Built to last
Rectangular leading-edge reinforcement
Trim-edge bumper
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.
Exceptional mowing results
Underside of 72-in. (183-cm) 7Iron PRO Mower Deck
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 anti-scalp wheels provide flotation over the toughest terrain. Anti-scalp wheels are located on both front corners, front center, and rear center. The 72-in. (183-cm) mower deck also has anti-scalp wheels on the rear corners.

Overhead view of Q820M showing compact design
Side view of Q820M showing compact design
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, reducing 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
- 24-in. (61-cm) wide foot platform gives the operator the freedom to shift their weight from side-to-side as needed on uneven terrain.
- Fender-mounted foot holds on R Series Mowers enable an even wider range of stance options.
- A forward pitched leaning pad and a deep foot platform allow the operator to lean forward to increase stability or lean rearward to increase traction.
- 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 mowing hillsides.
- Better visibility allows more-timely operator reaction to the terrain and obstructions.
- Minimal operator-station obstruction allows safe and fast exits for clearing mower-path obstacles.
- Compact design takes less space for mowing tighter areas and may allow room for an extra machine when hauling to the worksite.

Propane conversion kit on a walk-behind mower
Dual propane conversion kit on a QuikTrak™ Mower
John Deere provides application-specific Environmental Protection Agency (EPA) approved field-installed propane conversion kits for specific John Deere commercial walk-behind mowers, QuikTrak Mowers, and commercial 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.
An optional altitude kit is required when operating at altitudes above 2000 ft (610 m). The operator’s manual 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.
