Commercial-quality deck design

A large volume of material can be thoroughly processed with the deep-deck design:

Unique baffling system is designed to reduce clumping and windrowing often associated with rear-discharge mowers.
- Efficiency is enhanced with baffles surrounding each blade to control material as it is moved to the rear.
- Material exits the deck quickly as the baffles are lower at the rear.
- Movement of material is controlled to minimize the likelihood that clippings are thrown onto unwanted areas.
Less debris gets on the operator as material is directed to the rear and toward the ground.
- Debris is kept low and directed into the turf by the flexible rear shield.

Level cut

Center deck rollers and left wheel

Right-rear deck wheel

The deck is suspended from and supported by the machine to provide a level cut. Mower deck wheels and rollers help smooth out the mowing job in uneven conditions and reduce the chance of scalping the lawn:

Two wide front rollers at the center of the mower support the deck when necessary to prevent scalping.
Wheels at all four corners protect the deck from scalping at the sides of the mower.
Continued effectiveness results from wheels and rollers that are double captured for extra strength, which reduces the chance of damage.
Height of rollers and wheels is adjustable to suit mowing conditions.
- Higher setting (shown in images) are used when mowing at lower cut heights and for rougher conditions at all cut heights where you want to reduce the chance of the wheels hitting the ground.
- Lower settings are used for higher cut heights and for helping to smooth out the mowing job.
Mower cut height is adjustable from 1 to 5.5 in. (2.54 to 14 cm) in 0.25-in. (0.64-cm) increments from the machine operator’s station.

Michelin® X® Tweel® Turf airless radial tire technology option for a smoother ride and more uptime

Michelin X Tweel Turf on Z997R

Flat-free rear tire on ZTrak™ Mower

John Deere leads the commercial zero-turn mower industry with use of the Michelin X Tweel Turf technology.

Michelin is a world leader in tire manufacturing and technology. This airless radial tire solution is an industry first for John Deere, which provides a smoother ride for the operator and additional advantages to John Deere owners.

Advantages of the Michelin X Tweel Turf include:

Mowing performance is improved.

Unique energy transfer within the poly-resin spokes reduces the bounce associated with pneumatic tires, to give a smoother ride.
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, to give a smoother ride.
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.

Michelin X Tweel Turf

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 easily bolts onto any Z997R ZTrak Mower.
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.

Tires deliver exceptional traction, maneuverability, and reliability
