FEATURES
COMMERCIAL-QUALITY V-TWIN AIR-COOLED ENGINES WITH EFI POWER THE ZTRAK MOWERS:
Vanguard 61A6 33 hp (24.6 kW) gross at 3600 rpm (Z965M and Z965R)
Vanguard 61G8 40 hp (29.8 kW) gross at 3600 rpm (Z985R)

ENGINE FEATURES INCLUDE:
Air-cooled for minimum maintenance and maximum reliability
Standard cleanout ports for easy access to remove debris collecting in cooling fins
30-amp alternator
Complies with strict Environmental Protection Agency (EPA) and California Air Resources Board (CARB) emission standards without loss of horsepower or torque.

EFI WITH ELECTRONIC THROTTLE CONTROL
Electronically adjusts the supply of both fuel and air, responding instantaneously when the mower transitions from light to heavy mowing.
Unlike mechanical governors that droop under load, torque rises while maintaining constant full-throttle engine speed.
Productivity and cut quality are improved because the mower blades keep turning at full speed, delivering optimal cut quality and dispersion of clippings.
Immediate starting in hot or cold ambient temperatures or after long periods of seasonal storage
No choke linkage for the user to operate
Higher reliability with the elimination of vapor locking, misfiring, run-on, and after-bang
Automatic altitude compensation
Delivers fuel precisely for added efficiency
Reduces the potential for plug fouling

V-TWIN DESIGN
Fast starts
Smooth operation

OVERHEAD VALVES
More horsepower and torque per cubic inch of displacement
Better fuel efficiency

ALUMINUM CYLINDER BLOCK
Effectively dissipates heat to extend engine life
Lightweight and strong construction

FULL-PRESSURE LUBRICATION WITH FULL-FLOW FILTER
Reduces engine wear by ensuring proper lubrication, even when operating on hillsides or uneven terrain
Filtered oil reduces risk of contamination for increased engine life for increased engine life
Oil cooler helps keep engine at optimum temperature

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.

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, OPERATION, AND DEPENDENT ON LOADS AND OPERATING CONDITIONS, FUEL CONSUMPTION FOR Z955M AND Z955R ZTRAK MOWERS:
7Iron PRO side-discharge: 1.3 U.S. gph (4.9 L/hr)
FastBack PRO rear-discharge: 1.1 U.S. gph (4.2 L/hr)

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.
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.

COMMERCIAL MOWER DECK
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.

FASTBACK PRO REAR-DISCHARGE MOWER DECKS
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.)*

*NOTE: Operators maintaining turf outside of target areas are encouraged to evaluate rear-discharge dispersion through a cut quality demonstration to ensure satisfaction.
