The mower deck shell is forged from a single sheet of 7-gauge, 0.179-in. (4.6-mm) steel. There are fewer welds to wear or break than shells built from multiple fabrications.
Rectangular leading-edge reinforcement and rounded corners help distribute impact stress to reduce potential for damage when the mower contacts trees, rocks, curbs, and other fixed obstacles.
The trim edge of the deck is equipped with a bumper that provides extra abrasion resistance to protect the machine and the property.
Three 1-in. (2.5-cm) cold-forged spindle shafts are heat-treated for strength and supported by ball bearings. Deep spindle pockets keep the blades aligned, even after years of tough operation. The ribbed spindle housings are made of aluminum and have an 8-in. (20-cm) base for added strength and heat dissipation.
Minimal welds provide a smoother underside with fewer sharp corners for reduced material buildup.
Higher blade-tip speed than many competitors - approximately 18,000 fpm (5,486 m/min) for more blade cuts per inch mowed.
A deep-deck design of 5.5 in. (14 cm) delivers excellent airflow so material can be processed quickly and efficiently.
The front edge is raised above the blade plane to allow even cutting of tall grass.
The wider and higher discharge opening provides even clipping dispersal for an excellent finished appearance in all conditions.
Blade overlap is 1.6 in. (40.6 mm) to reduce striping between blades.
Dual-captured front-corner, front-center, and rear-center anti-scalp wheels provide deck flotation over even the toughest terrain.
A folding engine guard provides access to the mower deck drives for cleaning and maintenance.
Spindle covers allow for cleaning while installed and can be removed without tools for maintenance. Spindle grease fittings are accessible through the top of the spindle cover.
Adjustment screws at each lift point are used to level the mower deck side-to-side and set the rake angle. The mower deck is fully supported throughout the leveling process, enabling predictable adjustments and precise height measurements.
M and R Series QuikTrak© Mowers have a spacious operator platform designed to keep operators comfortable and improve stability, while providing storage.
Moving is essential for operator ergonomics, so the M and R Series QuikTrak Mowers are equipped with a 24-in. (61-cm) wide foot platform that gives the operator room to vary their stance. The fender-mounted foot holds on R Series Mowers enable an even wider range of stance options.
The platform is spring loaded to keep bumps from jarring the operator. Large tires help isolate the operator from rough ground as well. R Series Mowers include a rubber mat on the foot platform.
The forward pitch of the new M and R Series leaning pad centers the operatorâs core over the vehicles center of rotation. This location has the least centrifugal force, keeping the operator stable and in control. The leaning pad is padded for comfort and bolstered to provide side support to the operator while traversing uneven terrain and during end-of-pass turns. The leaning pad on R Series includes extra bolstering and a color accent.
The wide foot platform gives the operator the freedom to shift their weight from side-to-side on uneven terrain. Similarly, the forward-pitched leaning pad allows the operator to lean forward to increase stability or lean rearward to increase traction.
A versatile mesh storage bin is within the operatorâs reach and can be used for holding refreshments, tools, or trash.
The color coded and logically placed controls on M and R Series QuikTrak Mowers are designed to get new operators up to speed quickly. A display panel assists in operating the mower and alerts operators of problems, to reduce downtime and repair costs. The key, choke (carbureted models only), throttle, and power take-off (PTO) switch are located at the operatorâs fingertips.
Ground speed and direction are easily controlled by moving the two hand-lever hydrostatic drive controls forward or reverse.
Front and rear stationary reference bars stabilize the operatorâs hands, which maintains precise control as the mower changes speed or direction. The bars also reduce fatigue from control lever operation.
Control levers return to neutral automatically, and a positive neutral-lock holds the control levers in neutral when the park brake is engaged.
The M and R Series QuikTrak Mowers are equipped with a display panel that assists in operating the mower, alerts of problems to reduce downtime and repair costs, and provides on-board diagnostics to speed troubleshooting. The display panel includes:
The diagnostics mode provides error codes, system voltage, and circuit continuity tests that can report switch functionality and circuit continuity in seconds without tools.
A park brake is provided for parking the vehicle and for transport. It must be engaged to start the machine and should be engaged whenever the machine is not being used. On M and R Series QuikTrak Mowers, the park brake is built into the transaxles, which reduces the effort required to engage the brake.
An easy-to-use height-of-cut system allows the operator to see and adjust the height-of-cut setting from the operator station.
The E and M Series QuikTrak mowers have a 1200-hour or 36-month, whichever comes first, bumper-to-bumper warranty. The R Series mowers have a 1500-hour or 36-month, whichever comes first, warranty. All QuikTrak Mowers also have an unlimited hour 24-month warranty. The warranty is hassle free, with John Deere covering the complete machine.
The QuikTrak warranties are also aligned with John Deereâs commercial walk-behind and Z900 ZTrak Mowers so you can roll your entire fleet on one contract, with one warranty duration, and one payment schedule.
The M and R Series QuikTrak Mowers are designed to speed maintenance and cleaning so the mower can get back to work.
All service and maintenance points are within easy reach.
Canister-type heavy-duty air cleaner is easy to reach and easy to service:
Engine oil service points are grouped together in an easy-to-reach location:
A removable leaning pad, removeable rear service panel, and folding rear service panel provide access to key components for maintenance and cleaning.
A secure location is provided to protect the battery. Only the leaning pad needs to be removed for access.
Access to check and service the hydrostatic transaxles and drive belts are readily available at the rear of the machine.
Transmission bypass valves are located on the hydrostatic pumps to enable moving the vehicle without the engine running.
A periodic service chart is provided for convenience in keeping up on required service.
Spindle covers allow for cleaning while installed and can be removed without tools for maintenance. Opening the engine guard also provides access to mower deck drives.
Adjustment screws on each lift point are used to level the mower deck side-to-side and set the rake angle. The mower deck is fully supported throughout the leveling process, enabling predictable adjustments and precise height measurements.
Four tie-down locations, two at the front and two at the rear, are provided for safely towing or anchoring the vehicle.
To speed access to owner information web pages, a QR code is printed onto a product identification number (PIN) label located on the rear of the mower, to the right of the leaning pad. The owner information web pages include links to:
From the operator's platform to the mower deck, John Deere QuikTrak© Mowers have a compact and functional design:
Whether mowing hills or on level terrain, trimming or mowing straight-away, the operator of a John Deere QuikTrak is able to affect the performance of the machine with their body:
QuikTrak mowers are frequently used on properties with concrete street curbs. The ability to traverse curbs boosts productivity by reducing transit time. The M and R Series QuikTrak Mowers include the following features that allow for efficient and damage-free curb crossings:
Large tires provide a smoother ride and increased traction:
The M and R Series QuikTrak© Mowers use Tuff Torq TZT13 Integrated Transaxles, the same transaxles used on the Z900 ZTrak© Mowers. The integrated transaxles:
Tuff Torq is a trademark of Kanzaki Kokyukoki Mfg. Co., Ltd.
Key safety features of QuikTrak© Mowers include:
QuikTrak mower decks are evaluated by the manufacturer (John Deere Turf Care) and conform to American National Standards Institute (ANSI) B71.4 2017 safety certification specifications for commercial turf care equipment.
The optional LED strobe light attachment increases visibility of the QuikTrak mowers to motorists. The kit includes two lights providing visibility in all directions.
John Deere leads the commercial zero-turn mower industry with use of the Michelin X Tweel Turf technology for the QuikTrak Mowers:
