Illustration of Kanzaki dual-unitized hydraulic pump
The hydrostatic drive features a Kanzaki® DUP 17SB dual-unitized hydraulic pump. This dual pump, in a single housing, provides longer life and less maintenance than competitive units.
The pump features a shaft-driven fan for added cooling and longer component life. The swash-plate bearings are roller-type versus ball-type bearings for a longer overall pump life.
Illustration of transmission layout
The transmission module integrates the dual pumps and steering valves in one single housing. The pump is shaft-driven from the engine. An isolator ensures reduced vibration between the engine and the transmission module.
Two wheel motors are installed on the chassis to directly transfer power to both wheels. Commercial-grade, heavy-duty TG0310 310-cc (18.9-cu in.) wheel motors from Parker Ross, part of the Hydraulic Pump & Motor Division of Parker Hannifin®, are also important components of the overall drive system efficiency.
Rigid hydraulic lines are installed between the hydraulic module and wheel motors for long life.

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.
The modem regularly transmits the mower’s engine hours to inform maintenance planning and balance use.
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.
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.
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.
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.
On select products, John Deere dealers can perform remote diagnostics, software programming, and adjustments without the cost of a service call.
A JDLink M Modem is standard equipment on model year 2024 and newer (SN 110,001-) TerrainCut Front Mowers and model year 2024 and newer (SN 690,001-) TerrainCut Wide-Area Mowers.
A JDLink M Modem can be field installed on the commercial mowing products listed below. Field installation attachments simplify modem installation, and include brackets, mounting hardware, harness, and instructions. Field installation requires a JDLink M Modem to be ordered separately. The field installation attachments include a wiring harness therefore the modem should be ordered with the less harness option code.
