor Remote

On select products, John Deere dealers can perform remote diagnostics, software programming, and adjustments without the cost of a service call.

26x12N12 as an ordering option code for Z997R Diesel with 60 in. and 72 in. (152-cm and 183-cm) Mower Decks

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.

Michelin X Tweel Turf

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.
