• Extra durability and mowing performance from 7-Iron™ PRO Side-Discharge decks pressed from a single piece of steel

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.

• Available Mulch On Demand™ deck

Key features of the 7-Iron™ PRO Mulch On Demand mower deck:

• Deck can be converted from a wide-open side discharge mode to a fully chambered mulching mode with a single move of a lever.
  • NOTE: Mulch On Demand decks are a balance between a side discharge deck and a side discharge deck with a mulching kit.
• 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. Anti-skid step on the deck provides for easy machine mounting.
• Mulch On Demand decks are superior to aftermarket chute blockers due to the movable baffles.
• Higher blade tip speed than many competitors - 18,500 fpm (5,639 m/min) for more blade cuts per inch mowed.
• 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.
• Deep-deck design of 5.5 in. (14 cm) delivers excellent airflow so material can be processed quickly and efficiently.
• Wider and higher discharge opening provides even clipping dispersal for an excellent finished appearance in all conditions.
• 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 reinforced with a square bar for durability. The front baffle has been redesigned to better manage airflow and control clippings.
• Dual-captured anti-scalp wheels provide deck flotation over even the toughest terrain.
• Three greaseable spindle zerks accessible from the top.
• 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.
• Blade overlap is 1.6 in. (40 mm), nearly 0.79 in. (20 mm) greater than previous decks, to reduce striping between blades.
• Quick-change, cutting-height adjustment.

• 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.)*

• Three seat choices with ComfortGlide™ fore/aft suspension offer exceptional operator comfort

There are three seating options available for the M Series, all of which are factory installed:

1. Deluxe comfort seat with armrests
2. Deluxe comfort seat with armrests and isolation
3. Fully adjustable suspension seat with armrests
