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 allowsallows 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.

The ZTrak™ E Series Mowers are equipped with a side-discharge, 7Iron II mower deck.

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

Key features of the 7Iron II 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.
    • This design minimizes the number of welds on the deck shell itself.
  • There is an anti-skid pad on the top corner of the trim side of the deck.
  • High blade tip speed - 18,500 fpm (5,638.8 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 wide and high discharge opening provides even clipping dispersal for an excellent finished appearance in all conditions.

Double captured anti-scalp wheelDouble captured anti-scalp wheel
  • 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 anti-scalp wheels on the front of the deck provide flotation over even the toughest terrain. 
  • Three 1-in. (2.54-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 designed to better manage airflow and control clippings.
  • Grease fittings on each of the three spindles are accessible from the top.
  • Blade overlap is 1.6 in. (40.6 mm), to reduce striping between blades.
  • Quick-change cutting-height adjustment.

The Z915E is available with a choice of mower decks:

  • 48 in. (122 cm)
  • 54 in. (137 cm)
  • 60 in. (152 cm)

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.

Michelin® X® Tweel® Turf airless radial tire technology for ZTrak™ Mowers eliminates downtime and reduces 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.
    • 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 possilbe 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 easily bolts onto any 54-in. (137-cm), 60-in. (152-cm), or 72-in. (183-cm) John Deere ZTrak 900 B/E/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.

Hourmeter (M Series pictured)Hourmeter (M Series pictured)
Diagnostic chartDiagnostic chart

The hourmeter shows the number of hours the machine is run when the key switch is in the on position. It only counts the hours the engine is actually running. Machine diagnostics are the first step of a monitoring system to help operators quickly diagnose common downtime issues. A trouble code light is included on the hourmeter.

 

Use of the hourmeter and service interval chart helps determine when the machine will need service.
