The Gator™ HPX Utility Vehicle has a precision-engineered drivetrain system to better utilize engine power and to improve acceleration, hauling, towing, and hill-climbing capabilities. Power is transmitted from the engine through a continuously variable clutch system to the transaxle. Key elements of the drive system include:

• Transaxle with high and low ranges, neutral, reverse, and park
• Engine
• Variable-speed drive

Variable-speed drive

The variable-speed drive consists of two clutches and a drive belt:

• Drive clutch is attached to and rotated by the engine.
• Driven clutch is attached to and drives the transaxle.

How variable-speed drive works:

1. As the engine speed increases, the spring-loaded drive clutch is closed by weights being forced out by centrifugal force.
2. As the drive clutch closes, the belt rides up to the largest diameter of the drive clutch and forces open the driven clutch.
3. With the belt running in the smallest diameter of the driven clutch, the speed being transferred to the transaxle is increased.
4. The driven clutch is designed to sense varying loads (inclines, mud, etc.) and constantly adjusts drive speed upward or downward so that engine rpm remains constant at constant throttle position.
5. Start in gear, neutral, or park position for quick starting. The service brake must be engaged to start when in gear or neutral.
6. To shift out of park, the service brake must be pressed to release the parking solenoid. An audible click will be heard and then the vehicle can shift out of park into the desired gear.

Transaxle and mechanical front-wheel drive (MFWD)

• Two-speed, fully enclosed, oil bath transaxle allows superior pulling ability
  • Low range is 0 km/h to 19 km/h (0 mph to 12 mph)
  • High range is 0 km/h to 40 km/h (0 mph to 25 mph)
• MFWD and rear transaxle are protected by skid plates
• Helical forward and reverse gears are used for quiet operation
• Selectable four-wheel drive (4WD) system with a limited slip front differential and dash-mounted electronic rocker switch
  • Provides exceptional traction in challenging conditions
  • More control descending hills with 4WD engaged – all four wheels help slow the vehicle down, and clutch engagement is still necessary to prevent free-coasting
  • Near instantaneous torque to the front wheels once electronic switch is engaged
  • Maintains turf-friendly operation in two-wheel drive (2WD mode)
  • Combined with rear traction assist - (differential lock) can provide excellent traction in challenging conditions

Location and status

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

• Location history-Display of map with current and past locations of each vehicle.
• Speed-Maps each vehicle’s current speed, so you can target operator training.
• Hours of operation-Reports the time of day the vehicle has been operated.
• Geofencing-Alerts when a vehicle enters or exits a prescribed area, for example if the vehicle has been stolen or an operator entered a prohibited area.
• Curfews-Alerts if the vehicle is operating outside prescribed times.

Engine hours

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

• Sync-The vehicle 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

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

Machine Analyzer Tool

On select products, the modem reports the hours the vehicle spent working and idling. 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 vehicle’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.
