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:
- Mowing performance is improved.
- Rutting is reduced because the Michelin X Tweel Turf has more support across the surface for improved flotation and better ground contact.
- Unique energy transfer within the poly-resin spokes reduces the bounce associated with pneumatic tires.
- Excellent curb climbing is possible due to the Michelin X Tweel Turf construction and flexibility.
- More consistent cut quality is achieved because inconsistent tire pressure is eliminated.
- Uptime is improved.
- The exclusive technology eliminates downtime and associated cost due to flat or damaged tires.
- Punctures and sidewall damage no longer result in downtime.
- Cost of operation is reduced.
- Cost of repairs and maintenance is reduced. One single unit replaces the current tire, wheel, and valve assembly. There is no need for complex tire-mounting equipment.
- No need to spend time checking and optimizing tire pressure.
- The need to purchase and stock plug kits and spare tires is eliminated, particularly for professional landscape contractors and government agencies who normally stock them.
- The tire tread will last up to three times longer than current pneumatic tires because automotive-grade rubber is used for the tread.


Heavy-duty construction provides the ultimate in performance and reliable operation:
- High-strength poly-resin spokes carry the load.
- Four-hole, heavy-duty steel hub for durability.
- Deep, open-tread design provides excellent cleaning and traction.
- Zero degree, high-tensile proprietary carcass provides great lateral stiffness while resisting damage from impact and penetration.
NOTE: In some cases, different size Tweel tires are required depending on the mower deck size.
Tires deliver exceptional traction and maneuverability


The ZTrak M Series Mowers with 48-in. (122-cm) mower decks come with 24x9.5-12 4 PR drive tires. M Series Mowers with 54-in. (137-cm), 60-in. (152-cm), and 72-in. (183-cm) decks come with 24x12-12 4 PR drive tires. All M Series Mowers are equipped with 13x6.5-6 front flat-free semi-pneumatic caster tires for the following:
- Excellent traction, flotation, and curb climbing
- Low center of gravity to increase hillside mowing capability
- Caster wheels and caster wheel towers with sealed bearings for long life and easy steering
- Offset front caster wheels to help improve the inside corner-trim performance and also reduce between-blade striping
Michelin, X, and Tweel are trademarks of Michelin North America, Inc.

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:
- Exceptional cooling in high-load conditions
- Easy-to-check level and refill hydraulic oil
- Opens up access under the seat

The design of the Z900 Series makes many service components reachable and easily accessible from the ground.
- Large, open engine compartment at the rear of the machine provides convenient servicing and ensures the engine heat is directed away from the operator.


Onboard maintenance chart

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.
Diagnostics


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.


E and M Series 3-year, 1500-hour bumper-to-bumper warranty
An exclusive 2-year, unlimited hour/3-year, 1500-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 1500 hours, whichever comes first. For the first 24 months, there is no hour limitation.
R Series 3-year, 1500-hour bumper-to-bumper warranty
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.
Mower decks are safety certified

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.

The ZTrak™ M and R Series Mowers are equipped with either a side-discharge or Mulch On Demand™ 7-Iron PRO 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 stamped 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 stamped 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 - 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.


- Deck has rectangular leading deck edge reinforcement and the rounded corners of the stamped 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 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.

The deck step safely aids the operator's entrance and egress from machine.


The Mulch On Demand mower deck delivers unprecedented levels of productivity and versatility to commercial mower operation. With the ability to switch between side discharge and mulching operation with the flip of a lever as the operator mows, keeping most clippings out of landscaping features and where they are wanted is extremely easy.

![Mulch On Demand closed (latch standard on material collection system [MCS] equipped models only)](https://salesmanual.deere.com/sales/salesmanual/images/NA/commercial_mowers/features_attachment/ztraks_com/480295_mod_deck_oval_275x175.jpg)


Key features of the 7-Iron™ PRO Mulch On Demand mower deck:
- Deck can be converted from a wide-open side discharge mode to a fully chambered mulching mode with a single move of a lever.
- NOTE: Mulch On Demand decks are a balance between a side discharge deck and a side discharge deck with a mulching kit.
- Deck is stamped 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 stamped from a single sheet of steel rather than multiple fabrications. Anti-skid step on the deck provides for easy machine mounting.
- Mulch On Demand decks are superior to aftermarket chute blockers due to the movable baffles.
- Higher blade tip speed than many competitors - 18,500 fpm (5,639 m/min) for more blade cuts per inch mowed.
- Rounded corners of the stamped deck help distribute impact stress to reduce the potential of damage when the mower contacts trees, rocks, curbs, and other fixed obstacles.
- Deep-deck design of 5.5 in. (14 cm) delivers excellent airflow so material can be processed quickly and efficiently.
- Wider and higher discharge opening provides even clipping dispersal for an excellent finished appearance in all conditions.

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.

Mulch Kits


The mulching attachment allows converting the mowers so they can be used to perform the mulching function (grass or leaves) of this system.
The attachment consists of special mulching blades, mulch baffles to direct the clippings into the blade for recutting, and a discharge closure and hardware. The adjustable baffle can be moved to one of five positions to match conditions using the convenient wing nuts.
Operating tips when mulching:
- Mow when the grass is dry.
- Observe the one-third rule.
- No more than one-third of the grass blade should be cut off at one time. This allows more efficient mulching and will promote the continued good health of the grass. If the desired cut height cannot be achieved by cutting off one-third, or there is clumping of the clippings, it may be required to cut higher; wait a day, then lower the mower and make a second pass.
- Mow at proper intervals - approximately every four days to five days.
- Always mow with sharp blades.
