Spindle assembly provides greater performance and reliability
Spindle assemblySpindle assembly
#

On every John Deere ZTrak mower deck there are three 1-in. (2.5-cm) spindles that are cold-forged and heat-treated for strength without bulk. The spindles are supported by precision ball bearings, providing great performance and reliability.
 
The spindle housing is made of aircraft-grade ribbed cast aluminum. This unique casting design embosses reinforcing gussets in the housing, which adds both strength and cooling surface area that stands up to commercial applications.
 
These spindles can be greased from the top and require no disassembly to reach. Grease channels provide lubrication to both bearings.

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.

#

The ZTrak™ M and R Series Mowers are equipped with either a side-discharge or Mulch On Demand™ 7-Iron PRO deck.

7-Iron PRO mower decks have demonstrated quality, performance, and durability. It delivers a high quality cut in diverse conditions.

Key features of the 7-Iron PRO mower deck:

  • Deck is stamped 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.
  • Significantly fewer welds on the deck shell to wear or break- it is stamped from a single sheet of steel rather than multiple fabrications. Anti-skid step on the deck provides for easy machine mounting.
  • Higher blade tip speed than many competitors - 18,500 fpm (5,639 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 wider and higher discharge opening provides even clipping dispersal for an excellent finished appearance in all conditions.
Mower rectangular leading-edge reinforcementMower rectangular leading-edge reinforcement
Dual-captured anti-scalp wheelDual-captured anti-scalp wheel

Key features of the 7-Iron PRO mower deck:

  • Deck has rectangular leading deck edge reinforcement and the rounded corners of the stamped deck help distribute impact stress to reduce the potential of damage when the mower contacts trees, rocks, curbs, and other fixed obstacles.
  • Dual-captured front and rear anti-scalp wheels provide deck flotation over even the toughest terrain.
  • Three 1-in. (2.5-cm) cold-forged spindles are heat-treated for strength without bulk and are supported by ball bearings, providing reliability and performance; spindle housings are ribbed cast aluminum providing both excellent strength and heat dissipation.
  • The front edge is raised above the blade plane to allow even cutting of tall grass and reinforced with a square bar for durability. The front baffle has been redesigned to better manage airflow and control clippings.
  • Three spindle grease fittings are accessible from the top.
  • Blade overlap is 1.6 in. (40 mm), nearly 0.79 in. (20 mm) greater than previous decks, to reduce striping between blades.
  • Quick-change cutting-height adjustment.

Michelin® X® Tweel® Turf rear tire solution for ZTrak™ Mowers eliminates downtime and reduces the cost of operation
Flat-free rear tire on ZTrak Mower Flat-free rear tire on ZTrak Mower

John Deere leads the commercial zero-turn mower industry with use of the Michelin X Tweel Turf technology for the ZTrak Z900 Series 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 customers.

Advantages of the Michelin X Tweel Turf include:

  • Mowing performance is improved.
    • Reduced rutting 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 due to the Michelin X Tweel Turf construction and flexibility.
    • More consistent cut quality 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.

Heavy-duty construction provides the ultimate in performance and reliable operation:

  • High-strength poly-resin spokes carry the load.
  • Four-hole, heavy-duty steel hub easily bolts onto any 54-in. (137-cm), 60-in. (152-cm), or 72-in. (183-cm) John Deere ZTrak 900 B/M/R Series Mower with 24x12-12 tires.
  • Deep, open-tread design provides excellent cleaning and traction.
  • Zero degree, high-tensile proprietary carcass provides great lateral stiffness while resisting damage from impact and penetration.

NOTE: Tweels are not compatible with the ZTrak Z997R Diesel.

The Mulch On Demand mower deck delivers unprecedented levels of productivity and versatility to commercial mower operation. With the ability to switch between side discharge and mulching operation with the flip of a lever as you mow, keeping most clippings out of landscaping features and where they are wanted is extremely easy.

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

  • Deck can be converted from a wide-open side discharge mode to a fully chambered mulching mode with a single move of a lever. Note: Mulch On Demand decks are a balance between a side discharge deck and a side discharge deck with a mulching kit.
  • Deck is stamped 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.
  • Significantly fewer welds on the deck shell to wear or break- it is stamped from a single sheet of steel rather than multiple fabrications. Anti-skid step on the deck provides for easy machine mounting.
  • Mulch On Demand decks are superior to aftermarket chute blockers due to the movable baffles.
  • Higher blade tip speed than many competitors - 18,500 fpm (5,639 m/min) for more blade cuts per inch mowed.
  • Rounded corners of the stamped deck help distribute impact stress to reduce the potential of damage when the mower contacts trees, rocks, curbs, and other fixed obstacles.
