John Deere HPX815E Work Series Utility Vehicle

Precision-engineered drivetrain system

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

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)

Transaxle and 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

• The OPS performance is certified to Society of Automotive Engineers (SAE) J219 standards.
• Glass doors can be dealer installed to complete the cab enclosure.

OSR

• Certified to American National Standards Institute (ANSI) B71.9 standards

Nets are standard equipment on the Gator HPX.  Features of the nets include:

• One-handed operation

• Great visibility

Deluxe cargo box

Extra-durable deluxe cargo box ensures hard-working performance and longevity

The deluxe cargo box consists of a 15 percent glass-filled polypropylene composite material that eliminates rust and dents and reduces noise.

Deluxe cargo box tailgate

Tailgate handle

Tailgate lowered to 150 degrees

The tailgate can be opened or removed for easier cleanout and to carry longer items. The tailgate has been improved, features truck-like performance, and can be operated with one hand.

The standard-installed lanyards can also be removed to lower the tailgate 150 degrees for convenient loading and unloading tasks.

Deluxe cargo box tilt

Integrated handle for manual cargo box tilt

The deluxe cargo box is easier to latch, unlatch, raise, and lower with the integrated handle design and gas assist. A prop rod is provided to hold the box in the upright position for operator convenience, as well as limit box pivot travel.

Integrated tie-down points

Additional tie-down points (TH 6X4 shown)

The deluxe cargo box offers integrated tie-down points for increased versatility. Tie-down points are located in the following areas:

• Four corners inside the cargo box bed
• Four points on the load guard directly behind the operator station (A)
• Tie-down bars on either side of the cargo box (B)
• Six points on the underside of the cargo box frame (circled)

Converting deluxe cargo box to a flat bed
