The Z915E is powered by an air-cooled, vertical shaft engine:
Engine features include:
ZTrak™ Z900 Mowers are equipped with a dual-element, canister-style air filter, easily accessible from the rear of the machine without tools.
The ZTrak Z900 Mowers are equipped with one single-fill, top-draw fuel tank:
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.
The ZTrak™ E Series Mowers are equipped with a side-discharge, 7-Iron II mower deck.
7-Iron II mower decks have demonstrated quality, performance, and durability. They deliver a high-quality cut in diverse conditions.
Key features of the 7-Iron II mower deck:
The Z915E is available with a choice of mower decks:
The Z915E uses a vertical-shaft engine. The power take-off (PTO) clutch is located on the bottom of the engine with the belt extending from the clutch to the mower deck, which is turned on and off by an electromagnetic clutch.
There are two seating options available for the E Series, both of which are factory installed:
Each seat has the ComfortGlide fore/aft suspension system that gives superior ride comfort over uneven areas:
The deluxe comfort seat with armrests is standard on all E and M Series models:
The deluxe comfort seat with armrests and isolation is available on the E, M, and R Series:
Two-lever hydrostatic control provides the following:
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.
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.
The easy-to-turn (from-the-seat) tracking adjustment allows operators to keep their mowers straight and produce professional striping results.
Several storage areas are provided on the ZTrak machines. A convenient cup holder is also available.
The controls are grouped together on the right console, providing one central location for key switch, throttle, PTO engagement, height-of-cut, diagnostics, and hour meter.
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:
This design increases productivity by allowing operators to change the cutting height without having to leave the seat.
An exclusive 2-year, unlimited hour/3-year, 1200-hour (whichever comes first) bumper-to-bumper warranty is standard for all John Deere E and M Series Mowers. The warranty is best in its class and places John Deere at the forefront of commercial mowing. It is also hassle free, with one company handling all of the paperwork.
NOTE: 36 months or 1200 hours, whichever comes first. For the first 24 months, there is no hour limitation.
Mowers decks are evaluated by the manufacturer (John Deere Turf Care) and conform to American National Standards Institute (ANSI) B71.4 2004 safety certification specifications for commercial turf care equipment.
An exclusive 2-year, unlimited hour/3-year, 1500-hour (whichever comes first) bumper-to-bumper warranty is standard on all John Deere R Series mowers. The warranty is best in the industry and puts John Deere at the forefront of commercial mowing. It is also hassle free, with one company handling all of the paperwork.
NOTE: 36 months or 1500 hours, whichever comes first. For the first 24 months, there is no hour limitation.
The durability features of the frame are as follows:
A steel rear bumper provides protection for the machine. The bumper is made of two pieces, making it easy to remove and install when using a material collection system (MCS).
A rear hitch can be added to the steel bumper for towing purposes. ZTrak E, M, and R Series Mowers can tow up to 400 lb (181.4 kg).

The hydrostatic drive features two 13-cc (0.8-cu in.) unitized hydraulic pumps combined with commercial-grade, heavy-duty wheel motors into a single unit.
One pump and one motor drive each wheel on the ZTrak™ E and M Series Mowers. This provides several benefits:
John Deere provides the commercial mower industry with the Michelin X Tweel Turf technology for Commercial ZTrak Mowers:
Michelin is a world leader in tire manufacturing and technology. This airless radial tire solution is an industry first for John Deere, which provides an additional advantage to John Deere customers.
Advantages of the Michelin X Tweel Turf include:
Heavy-duty construction provides the ultimate in performance and reliable operation:
NOTE: In some cases, different size Tweel tires are required depending on the mower deck size.
The ZTrak E Series Mowers with 48-in. (122-cm) mower decks come with 24x9.5-12 4 PR drive tires. E Series Mowers with 54-in. (137-cm) and 60-in. (152-cm) decks come with 24x12-12 4 PR drive tires. All E Series Mowers are equipped with 13x6.5-6 front pneumatic caster tires for the following:

The design of the Z900 Series makes many service components reachable and easily accessible from the ground.
All ZTrak™ Mowers come with an onboard maintenance chart that is conveniently located inside the right-hand console. The service interval chart gives necessary service intervals.
The hour meter shows the number of hours the machine is run when the key switch is in the on position. It only counts the hours the engine is actually running. Machine diagnostics are the first step of a monitoring system to help operators quickly diagnose common downtime issues. A trouble code light is included on the hour meter.
Use of the hour meter and service interval chart helps determine when the machine will need service.
On every John Deere ZTrak™ mower deck, there are three 1-in. (2.5-cm) spindles that are cold-forged and heat-treated for strength without bulk. The spindles are supported by precision ball bearings, providing great performance and reliability.
The spindle housing is made of aircraft-grade, ribbed cast aluminum on 48-in., 54-in., and 60-in. (122-cm, 137-cm, and 152-cm) decks, including Mulch On Demand™ configurations. This unique casting design embosses reinforcing gussets in the housing, which adds both strength and cooling surface area that stands up to commercial applications.
These spindles can be greased from the top and require no disassembly to reach. Grease channels provide lubrication to both bearings.
The spacious operator station has been designed for comfort, visibility, and ease of use:
The ROPS and seat belt work in conjunction to provide a protective zone around the operator:
Foldable ROPS and retractable seat belt are standard equipment:
|ROPS position||Height at top of ROPS|
|Upright||73 in. (185 cm)|
|Down||47 in. (119 cm)|
