2025 John Deere Golf & Sports Turf 8800A TerrainCut 

• TechControl™ Display locks in performance, and uptime
• LoadMatch™ to maintain cut quality
• 27% more hp, 20 percent more torque in the mowing circuit
• Final Tier 4 without sacrificing horsepower

Features May Include: 

• Rotary decks feature rigid construction, rear discharge, double bearings, and high torque motors in one tough package

The 8800A TerrainCut™ Rough Mower is equipped with five 53.3-cm (21-in.) rotary decks for superior contour-following ability and cut quality, minimizing scalping opportunities in desirable golf course roughs.

The rotary decks perform exceptionally well across a wide range of grass types, including warm- and cool-season grasses.

A strong, 10-gauge shell construction is an integral part of this durable deck. Surrounding the deck is a tough, cast-steel frame designed to protect the deck shell.  It all starts with the frame on top of the deck. The shell is bolted to the frame, providing extra protection.
 
The front and rear roller brackets are attached to the framework, so as the front and rear rollers encounter obstacles, the force is transferred through the frame rather than through the deck shell. In addition, an angled skid plate between the front roller and deck shell helps protect the front lip of the deck in tough terrain.

Roller brackets are cast steel with extended housings to effectively protect the roller bearings from a wide range of debris types.

The decks are rear discharge to allow for easy trimming using either the left-front or right-front deck. An optional mulch kit is available for those who desire to mulch clippings.

The new double yoke design also has new bushings with greater contact area to improve wear characteristics. This, along with an increase of approximately 25 percent in contouring for the front decks over prior models, makes the new double yoke ready for the challenges of any course.

The combination of a new larger deck circuit pump and high-torque deck motors on the 8800A TerrainCut provide a consistent and clean quality of cut across a wide range of operating conditions with 20 percent more torque over prior models. This mowing circuit has no problem standing up the grass to provide an outstanding cut quality and promoting optimal clipping dispersal with the rear-discharge system.

• TechControl display maximizes performance and uptime by allowing more control in operation and diagnostics

Passcode-protected TechControl display enables quickly setting or changing mowing speed, turning speed, or transport speed to limit variations in performance by different operators.

Quickly adjust the mow or transport speed to make sure mow speed is what is needed for the changing conditions. The setting can be adjusted precisely using a speedometer app on a smartphone or global positioning system (GPS) device.

Use the TechControl to slow the machine during turns while mowing and protect against turf scuffing and aggressive turning operators.

The turn speed control engages when in mow and the cutting units are lifted for turns. Once the turn is made and the cutting units are lowered, the machine speed returns to the set mow speed.

The turn speed is a percentage of mow speed. When set to 100 percent, turn speed control is off or allows 100 percent of the mow speed in turns. Turn speed setting of 50 percent allows only 50 percent of the set mow speed to be reached during turns.

Here is an example:

Mow speed = 9.66 km/h (6 mph)
Turn speed set at 50 percent
Maximum turning speed will be 4.83 km/h (3 mph)

• eHydro™ hydrostatic pump and large-capacity wheel motors for serious hill-climbing capabilities

The eHydro™ traction pump and wheel motors in the new A-model takes performance, traction, and operation to the next level.

We designed the new system to take on the most challenging course conditions. These improvements to the traction system makes the A-models ideal for undulating terrain providing superior performance and traction out on the course.

The traction system in the A-models is driven by a servo-controlled hydrostatic pump. The control of the pump is no longer mechanical linkages but instead it is electronic.

In total approximately 94 parts have been eliminated from the traction drive system along with 4 adjustments compared to prior models. The design reduced the complexity of the drive system meaning no more linkages to adjust or repair decreased routine maintenance and providing reliable day-in/day-out operation.

• Tooled notch adjustment system makes height-of-cut (HOC) changes a breeze

One common element among John Deere golf mowing products, reel or rotary, is that adjustments are quick and easy. The 74000A, 8800A, and 9009A TerrainCut™ Rough, Trim, and Surrounds Mowers are no different. All HOC adjustments can be performed with simple tools utilizing an innovative notch system.

Height of cut changes on rotary decks are infrequent adjustments, and customer feedback has been that they prefer a system that utilizes tools with more positive clamp load to stay engaged and keep height of cut consistent in tough conditions.  With the tooled design, there are no hand-engaged latches that may loosen over time.  Instead, a bolt and nut are used to more positively clamp the adjustment in place.  The deck still utilizes the notch system with a pointer and numbered indicators for the height of cut.

To adjust the deck, (2) 15 mm wrenches or sockets will be required, one to loosen the nut on the inside of the adjuster and the second to hold the bolt head.  The system only needs to be loosened enough to disengage the teeth from the notches, but does not need to be completely removed to perform the adjustments. This allows the rollers to rotate upward and downward freely and easily.

Locate the HOC indicator on the inside of the adjuster arm and line up the tabs or use the top edge of the adjuster arm to line up the height on the gauge located on the outside. Re-engage the notches and re-tighten.

The adjustments must be performed on both the front and rear roller, and both rollers have the same adjustment process. A HOC label is also located on the rear of the deck to serve as a guide for setting the height of cut.

The HOC is adjustable 1.9 cm (3/4 in.) to 10.2 cm (4 in.), in 0.64-cm (1/4-in.) increments.
