GRIP All-Wheel Drive Traction System provides superior traction by reducing wheel slip

For superior traction with a true hydraulic four-wheel drive (4WD), the GRIP All-Wheel Drive Traction System is optional equipment for the PrecisionCut™ and E-Cut™ Hybrid fairway mowers. This system reduces wheel slip by sending flow from the front wheel to the opposite rear wheel.
For example, if the front right wheel starts to slip, hydraulic flow is diverted to the left rear wheel to maintain positive traction. By allowing the flow to cross over to the opposite rear wheel, the system maintains traction not only while climbing straight up hills, but also on side hills, as well. 
The GRIP All-Wheel Drive Traction System is always engaged when driving forward with the PrecisionCut and E-Cut Hybrid fairway mowers. There are no electronics to engage the 4WD system, simplifying the electrical system and the design of the valve at the rear of the machine.
In reverse, a standard switch is provided that disengages 4WD. The switch senses that the reverse pedal has been depressed and shuts off flow to the rear drive wheels. This ensures that the front drive tires are doing the work in reverse rather than the rear tires, minimizing wheel slip and scuffing of turf when backing up an incline.

Tires sized for proper weight distribution and a low ground pressure

When considering a fairway mower's effects on turf compaction, there is more to it than just weight alone. Weight is only a small factor in determining turf compaction.
A key component is the selection of tires used on the machine involves both sizing and tread patterns. The John Deere PrecisionCut™ and E-Cut™ Hybrid Fairway Mowers use large, 26x14-12 front tires for proper front weight distribution, and 20x10-8 tires in the rear to distribute the rear weight.
Both tires use a turf tread to maximize turf friendliness.
They excel in weight distribution providing low ground pressure onto the turf. This provides less tracking, less marking, and less compaction.

Quick-Adjust 7 cutting units have Rotate for Service (RFS) feature allowing access to bedknife

The 6700A, 7700A, and 8700A PrecisionCut™ Fairway Mowers allow all five cutting units to rotate to a vertical position while on the machine, gaining access to the bedknife for quick in-field service. The Rotate for Service feature is an exclusive feature of the 6700A, 7700A, and 8700A PrecisionCut Fairway Mowers.

It is simple and easy to use RFS. Simply use one hand to pull up on the cutting unit yoke to remove weight from the RFS spring; use the other hand to push the spring lever down on the front cutting units. Then use the hydraulic lift system on the machine to pick the cutting units up, and they will move into the vertical position. Lower the cutting units to the ground; the bedknife will be completely accessible without having to remove cutting units from the traction unit or have access to a machine lift.

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.

LoadMatch™ electronic setting compensates speed of machine to keep power to the cutting units to maintain cut quality

LoadMatch is an electronic setting through the TechControl display that allows managers more control of the machine and how it is operated when out on the course.

Most operators will mow as fast as the mow setting will allow, keeping their traction pedal all the way down. However, in some conditions this can lead to poor cut quality.

One example is getting behind in mowing due to weather conditions. The grass is long and lush and to properly cut that amount of grass at one time, the operator should slow the traction speed. This allows the cutting units to maintain proper turning speed, process the grass, and properly cut in one pass. Not slowing down causes missed grass and an uneven appearance. This affects the after-cut appearance and also reduces productivity by having to mow a second time to properly cut the lush grass.

The LoadMatch feature compensates the traction speed of machine to keep power to the cutting units. In the long, lush conditions described above with LoadMatch engaged, the operator would still have the traction pedal all the way down, but the machine would sense the load and slow the traction speed to properly cut the mowing pass. Once the load is reduced, the machine will return to the normal mow speed.

eHydro™ hydrostatic pump for premium ease of use

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 four adjustments compared to prior models. The design reduced the complexity of the drive system, which means no more linkages to adjust or repair, decreased routine maintenance, and more reliable day-in/day-out operation.

Double-acting, single-rod hydraulic steering cylinder for lines as straight as a greens mower

For superintendents who want stripes as straight as they are on the greens, the A-model PrecisionCut™ Mowers and E-Cut™ Hybrid Mowers do exactly that. Utilizing the same style steering cylinder as on the 2550 PrecisionCut and 2550 E-Cut Hybrid Riding Greens Mowers, the PrecisionCut and E-Cut Hybrid Mowers can mow the straightest lines of any mower in the industry today.

Traditional hydraulic cylinders have a rod on only one side of the cylinder. The cylinder on the A-models has one rod that goes through both sides of the cylinder. This equalizes volume and pressure on both sides of the cylinder packing, helping the operator make   perfectly straight lines with little effort.

This system also equalizes the steering effort, meaning easy turns whether turning to the right or to the left.

Easily accessible daily service points mean less maintenance time and more time working

Easier daily maintenance points are designed into the machine to assist operators with complete daily maintenance and to keep the machine running at peak performance, saving valuable time and money.

For ease of service, all daily engine checks are easily accessible by raising the hood. These service points include an engine-oil level check, a coolant level check, hydraulic fluid level, and an air-restriction indicator.

The A-model PrecisionCut™ Mowers, E-Cut™ Hybrid Mowers, and TerrainCut™ Mowers feature a radiator screen that is easily removed without tools and a tilt-out oil cooler for easy cleaning.

Cutting units are stable for easy transporting

The 6080A PrecisionCut™ and 6080A and 8000A E-Cut™ Hybrid Fairway Mowers have cutting units that contact up stops for transport. These up stops are rubber and limit cutting units from swinging during transport to protect the cutting units when transporting down cart paths or bumpy terrain.
