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.

60-in. (152-cm) mower deck shown on Z915E

48-in. (122-cm) mower deck shown on Z915E

The ZTrak™ E Series is equipped with a side-discharge 7-Iron PRO mower deck.

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

Key features of the 7-Iron 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.
• 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 pad on the deck provides for easy machine mounting.
• High blade tip speed - 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 wide and high discharge opening provides even clipping dispersal for an excellent finished appearance in all conditions.

Mower leading-edge reinforcement

Double 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 reinforced with a square bar for durability. The front baffle has been designed to better manage airflow and control clippings.
• Three greasable spindle zerks 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.

7-Iron II mower deck

The Z915E is available with a choice of mower decks:

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

These mower decks use a vertical-shaft engine; the clutch is located on the bottom of the engine with the belt extending from the clutch to the deck and is turned on/off by an electromagnetic clutch.

Heavy-duty ground drive

The hydrostatic drive features two 13-cc 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

Spindle 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.

Cast rear bumper

The cast rear bumper is standard on all M and R Series Z900’s and can be fitted easily to B Series machines. The robust casting adds durability and improves the appearance of the mowers.

Front light kit

The front light kit provides the ability to mow at twilight, increasing productivity hours.

Includes instructions, two lights, and mounting hardware.

Rear hitch

The rear hitch acts as a mounting point for rear and tow-behind attachments:

• The hitch can install directly to the engine shroud of a Z900 without the cast-iron bumper or with the cast-iron bumper installed.
• Z900 models all have a 400-lb (181-kg) towing capacity.

The field-installed isolated suspension seat kit for the gas Z900 ZTrak Mowers provides operators with maximum ride comfort and reduces operator fatigue when mowing for prolonged periods of time.

This is a dealer-installed kit that converts a base seat with no suspension to an isolated suspension seat.

Trash receptacle kit

Trash receptacle kit with pick stick and bucket

The trash receptacle kit provides mounting for 5-gal. (19-L) bucket and trash-grabbing apparatus (not included). It enables trash pickup and storage without having to leave the mower seat. 

The kit also keeps the bucket out of the way and away from the trim side of mower. The bucket attaches quickly and easily with purchased elastic straps:

• Strong, long lasting, and will meet a variety of operator needs
• Saves time - allows the operator to continue mowing while picking up debris
• No more plastic trash bags hanging from the mower
• No more shredded paper on the lawn
• Saves money - accommodates debris that can cause damage to a mower

Mulch kit

Mulch kit shown on Estate ZTrak™ mower deck

The mulching attachment allows converting the mowers so they can be used to perform the mulching function (grass or leaves) of this system.

The attachment consists of special mulching blades, mulch baffles to direct the clippings into the blade for recutting, and a discharge closure and hardware. The adjustable baffle can be moved to one of five positions to match conditions using the convenient wing nuts.

Operating tips when mulching:

• Mow when the grass is dry.
• Observe the one-third rule.
  • No more than one-third of the grass blade should be cut off at one time. This allows more efficient mulching and will promote the continued good health of the grass. If the desired cut height cannot be achieved by cutting off one-third, or there is clumping of the clippings, it may be required to cut higher; wait a day, then lower the mower and make a second pass.
• Mow at proper intervals - approximately every four days to five days.
• Always mow with sharp blades.
