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

54-in. (137-cm) 7-Iron PRO Mower Deck

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.

Superior impact strength provided by ductile cast-iron material.
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.

The operator can select the ground speed and direction control simply by moving levers forward or reverse.
Positive neutral lock position for levers provides added safety.
Brake & Go operator-presence system returns levers to the neutral position when the brake pedal is actively engaged.
Starting the machines is as easy as starting a car. It no longer matters if the control levers are extended out or pulled in, as long as the parking brake is engaged. Just turn the key and go.
Wide-bend, large-diameter steering levers swing out easily for entry and exit from the operator platform.

Brake & Go starting system

Parking brake pedal (Z900R Series)

Parking brake lever (Z900 M Series)

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.

Onboard storage and cup holder

Onboard storage

Cup holder

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

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

Mower deck height adjustment knob

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.

Durable, hydrostatic drivetrain including cross porting delivers better cooling and provides easy access

Heavy-duty ground drive

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

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.
