The Z915E is powered by an air-cooled, vertical shaft engine:
Engine features include:
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:
There are two seating options available on the E Series,
The deluxe comfort seat is standard on all Z900 Series models:
The deluxe comfort seat with armrests and isolation is available on the E, M, and R Series. This seat includes a fore/aft seat slide that reduces vibration and increases operator comfort. The benefits of the fore/aft seat slide include:
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.
The ZTrak™ E Series Mowers are equipped with a side-discharge, 7Iron II mower deck.
7Iron II mower decks have demonstrated quality, performance, and durability. They deliver a high quality cut in diverse conditions.
Key features of the 7Iron 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.
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. 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.
John Deere leads the commercial zero-turn mower industry with use of the Michelin X Tweel Turf technology for the ZTrak Z900 Series 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: Tweels are not compatible with the ZTrak Z997R Diesel.
NOTE: Different size Tweels are required depending on the mowing deck size. 72" decks require a different size Tweel than the 54"/60" decks.
Michelin, X, and Tweel are trademarks of Michelin North America, Inc.
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 hourmeter 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 hourmeter.
Use of the hourmeter and service interval chart helps determine when the machine will need service.
An exclusive two-year, unlimited hour/three-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.
An exclusive two-year, unlimited hour/three-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.
