Location and status

Operations Center map displaying past locations of a mower

Mobile view of Operations Center map showing GPS speed

The JDLink M Modem regularly transmits the location and operational status of each mower in the fleet so you can monitor mowing progress in Operations Center.

Location history-Display of map with current and past locations of each mower.
GPS Speed-Maps each mower’s current speed, based on GPS location data, so you can target operator training.
Hours of operation-Reports the time of day the vehicle has been operated.
Geofencing-Alerts when a mower enters or exits a prescribed area, for example if the mower has been stolen or an operator entered an area that should not be mowed.
Curfews-Alerts if the mower is operating outside prescribed times, for example residential areas with early-morning noise restrictions.

Engine hours

The modem regularly transmits the mower’s engine hours to inform maintenance planning and balance use.

Sync-The mower reports actual engine hours to the Operations Center.
Key-Engine hours are estimated by monitoring the key switch. Engine hours can be corrected in Operations Center.

Maintenance planner

Operations Center Maintenance Planner

Factory or custom maintenance plans can be established in Operations Center. Maintenance alerts are sent when engine hours reach maintenance intervals.

Machine Analyzer Tool

Operations Center Machine Analyzer Tool

On select products, the modem reports the time the mower spent transporting, idling, and working. The Operations Center’s Machine Analyzer tool reports usage data which allows you to analyze operator behavior, identify causes of low productivity, and initiate corrective actions.

Fuel level

On select products, the modem reports the fuel level. On these products, an analysis of fuel consumption is available in the Operations Center Machine Analyzer Tool. Measuring fuel consumption enables you to address causes of excessive fuel use.

Diagnostic trouble codes (DTCs)

On select products, the modem transmits the trouble codes generated by the mower’s control units to the Operations Center. Addressing DTCs can reduce downtime and repair costs. For example, a low-engine oil pressure DTC can indicate an engine is low on oil. Addressing the issue can prevent costly downtime and repairs.

To help address issues quickly, when a DTC is generated, the Operations Center can display a push notification on the mobile app and send an email. Operations Center can also be configured to limit notifications to stop-level severity DTCs.

Service Advisor Remote

On select products, John Deere dealers can perform remote diagnostics, software programming, and adjustments without the cost of a service call.

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

Michelin X Tweel Turf on Z997M

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 Z997M and 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

Run flat front caster wheel

Pneumatic rear drive wheel

The Z997M and Z997R ZTrak Mowers are equipped with 15x6-6 flat free front caster tires that provide:

Excellent reliability and uptime
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 reduce between-blade striping

A choice of rear wheel options is available for factory installation:

26x12-12 4 PR, square shoulder, pneumatic drive tires in base equipment for excellent traction, flotation, and curb climbing
