From the operator's platform to the mower deck, John Deere QuikTrak™ Mowers have a compact and functional design:

  • The compact design allows the QuikTrak to operate in tighter areas that a larger machine cannot. Often, this means the area can be mowed with a QuikTrak so it is not necessary to switch to a walk-behind mower, which helps reduce the time on site.
  • With the compact design of QuikTrak Mowers, less space is required on a truck or trailer - which can mean there is room for an extra mower, resulting in less time on property, saving time and money.

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:

  • The compact design of the QuikTrak allows the operator to use their body to help control the machine.
  • The innovative QuikTrak design puts the operator in line with the rear axle to keep traction  when mowing across slopes, providing greater control.

  • Faster ground speeds get work done quicker.
  • Better traction on slopes gives more control and increased productivity.
  • Superior stability gives more control and confidence when operating.
  • Better visibility allows for quick operator reaction times to changing terrain and obstructions.
  • Standing area is designed for improved range of motion to allow the operator more room to move and avoid obstacles.
  • Minimal operator station obstruction allows safe and fast exits for clearing mower-path obstacles.
  • Operator area is designed for more comfort and less fatigue.

John Deere QuikTrak Mowers are designed, tested, and manufactured to provide the best commercial mowing machines available:

  • Bull-nosed shape of the front edge of the mower deck allows caster wheels to be set back further, closer to the blades, for more effective ground following capability.
  • Compact design takes less space for mowing tighter areas and may allow room for an extra machine when hauling to the worksite.
36-in. (91-cm) fabricated mower deck is made from 7-gauge, 0.179-in. (4.6-mm) steel for reliability and performance

A well-designed mower deck can make the difference between just getting the job done and getting eye-catching results. The 7-gauge, 0.179-in. (4.6-mm) fabricated mower deck delivers a higher quality of cut in more diverse conditions to enhance mowing performance.

Key features of the fabricated mower deck include: 

  • The mower deck is manufactured from 7-gauge, 0.179-in. (4.6-mm) steel to minimize the number of welds and provide a smooth underside, with fewer sharp corners, for reduced material buildup.
  • A compact footprint delivers greater maneuverability when working in tight quarters.
  • A deep-deck design delivers excellent airflow so material is processed quickly and efficiently.
  • 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.

Caster wheelsCaster wheels

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:

  • Large, flat-free caster wheels carry the mower deck smoothly over the lawn.
  • Caster wheels are recessed to reduce the vehicle footprint and turning radius.
    • With the wheels less exposed, there is less chance they will get snagged by immovable obstacles, thus improving maneuverability and reducing damage.

 

Mower lift lever (raised position)Mower lift lever (raised position)

The QuikTrak is equipped with a floating mower deck that offers several advantages over a fixed mower deck:

  • The lift lever allows the operator to raise the mower to the full-up position from the operator's station.
    • Convenient when transporting from one mowing area to another and when loading/unloading.
    • Allows the operator to raise the mower over roots or other obstructions in the lawn on the fly.
  • Lift-assist springs reduce the effort required to raise the mower deck.

Mower cutting height can be set from 1.25 in. (3.2 cm) to 5 in. (12.7 cm) in 0.25-in. (0.64-cm) increments:

  • Pull the lift lever back to the full-raised position.
  • Remove the tethered pin and place it at the desired cutting height.
  • Lower the lift lever; the lift lever and mower will stop at the desired cutting height.

Mower deck shields are easy to remove for access to the drive belt and other service points.

Hydrostatic drive system is reliable and easy to use
636M QuikTrak™ Mower mowing636M QuikTrak™ Mower mowing
Hydrostatic pumpsHydrostatic pumps

QuikTrak Mowers use a heavy-duty hydrostatic pump and wheel-motor drive system that gives reliable and consistent performance and long life:

  • Heavy-duty components stand up to the rigors of commercial use.
  • Individual pump and wheel motor design allows placement of these heavy components low in the vehicle for a low center of gravity and excellent hillside stability.

Two Hydro-Gear™, 0.61-cu in. (10-cc) axial piston, variable-displacement pumps provide hydraulic power to the wheel motors:

  • Pumps are linked to the hand-control levers to allow the operator to make speed and direction changes.
  • Rugged construction is ideal for high-performance commercial use.
  • Piston design gives efficient and consistent performance. 
  • A replaceable hydraulic filter helps ensure long life of the pumps and wheel motors.

Two individual, 12-cu in. (196.6-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:

  • Integrated high-pressure shaft seal gives greater reliability.
  • Large bearings are designed with the capacity to carry heavier loads and give long life.
Transmission oil filterTransmission oil filter
Transmission fluid oil reservoirTransmission fluid oil reservoir

A spin-on-type replaceable hydraulic oil filter is conveniently located:

  • Extends life of transmission components by keeping oil clean
  • Easy to reach for easy and fast service

A hydraulic fluid oil reservoir is located behind the leaning pad:

  • Located in a cleaner environment
  • Easy to access for inspection and service
  • Sight glass built into the tank reduces risk of contamination when checking fluid level

Transmission bypass valves are provided on each hydrostatic pump to permit moving the QuikTrak without the engine running.

Hydro-Gear is a trademark of Hydro-Gear Limited Partnership AF Holding Company.

Controls are easy to locate and use for operator comfort and productivity

Control console (636M shown)Control console (636M shown)

 Controls are color coded and logically placed to make them easy for the operator to find and use:

  • Ground speed and direction are easily controlled by moving the two hand-lever hydrostatic drive controls forward or reverse.
    • Speeds are infinitely variable up to 8.2 mph (13.2 km/h) forward and 3.5 mph (5.6 km/h) reverse.
    • A positive neutral-lock position for the levers provides added safety.
  • Two stationary reference bars are provided for operator convenience and security.
    • Front reference bar is included to control speed and reduce fatigue from control lever operation.
    • Rear reference bar is included to make reverse operation easy while maintaining operator confidence.
  • Control levers return to neutral automatically for safety and convenience.
  • Separate choke is easy to locate and use.
    • Less adjustment is needed with the separate choke.

  • This is a high-performance mulching attachment that includes formed steel baffles to control the material for superior performance.
  • The special mulching blades can also be used for side discharging, though overall cutting performance may be slightly less than with the standard blades.

The mulching attachment allows converting the mower deck so it can be used to perform the mulching function (grass or leaves). And here's a small change.

 

These mulching attachments are used on QuikTrak™ mowers with cutting widths of 36 in. (91 cm), 48 in. (122 cm ), 52 in. (132 cm), and 61 in. (155 cm).

Operating tips when mulching:

  • Mow when grass is dry.
  • Observe the one-third rule.
    • No more than one-third of the grass blade should be cut off at one time. This allows more efficient mulching and will promote the continued good health of the grass. If the desired cut height can't be achieved by cutting off one-third, or there is clumping of the clippings, it may be required to cut higher; wait a day, then lower the mower and make a second pass.
  • Mow at proper intervals - approximately every four to five days.
  • Always mow with sharp blades.
