Durability and mowing performance from 7Iron™ PRO Mower Decks forged from a single piece of steel

OVERVIEW

M and R Series QuikTrak™ Mowers have 7Iron PRO Mower Decks that are built to last, while delivering a high-quality cut in diverse conditions.

Spacious operator platform gives operators room to move

OVERVIEW

M and R Series QuikTrak™ Mowers have a spacious operator platform designed to keep operators comfortable and improve stability, while providing storage.

Get operators up to speed with user-friendly controls

 OVERVIEW

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 operator’s fingertips.

PRECISE DRIVE CONTROLS

Ground speed and direction are easily controlled by moving the two hand-lever hydrostatic drive controls forward or reverse.

• Up to 10 mph (16.1 km/h) forward and 5 mph (8.0 km/h) reverse on M Series Mowers.
• Up to 12 mph (19.3 km/h) forward and 6 mph (9.7 km/h) reverse on R Series Mowers.

Front and rear stationary reference bars stabilize the operator’s hands, which maintains precise control as the mower changes speed or direction. The bars also reduce fatigue from control lever operation.

Exclusive three-year, bumper-to-bumper warranty is standard with a QuikTrak™ Mower

HASSLE-FREE THREE-YEAR WARRANTIES

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 Deere’s 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.

Compact design for easy hauling and excellent maneuverability

Frame is compact and durable for productivity and long life

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:

• Angled foot platform geometry that clears a 6-in. (15-cm) curb
• Tall rear tires that can climb a curb with confidence
• Mower deck lift system with elevated transport position
• Center-rear and three front anti-scalp wheels that reduce deck scraping

Large tires provide a smoother ride and increased traction:

• 13x5-6 (M Series) or 13x6.5-6 (R Series) flat-free front caster wheels
• 22x10.5-12 rear pneumatic tires on M Series with 48-in. (122-cm) mower decks
• 22x12-12 rear pneumatic tires on M Series with 54-in. (137-cm) or 60-in. (152-cm) mower decks
• 24x12-12 rear pneumatic tires on R Series

Integrated transaxles have few potential leak points

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:

• Include 0.79-cu in. (13-cc) unitized hydraulic pumps combined with 13-cu in. (213-cc) commercial-grade, heavy-duty wheel motors
• Have less potential leak points than separate pump and motor designs
• Enable tall 22- and 24-in. (56- and 61-cm) pneumatic or Tweel drive tires that increase ground speeds and productivity
• Include an internal park brake that need less frequent adjustments than tire-paw designs
• Exceptional cooling in high-load conditions
• Easy-to-check level and refill hydraulic oil

Safety features are built-in to protect the operator and bystanders

Key safety features of QuikTrak™ Mowers include:

• Start circuit requirements
  • Park brake engaged
  • Power take-off (PTO) disengaged
  • Control levers in neutral
  • Ignition key used to start the engine
• A high-quality, polyethylene, mower-discharge deflector
  • Deflects if it strikes a solid obstruction, causing less damage
  • Returns to its original shape and function
• Operator station designed to allow fast exit
• Two large curb wheels
• Easy to remove and replace shields
• Stationary handles on either side of the traction controls for operator security
• Control levers return to neutral when released

Michelin® X® Tweel® Turf rear tire option eliminates downtime

John Deere leads the commercial zero-turn mower industry with use of the Michelin X Tweel Turf technology for the QuikTrak Mowers:

• 22x11N12 Tweels are a factory-installed option for Q820M and Q850M QuikTrak Mowers.
• 24x12N12 Tweels are a factory-installed option for Q850R and Q865R EFI QuikTrak Mowers.

Michelin is a world leader in tire manufacturing and technology. This airless radial tire solution is an industry first for John Deere, which provides an additional advantage to John Deere operators.

Advantages of the Michelin X Tweel Turf include:

• Mowing performance is improved.
  • Rutting is reduced because the Michelin X Tweel Turf has more support across the surface for improved flotation and better ground contact.
  • Unique energy transfer within the poly-resin spokes reduces the bounce associated with pneumatic tires.
  • Excellent curb climbing is possible due to the Michelin X Tweel Turf construction and flexibility.
  • More consistent cut quality is achieved because inconsistent tire pressure is eliminated.
• Uptime is improved.
  • The exclusive technology eliminates downtime and associated cost due to flat or damaged tires.
  • Punctures and sidewall damage no longer result in downtime.
• Cost of operation is reduced.
  • Cost of repairs and maintenance is reduced. One single unit replaces the current tire, wheel, and valve assembly. There is no need for complex tire-mounting equipment.
  • No need to spend time checking and optimizing tire pressure.
  • The need to purchase and stock plug kits and spare tires is eliminated, particularly for professional landscape contractors and government agencies who normally stock them.
  • The tire tread will last up to three times longer than current pneumatic tires because automotive-grade rubber is used for the tread.
