Worthington tanks are manufactured by Worthington Industries, Inc.
All service components are easy to access:
Canister-type heavy-duty air cleaner is easy to reach and easy to service:
Engine oil service points are grouped together in easy-to-reach locations:
Simply raising the leaning pad exposes the hydrostatic oil reservoir, control linkage and other service areas.
A periodic service chart is provided on the back of the leaning pad for convenience in keeping up on required service.
Four tow holes, two at the front and two at the rear, are provided for safely towing or anchoring the vehicle.
One large knob is used to remove service access shields on the mower deck, battery box, etc.:
Threaded ball and socket rod ends are used throughout the QuikTraks:
Access to check and service the hydrostatic pumps and motors is readily available at the rear of the machine.
Transmission tow valves are located on the hydrostatic pumps to enable moving the vehicle without the engine running.
Secure battery box is provided to protect the battery, for reliable operation:
A commercial-quality 23.5-hp* (17.5-kW) at 3600 rpm air-cooled engine powers the QuikTrak™ Mower:
*The engine horsepower and torque information are provided by the engine manufacturer
to be used for comparison purposes only. Actual operating horsepower and torque will be less.
Refer to the engine manufacturer’s Web site for additional information.
Engine is equipped with a replaceable oil filter for longer engine life.
Engine oil fill/check tube, oil filter, and oil drain are located close together for easy and convenient service.
Controls are color coded and logically placed to make them easy for the operator to find and use:
Separate choke is easy to locate and use.
A tire brake is provided to give stability for parking the vehicle on hillsides and for transport; it should be engaged whenever the machine is not being used:
On the 648R, 652R, 652R EFI, 661R, and 661R EFI QuikTraks, an easy-to-use cutting height adjustment system allows the operator to adjust the mower deck cutting height with no tools and minimal effort:
NOTE: Additional information on mower cutting height adjustment can be found in the mower deck section.
QuikTrak™ Mowers use a heavy-duty hydrostatic pump and wheel-motor drive system that gives reliable and consistent performance and long life:
Two Hydro-Gear™ 0.73 cu in. (12-cc) axial piston, variable displacement pumps provide hydraulic power to the wheel motors:
Two individual 15-cu in. (245.8-cc) piston wheel motors power the QuikTrak drive wheels. Their heavy-duty construction and super-efficient axial-piston design provides superior performance and seamless power to the wheels:
A spin-on type replaceable hydraulic oil filter is conveniently located:
A hydraulic fluid oil reservoir is located behind the leaning pad:
Transmission tow valves are provided on each hydrostatic pump to permit moving the QuikTrak without the engine running.
Hydro-Gear is a U.S.-registered trademark of Hydro-Gear Company.
A well-designed mower deck can make the difference between just getting the job done and getting eye-catching results. The 7-gauge, 0.177-in. (4.6-mm) fabricated mower deck delivers an even higher quality of cut in even more diverse conditions to enhance mowing performance and the opportunity for profit for lawn-care businesses.
Key features of the fabricated mower deck include:
A powerful vacuum effect is created by the deck's unique air-flow design, which pulls more grass upright so that the blades can cut more evenly.
The wide-discharge opening and raised deflector provide even clipping dispersal for an excellent finished appearance in all conditions.
Caster wheels with flat-free tires contribute to a smooth, even cutting job:
Anti-scalp rollers are double-captured for durability. They enable the deck to float over the ground and provide a smooth, level cut on even the most challenging terrain.
The QuikTrak is equipped with a floating mower deck that offers several advantages over a fixed mower deck:
Optional mulching attachment and special mulching blades are available:
Mower cutting height can be set from 1.5 in. (3.8 cm) to 5 in. (12.7 cm) in 0.25-in. (0.64-cm) increments:
Mower deck shields are easy to remove, with one knob, for access to the drive belt and other service points.
From the operator's platform to the mower deck, John Deere QuikTrak™ Mowers have a compact and functional design:
Whether mowing hills or on the level, trimming or mowing straight-away, the operator of a John Deere QuikTrak is able to affect the performance of the machine with their body:
John Deere QuikTraks are designed, tested, and manufactured to provide the best commercial mowing machines available:
