ZTrak™ Z900 Mowers are equipped with a dual-element, canister-style air filter, easily accessible from the rear of the machine without tools.

• The filtration system pulls clean air from above the engine, in turn filtering out the dust that can damage an engine over time.
• Filters are extremely easy to change when required.
• Pre-cleaner provides more protection against contamination in dusty and dirty applications.

MOW ALL DAY ON A SINGLE TANK OF FUEL WITH EFFICIENT AND EASY-TO-FILL FUEL TANK

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 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.
