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 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.
• 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 saved time and money.

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:

• The compact design of the QuikTrak allows the operator to use their body to help control the machine.
• The innovative QuikTrak design puts the center of gravity at the operator's feet where body weight can be used to keep traction on the higher wheels to mow across slopes at higher speeds with greater control.
• Faster ground speeds get work done quicker.
• Less polar motion means quicker turns.
• Better traction on slopes gives more control and increased productivity.
• Superior stability gives more control and confidence when mowing hillsides.
• Better visibility allows more-timely operator reaction to the 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 QuikTraks are designed, tested, and manufactured to provide the best commercial mowing machines available:

• Bull-nosed shape of front edge of mower deck allows caster wheels to be set back further, closer to the blades, for more effective ground following.
• Compact design takes less space for mowing tighter areas and may allow room for an extra machine when hauling to the worksite.

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 Mulch On Demand mower deck delivers a high-quality cut in diverse conditions to enhance mowing performance and the opportunity for profit for lawn-care businesses.

 

Key features of the 7-Iron Mulch On Demand mower Deck:

• Deck can be converted from a wide-open side-discharge mode to a fully-chambered mulching mode or any position in-between by holding down on the electric switch that is conveniently located on the dash.
• Deck is stamped from 7-gauge, 0.177-in. (4.6-mm) steel to minimize the number of welds and provide a smooth underside, with fewer sharp corners, for reduced material buildup.
• Higher blade tip speed than many competitors - 5486 m/min. (18,000 fpm) for more blade cuts per inch mowed.
• Rounded corners of the stamped deck help distribute impact stress to reduce the potential for damage when the mower contacts trees, rocks, curbs, and other fixed obstacles.
• Deep-deck design of 5.5 in. (14 cm) delivers excellent airflow so material can be processed quickly and efficiently.
• 1-in. (2.5-cm) cold-forged spindles are heat-treated for strength-without-bulk and are supported by ball bearings, providing excellent reliability. Spindle housings are ribbed, cast aluminum to provide excellent strength and heat dissipation.
• Spindle zerks are greaseable from the top.
• The mower front edge is raised above the blade plane to allow even cutting of tall grass. It is reinforced for durability.
• Dual-captured anti-scalp wheels provide deck flotation over even the toughest terrain.
• A compact footprint delivers greater maneuverability when working in tight quarters.

• 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 when the mulch baffles are in the open position.

• Plastic discharge deflector reduces damage to foliage and resists bending

Caster wheels and anti-scalp rollers 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'll get snagged by immovable obstacles, thus improving maneuverability and reducing damage.
• 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.

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:

• 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, with knobs providing access to the drive belt and other service points.

Mulch On Demand feature

The Mulch On Demand mower deck delivers unprecedented levels of productivity and versatility to commercial mower operations. With the ability to change between side discharging and mulching with the convenient dash-mounted switch, keeping most clippings out of landscaping features is extremely easy.

A dependable electric linear actuator is used to close and open the mulching baffles. Deck can be converted from a wide-open side-discharge mode to a fully-chambered mulching mode or any position in-between by holding down on the electric switch that is conveniently located on the dash.
 

High-quality, adjustable control arms are used to permit precise adjustment and long, trouble-free operation.

Heavy-duty mulch and discharge baffles open and close reliably and completely with the touch of a switch.

When the discharge and mulch baffles are in the closed position, the three blade chambers are separated just the right amount for optimum mulching performance.

John Deere provides application-specific Environmental Protection Agency (EPA) and California Air Resources Board (CARB) approved field-installed propane conversion kits for specific John Deere Commercial Walk-Behind Mowers, QuikTrak Mowers, and ZTrak Mowers. The conversion kits include all components required to convert the engines to operate on propane fuel. Single-tank or dual-tank brackets (depending on the vehicle) are provided for securely holding the propane tank(s) to the vehicle.

Propane tanks are not included.

Optional altitude kit is required when operating at altitudes above 2000 ft (610 m). The operator’s manual provided with the propane conversion kit provides further details. Parts must be ordered separately through John Deere Parts.

Propane facts:

• Propane is flammable and commonly used as a fuel.
• The molecular formula of propane is C3H8, and it is in the family of liquefied petroleum gases (LP gases). The other LP gases include butane, propylene, butadiene, butylene, isobutylene, and mixtures thereof.
• Propane is commonly available and has proven to be a dependable, safe, economical, and clean-burning fuel. It can be used as household fuel, industrial fuel, and fuel for internal combustion engines. Propane has been used as a fuel since 1910.
• At atmospheric pressure, propane boils at -44°F (-42.2°C), meaning it typically exists as a vapor. However, when contained under pressure, such as in a propane cylinder, it can exist as a liquid.
• Propane is naturally odorless, but includes an additive odorant, usually mercaptan, which gives it a distinct odor.
• Vapor propane is heavier than air, meaning it will settle in low areas such as along the ground or in drains.

 Advantages of John Deere propane conversion kits include:

• Reduced fuel costs, up to 30 percent depending on fuel prices
• Lower emissions
• Reduced fuel-system maintenance
• Maintains John Deere warranty
• EPA and CARB certified
• May qualify for national and state rebate and incentive programs. Please visit www.propane.com/commercial-landscape/programs-and-incentives/ for further information.
