2026 John Deere Golf & Sports Turf Aercore 800 

• 31.5-in. (80-cm) coring
• Lightweight design
• Drive tire core deflectors

Features May Include: 

Coring head located between the drive tires for maximum contour-following capabilities without any additional linkages

The Aercore™ 800 is designed around simplicity, and that definitely applies to the ground-following system. In fact, it doesn't need a ground-following system at all.

If the coring head on any aerator were located anywhere other than precisely between the rear tires, a complex linkage system would be required in order to allow the coring head to float and follow undulations.

Take a tractor-mounted aerator for example. The aerator is located behind the rear tires. A float system is required to allow the aerator to follow the contours. As the tractor crests a hill, the natural tendency is to lift the aerator out of the ground. However, the three-point linkage and hydraulic floating system allows the aerator to follow the contours.

No such system is required on the Aercore 800. By locating the coring head precisely between the tires, the tining action perfectly follows the ground that is in contact with the rear tires. No complex linkages are required to enable the coring head to follow the contour. This also promotes consistency of hole depth across undulations.

Narrow, 80-cm (31.5-in.) coring width promotes consistent hole depth on undulating greens

Do you mow your greens with a 56-cm (22-in.) cutting unit, or do you mow them
with a 76-cm (30-in.) cutting unit? Most will agree that greens are mowed with 56-cm (22-in.) cutting units, or maybe even 45.7-cm (18-in.) cutting units. The 76 cm (30-in) cutting units are not acceptable for mowing greens.

Why do you mow greens with a narrower-width cutting unit? The answer is to eliminate opportunities for scalping, improving overall turf health and providing excellent cut quality. The narrower the cutting unit, the less risk there is of scalping the turf in an undulation.

The same principle applies during aeration. During aerification, you are looking to impact the top 3 in. to 4 in. (7.6 cm to 10.2 cm) of the soil profile. A narrow aerator is going to follow undulations much better than a wider one, keeping a more consistent depth throughout the aeration practice. A consistent depth means more compaction relief at the full depth of aeration and even more accurate topdressing applications.

Look at the diagram above as an example. The picture to the left increases the width by 50 percent to 48 in. (123 cm), while the picture to the right shows the Aercore™ 800. Both are aerating on the exact same slope.  As is shown, the wider aerator punches much shallower as you get to each end of the aerator.

Take particular note of the last two to three tines on each end of the 48-in. (123-cm) aerator that are significantly shallower than the outer tines on the Aercore 800. This means the top 3 in. to 4 in. (7.6 cm to 10.2 cm) you are trying to impact as part of the aeration process is now much less than that as you get farther from the aerator's center. 

When calculating topdressing, this is significant. Now the calculation you have run at 3 in. to 4 in. (7.6 cm to 10.2 cm) of depth, based on square footage aerated, means you will have purchased excess topdressing, and more importantly, you will not have impacted as much of the soil profile as anticipated.

This diagram proves the John Deere Aercore 800 does a much better job of keeping depth consistent across the entire undulation. Just like a greens mower, a narrow walk-behind aerator provides greater consistency on undulating terrain in comparison to wider machines.

Industry-exclusive verticutter attachment gives the Aercore™ 800 more versatility than any other walk-behind aerator in the industry

The verticutter attachment may be fitted to any Aercore 800 machine equipped with the 25-hp Kohler® Command Series engine.

The verticutter utilizes carbide-tipped blades and may be operated to a maximum depth of 1-3/4 in. (44.5 mm) in any of the Aercore 800’s four operating gears. Soil conditions will determine whether or not maximum depth can be achieved. A 31.5-in. (80-cm) width matches the aeration width of the Aercore 800. The standard blade spacing from the factory is 1 in. (25.4 mm), but it can be increased or decreased using spacers in increments of 1/4 in. (6.4 mm).

Featuring a precise, no-tool depth adjustment, the verticutter attachment allows superintendents to operate at virtually any depth up to 1-3/4 in. (44.5 mm). A convenient handle and transport bracket allows the operator to lift the verticutter to a higher position for transporting.

The verticutter utilizes a belt drive system that engages when the coring head is lowered and disengages when the coring head is raised. By utilizing the same electrohydraulic lift/lower system currently on the Aercore 800, an operator may raise the verticutter without the engine running.

Standard tire scrapers for the verticutter eliminate any debris buildup to maintain a consistent verticutting depth.

Once installed, the versatility of the verticutter attachment allows the operator to aerate only, verticut only, or simultaneously aerate and verticut. To aerate only requires simply disengaging the verticutter belt drive, located underneath the belt drive cover. Superintendents choosing to verticut only may do so by simply disengaging the two coring head belts and securing them with the provided belt latches.

Powerful 25-hp*(18.6-kW) gas engine provides plenty of power for aerating and verticutting simultaneously

The Aercore™ 800 utilizes a 25-hp (18.6-kW) gas engine. Why this much power with a 31.5-in. (80-cm) walk-behind aerator? There are two primary benefits.

The first benefit is the increased horsepower allows the engine to turn at a much-slower rpm on entry and exit when the throttle-back solenoid is turned on. The throttle-back solenoid slows the engine down on both entry and exit to eliminate tufting of the turf as the coring head lifts and lowers. 

Turning the engine as slowly as possible without stalling is key. The increased power provides sufficient power to the coring head at a reduced rpm to further improve entry and exit hole quality. This reduced rpm is preset from the factory and, in most cases, should not need further adjustment.

The second benefit is the Aercore 800 offers an optional verticutter attachment to provide an industry-exclusive aerating and verticutting combination. This tandem offers a productive and versatile option that no other competitor can do.

The 25-hp (18.6-kW) engine allows the verticutter alone to operate at a depth of up to 1.75 in. (4.4 cm). Also, the increased horsepower allows the aerator and verticutter to be run simultaneously to impact even more surface area and further reduce compaction as part of the aeration process. Course conditions will dictate how deep the verticutter can be run in combination with a maximum aeration depth.
