Fuel tank and filler neck

 

Fuel filler neck

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.

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

 

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.

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

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

Tracking adjustment

The easy-to-turn (from-the-seat) tracking adjustment allows operators to keep their mowers straight and able to produce professional striping results.

RIGHT-HAND CONTROL PANEL

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.

Comfort and convenience handles

The comfort and convenience package combines large, ergonomically angled control levers with specially padded grips to provide unmatched comfort and reduced fatigue:

• Keeps hands on the control sticks to minimize equipment damage and make them more comfortable over long operating days.

The control levers have built-in electronic controls to raise or lower the mower deck or disengage the mower blades.

Control buttons

The push button (A) on the left motion control lever raises the mower deck.

The push button (B) on the right-hand control lever shuts off the PTO.

Once the PTO has been shut off using the button, the PTO switch must be pushed down and pulled up again to engage the PTO.
