QA7 electric reel drive system meets customer needs for reduced hydraulic leaks, sound levels, and fuel consumption
QA7 electric reel motor
The electric reel design meets the largest customer needs:
- Eliminating 90% of the chances of an unsightly, damaging hydraulic leak by removing 150 leak points from the reel drive circuit
- Fuel Savings of up to 30% on the 7700A E-Cut™ Hybrid, and 21% on the 6700A E-Cut Hybrid, by mowing at reduced throttle minimizes operating costs
- Sound level reduction of up to 3dB(A) when mowing at reduced throttle opens up the operating window by being more friendly to neighbors
56-Volt, 240 amp Smart alternator and electric reel motors provide power for mowing, verticutting, and scalping
Smart Alternator
An innovative 56-volt, 240-amp alternator provides plenty of power for mowing, as well as more rigorous applications of scalping for overseeding and verticutting up to 1/4” (6.35 mm) deep.
- Belt driven from the engine, meaning no additional batteries required and less maintenance
- Integrates with LoadMatch™ by sensing load on the mowing system, and slowing traction speed to maintain cut quality when heavy loads are encountered
To handle the toughest loads that often come with Quick-Adjust 7 (QA7) applications, the reel motors have been updated compared to the QA7 design. The QA7 motors feature longer cooling fins for optimal cooling, and a larger internal bearing design.

TechControl display maximizes performance and uptime by allowing more control in operation and diagnostics
TechControl display
Password-protected settings
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.
Mow setting screen
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.
Turn-speed setting screen
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)
Input/output screen
Service timers screen
The A-model PrecisionCut™ Mowers, E-Cut™ Hybrid Mowers, and TerrainCut™ Mowers have the latest in advanced diagnostics through the TechControl display. Most all diagnostics are performed while sitting in the operator’s seat.
The TechControl has onboard visual diagnostics allowing quick and easy machine diagnostics, maximizing up time. The system allows technician to see inputs and outputs of the electrical system. Also, the technician can see stored controller codes on the machine to aide in troubleshooting incidents that may have occurred while on the course.
The TechControl will also display the notification for maintenance of the hydraulic and engine oils using service timers to notify when it has reached the time to perform the required service.
Language settings
Choose from a list of several languages to use for the TechControl.
Operator warning notifications are incorporated into the TechControl and will alert the operator if a problem arises during operation.

AutoPedal™ feature lowers sound levels and fuel consumption during transport
AutoPedal
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.
eHydro™ hydrostatic pump and large-capacity wheel motors for serious hill-climbing capabilities
Large wheel motors
eHydro™
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.
Forward/reverse pedals
The operator will like the eHydro, too. The pedal effort has been reduced, thus reducing the foot fatigue during many hours of mowing.
LoadMatch™ electronic setting compensates speed of machine to keep power to the cutting units to maintain cut quality
LoadMatch setting
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.
LoadMatch puts the manager in control of cut quality instead of the operator.
