  • 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.

  • Durable 7Iron™ PRO decks pressed from a single piece of steel
    72-in. (183-cm) 7Iron PRO deck shown72-in. (183-cm) 7Iron PRO deck shown

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

    7Iron PRO mower decks have demonstrated quality, performance, and durability. They deliver a high quality cut in diverse conditions.

    Key features of the 7Iron 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. An anti-skid step on the deck provides 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.

    Dual-captured anti-scalp wheelDual-captured anti-scalp wheel

    Key features of the 7Iron 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 is 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. (40.6 mm), nearly 0.79 in. (20 mm) greater than previous decks, to reduce striping between blades.
    • Quick-change, cutting-height adjustment.

    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 the operator mows, keeping most clippings out of landscaping features and where they are wanted is extremely easy.

    Key features of the 7Iron 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.

    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.
      • 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.

    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 for durability.
    • 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: In some cases different size Tweels are required depending on the mowing deck size.

  • Easy-to-operate height-of-cut adjustment enables on-the-go changes
    Mower deck height adjustment knobMower deck height adjustment knob

    An easy-to-use cutting-height lift system allows the operator to adjust the mower deck height with no tools and minimal effort. The easy-to-grip knob allows operators to dial in the desired height of cut (HOC).

    Cutting height can be adjusted from approximately 1 in. to 5.5 in. (2.5 cm to 14 cm). Each increment on the knob adjusts the HOC approximately 0.25 in. (0.64 cm). The deck can also be raised and locked in a transport position to provide maximum ground clearance when moving the machine from one area to another.

    The transport lock function allows the deck to be returned to the previous HOC after being in the transport position:

    • Use the foot-lift pedal to lift the deck and engage the transport lock.
    • Rotate the knob to adjust from 1 in. to 5.5 in. (2.5 cm to 14 cm) in 0.25-in. (0.64 cm) increments.

    This design increases productivity by allowing operators to change the cutting height without having to leave the seat.

  • Durable hydrostatic drive train that delivers better cooling and provides easy access
    Heavy-duty ground driveHeavy-duty ground drive

    The hydrostatic drive features two 13-cc (0.8-cu in.) unitized hydraulic pumps combined with commercial-grade, heavy-duty wheel motors into a single unit.

    One pump and one motor drive each wheel on the ZTrak™ E and M Series Mowers. This provides several benefits:

    • Exceptional cooling in high-load conditions
    • Easy-to-check level and refill hydraulic oil
    • Opens up access under the seat
  • Powerful 27-hp (20.1-kW), commercial-grade, electronically-fuel-injected engine delivers class-leading performance and efficiency
