• The 8900A features a width of 114 to 130 inches depending on cutting unit size, giving more productivity in terms of acres mowed per hour.
• Another productive advantage of the 8900A is the 8 miles per hour mowing speed.
• Be productive but carry a light footprint: the 8900A comes in significantly lighter than its main competitor.
• Versatility is a hallmark: 8900A has 26″ and 30″ verticutters and large capacity reel motors for scalping during over-seed operations.

Product Features for John Deere 8900A PrecisionCut™ Riding Large-Area Reel Mower: 

TechControl Display:

• Large, easy-to-read screen with passcode-protected settings.
• Allows quick setting or changing of mowing speed, turning speed, and transport speed to ensure consistent performance by different operators.

  Mow Setting Screen:

  • Quickly adjust mow or transport speed for changing conditions.
  • Precise adjustment using a speedometer app on a smartphone or GPS device.

  Turn-Speed Setting Screen:

  • Use TechControl to slow the machine during turns, protecting against turf scuffing.
  • Turn speed control engages when in mow, lifting cutting units for turns, and returns to set mow speed after the turn.
  • Turn speed is a percentage of mow speed, allowing customization (e.g., 50% turn speed reduces maximum turning speed).

  Example:

  • Mow speed = 9.66 km/h (6 mph)
  • Turn speed set at 50%
  • Maximum turning speed = 4.83 km/h (3 mph)

  Input/Output Screen:

  • Advanced diagnostics performed in the operator’s seat.
  • Onboard visual diagnostics for quick machine diagnostics, maximizing uptime.
  • Displays inputs and outputs of the electrical system.
  • Shows stored controller codes for troubleshooting.
  • Displays notifications for maintenance of hydraulic and engine oils using service timers.

  Language Settings:

  • Choose from a list of languages for the TechControl.

  Operator Warning Notifications:

  • Incorporated into the TechControl to alert the operator of problems during operation.

eHydro™ Hydrostatic Pump and Large-Capacity Wheel Motors:

• Utilized in the 9009A TerrainCut and the 8900A PrecisionCut.
• Takes performance, traction, and operation to the next level.
• GRIP system reduces wheel slip, ideal for undulating terrain.
• Electronically controlled hydrostatic pump eliminates mechanical linkages, reducing complexity, and ensuring reliable operation.

Forward/Reverse Pedals:

• Reduced pedal effort for operator comfort during extended mowing.

GRIP All-Wheel Drive Traction System:

• Provides superior traction with hydraulic four-wheel drive (4WD).
• Reduces wheel slip by transferring flow from slipping wheels to gripping wheels.
• Always engaged when driving forward, simplifying the electrical system.
• Disengages in reverse to minimize wheel slip and turf scuffing.

Double-Acting, Single-Rod Hydraulic Steering Cylinder:

• Utilizes the same steering cylinder style as the 2550 PrecisionCut and 2550 E-Cut Hybrid Riding Greens Mowers.
• Delivers straight lines for a professional after-cut appearance.
• Equalizes volume and pressure for easy turns in both directions.

Low Machine Weight and Proper Weight Distribution:

• The 8900A PrecisionCut™ Large-Area Reel Mower is lightweight, reducing compaction and turf stress.
• Features 26.5 x 12-12 turf tires for low footprint and maximum traction.
• Strong traction with low ground compaction.

Easily Accessible Daily Service Points:

• Designed for quick and efficient daily maintenance.
• Hood raises for easy access to engine-oil level, coolant level, hydraulic fluid level, and air-restriction indicator.
• Radiator screen and tilt-out oil cooler for straightforward cleaning.

LoadMatch™ Electronic Setting:

• Compensates traction speed to maintain power to cutting units for consistent cut quality.
• Gives managers control over cut quality in various mowing conditions.

AutoPedal™ Feature:

• Controls engine rpm and transport speed through eHydro™ foot pedal controls.
• Reduces sound levels and fuel consumption during transport.
• Quieter transport with lower fuel consumption, as the engine only runs as fast as needed.
• Full throttle automatically engages when mowing.

Optional Vertical Cutting Units:

• QA7 verticutters for the 8900A PrecisionCut™ Large-Area Reel Mower and the 7200A and 2653B PrecisionCut Trim and Surrounds Mowers.
• Quick adjustments and durable verticutter blades for aggressive maintenance.
• Depth system with Speed Link™ for easy adjustments and paralleling the roller to verticutter blades.
• Integrated Speed Link system for simultaneous adjustments on both ends of the rear roller.
• Efficient depth adjustment using electric drill or pneumatic tool, saving time and money.
• Maximum depth for verticutters is 0.13-in. (3.2 mm).
• Speed reduction during verticutting based on blade depth and turf conditions, with a maximum recommended travel speed of 3 mph (4.83 km/h).

Note: Electric or pneumatic impact tools cannot be used with the Speed Link depth system.
