The ZTrak Z900 Mowers are equipped with one single-fill, top-draw fuel tank:

11.5-U.S. gal. (43.5-L) capacity enables operators to mow all day without refueling.
The fuel gauge makes it quick and easy to see how much fuel is in the tank.
Top draw provides added safety.
A large fuel-filler neck is angled to make it easy for an operator to complete the fueling process.

Under normal conditions, load, and operation, fuel consumption for the Z900 ZTrak Mowers is 1.5 U.S. gph (5.7 L/hr) to 2.2 U.S. gph (8.3 L/hr), depending on the horsepower and conditions.

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 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 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.

Onboard storage

Cup holder

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

Brake & Go starting system

Parking brake pedal (Z900R Series)

Parking brake lever (Z900 E and 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.

Tracking adjustment

Throttle
Separate choke control
- Easy choke operation yields less fouling of plugs
- No choke required for the electronic fuel injection (EFI) models

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.

Field-installed propane conversion kits for commercial walk-behind mowers, QuikTrak™ mowers, and commercial ZTrak™ mowers

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:
