2024 John Deere 9009A TerrainCut™

Stamped rotary decks and rigid frame construction to maximize deck durability

The 9009A TerrainCut Rough Mower is equipped with five and the 7400A TerrainCut Trim and Surrounds mower is equipped with three 27-in. (68.6-cm) stamped rotary decks for superior productivity and strength. The rotary decks perform exceptionally well across a wide range of grass types, including warm- and cool-season grasses.

Rear-discharge design provides premium cut quality and dispersal for less clumping and blowing for clean up

The 9009A and 7400A TerrainCut™ Mowers 27-in. (68.6-cm) deck features a deck design with an asymmetric rear discharge cutout and molded chute to promote better airflow, leading to improved clipping dispersal and cut quality.

The unique shape of the deck shell cutout includes a heavily rounded opening on one side that gradually transitions to a larger opening on the other side of the cutout, allowing the grass to exit the deck evenly while significantly reducing the possibility of the deck congestion. This design incorporates deck structure along the bottom of the discharge area that reduces sound power, does not affect cut quality negatively, and acts as a foot guard eliminating the need for an external guard that can lead to external grass build up which can be dropped in the mowing pass over time.

When the asymmetric deck shell discharge shape is used in combination with the asymmetric discharge chute, this deck outperforms the competition in cut quality by minimizing clumping with smooth transitions and guiding the discharge material in a more dispersed pattern.

The improved dispersal will lead to less clean up and blowing, allowing machines to mow earlier in the day while saving time and reducing labor.

The proper blade selection for heights of grass, grass type, and sharp blades are keys to improved cut quality and dispersal. The removal of no more than one third of the grass blade is recommended. During heavy growth times it may require changing blades, mowing more often or raising the height of cut to improve clipping dispersal.

No-tool 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 9009A and 7400A TerrainCut™ Mowers are no different. All HOC adjustments can be performed without tools with an innovative notch system, similar to what is included on the Quick-Adjust 5 and Quick-Adjust 7 reel cutting units.

To adjust the HOC on the 9009A and 7400A TerrainCut, pull the levers at each end of the front and rear rollers outward. With the levers pulled out, give a quick tug to disengage the teeth in the notches. This allows the rollers to rotate upward and downward freely and easily.

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

MORE CONTROL WITH THE TECHCONTROL DISPLAY WITH A LARGE EASY-TO-READ SCREEN

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

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 take performance, traction, and operation to the next level.

The new system was designed to take on the most challenging course conditions. The traction drive pump flow increased 35 percent and the wheel motors increase 17 percent in displacement over prior models. These increases to the traction system makes the A-models ideal for undulating terrain providing superior performance and traction out on the course.

The new 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 is electronic.

Approximately 110 parts have been eliminated from the traction drive system compared to prior models. The new design also eliminated two adjustments. Reducing the complexity of the drive system means no more linkages to adjust or repair, decreased routine maintenance, and providing reliable day-in/day-out operation.

AutoPedal™ feature lowers sound levels and fuel consumption during transport

The AutoPedal feature controls engine rpm and transport speed of the machine through the eHydro™ foot pedal controls. AutoPedal is similar to an automobile gas pedal operation; the more the forward pedal is pressed, the faster the machine moves and the higher the engine rpm; pressing the pedal less, the slower the machine moves and the lower the engine rpm.

On conventional machines, the engine rpm is controlled by the operator by means of a manual or electric/manual throttle. Operators are trained to always operate the engine at wide-open throttle. Running at wide open throttle means running the engine at its fastest speed, which increases the sound levels and fuel usage.

The AutoPedal system allows the engine to only run as fast as needed, meaning that as operators transport around the course, the engine speed is only as fast as needed for the transport speed. If the operator approaches play and stops, the engine rpm goes to idle. This makes transporting quieter and since the engine does not run full speed all the time, it reduces fuel consumption.

Once the operator reaches the mowing site, engages the mow switch on the CommandARM™ controls, the engine rpm automatically increases to full throttle for mowing.

Width on demand—match the conditions with the touch of a button

Featuring both a 68-in. (172.7-cm) and 74-in. (188-cm) width of cut that can be changed with the touch of a button, the 7400A Trim and Surrounds Mower ensures that all grass in its path is cut in both flat and undulating conditions.

The narrower width of cut is recommended for undulating terrain and tight turns where more cutting overlap is required, to make sure that no uncut grass is left behind. This width expands the total cutting unit overlap to maximize cut quality by eliminating uncut strips of grass that may be caused by undulating terrain, or a layout that requires a lot of tight turns.
This exclusive feature provides a productivity boost compared to competitive equipment in the marketplace. The wider width of cut setting is recommended on flat terrain with long straight runs. This width of cut has maximum productivity with minimal overlap.

Reach Trimming System—shift out to trim around bunkers and other hard-to-reach places

Having difficulty trimming around bunkers? The 7400A TerrainCut™ Trim and Surrounds Mower is here to help. Featuring an industry-exclusive Reach Trimming System, the 7400A Mower reaches out to bunkers and trims around them with ease.
With the Reach Trimming System, one of the front decks can be shifted outward to extend the deck 15 in. (38.10 cm) beyond the outer edge of the tire for trimming. Shifting only one deck helps keep the machine's center of gravity more consistent, maintaining the machine's overall stability.

It is recommended to mow the outer areas around the bunker or other areas to be trimmed first, and then use the Reach Trimming System as the last pass against the area to be trimmed.
Operating the Reach Trimming System is done with ease. It is very similar to adjusting the mirrors in a car. To adjust the mirrors, there is a switch to select which mirror to adjust and another switch to adjust the direction the mirror is moved.

GRIP All-Wheel Drive Traction System moves flow from wheels that slip to those that grip

Hill-climbing power is essential with any golf course mower, and this is one area where the A-model PrecisionCut™ and TerrainCut™ Trim and Surrounds Mowers truly excel. A powerful diesel engine supplies power to the system. Combine that with a new larger eHydro™ and wheel motors the GRIP all-wheel drive traction system, and the A-Model is one powerful hill-climbing machine. The new traction drive delivers 35 percent more flow from the hydrostatic pump and 17 percent more wheel torque than previous models to deliver the hill-climbing performance expected with a trim and surrounds mower.

The GRIP system transfers hydraulic flow from wheels that slip to wheels that grip. For example, if the right front wheel starts to slip, hydraulic flow goes to the left front and rear tires to maintain traction power.
The GRIP all-wheel drive traction system is standard equipment with the A-Model Trim and Surrounds Mower. It is also engaged at all times, in mow or in transport.
