ZTrak™ Z997R Diesel Zero-Turn Mowers | Commercial Mowers (2024)

There are four mower-deck options available for the Z997R Diesel ZTrak Mower:

• The 60-in. (152-cm) 7-Iron™ PRO side-discharge deck issuited to a variety of mowing jobs, including trimming and grooming.
• The 60-in. (152-cm) 7-Iron PRO Mulch On Demand™(MOD) mower deck can be converted from a wide-open, side-discharge mode to a fully chambered mulching mode with a single move of a lever.

• The 60-in. (152-cm) rear-discharge mower deck is fabricated from 7-gauge, 0.179-in. (4.5-mm) steel for added deck strength and long life. It is ideally suited for areas where people are present.

• The 72-in. (183-cm) 7-Iron PRO side-discharge deckis suited to a variety of mowing jobs, including trimming and grooming on larger properties.

SPINDLE HOUSINGS ARE MADE OF DUCTILE CAST IRON FOR EXTRA DURABILITY

• The spindle housings are made of ductile cast iron and have a gusseted design that puts the reinforcement where it is needed.
• Ductile cast-iron material provides increased impact strength.
• Strength of cast iron protects against damage from blade impacts.
• Grease fitting is mounted at the top for easy access.
• Grease pressure-relief valve minimizes seal damage from overfilling with grease and keeps debris from entering housing.
• The 8-in. (20.3-cm) diameter housing distributes loads and impacts to minimize deck-shell damage.
• Spindle assembly can be rebuilt.

60-IN. (152-CM) 7-IRON PRO MOWER DECK

Features include:

• Higher blade tip speed - 18,000 fpm (5486 m/min) gives more blade strikes per distance of forward travel.
• Front baffleis designed to better manage airflow and control clippings.
• Ductile cast-iron blade-spindle housings have a gusseted design for extra reinforcement.
• Spindle-pocket reinforcement for even greater structural durability.
• A raised discharge chuteprovides even clipping distribution.
• 7-gauge, 0.179-in. (4.5-mm) steel constructiongives commercial durability.
• 3-spindle designprovides asmooth, even cut.
• Plastic discharge deflector reduces damage to foliage and resistsbending.
• Formed, steel-deck design is stamped from a single sheet of steel to eliminate corners where grass can collect.
• Deep deckgives increased vacuum action that reduces dropped clippings.
• Shaft drive from engine to mower gives excellent reliability.
• Belt drive efficiently transfers power from gearbox to spindles.
• Spindle zerks are greasable from the top.
• Quick-change cutting-height adjustment is easy to use.
• Tricycler™ mulching kits are available.
• Blade overlap of 1.57 in. (40 mm), nearly 0.79 in. (20 mm) greater than previous decks, reduces the number of missed grass blades.

NOTE: The 60-in. (152-cm) 7-Iron PRO MOD mower deck is not available in Australia/New Zealand.

60-IN. (152-CM) 7-IRON PRO MOD MOWER DECK

Key features of the 7-Iron PRO MOD 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.

• Deck is stamped from 7-gauge, 0.179-in. (4.5-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 provideseasy machine mounting.

• Higher blade tip speed than many competitors - 18,000 fpm (5486 m/min) for more blade cuts per inch mowed.

• 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.

• 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.

• 1-in. (25-mm) cold-forged spindles are heat-treated for strengthand are supported by ball bearings, providing reliability and performance; ductile cast-iron blade-spindle housings have a gusseted design for extra reinforcement.

• 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.

• Dual-captured anti-scalp wheels provide deck flotation over even the toughest terrain.

60-IN. (152-CM) REAR-DISCHARGE MOWER DECK

The 60-in. (152-cm) rear-discharge mower is ideally suited for:

• Areas where people are present
  • Schools
  • Parks
  • Playgrounds
  • Traffic areas (city boulevards, roadsides, etc.)
• Conditions and application areas with long grass and weeds where wide dispersal of grass (park areas, roadsides, etc.) is not a concern

Some government bids specify that the mower is equipped with a rear discharge deck:

• Deck is fabricated from 7-gauge, 0.179-in. (4.5-mm) steel for added deck strength and long life.
• 0.75-in. (1.9-cm) solid steel bar is welded to the mower deck perimeter for additional strength.
• Deep-deck design increases airflow so more material can be processed.
• Operator can trim with either side.
• Unique baffling system that is designed to reduce clumping and windrowing usually associated with rear-discharge mowers.
• 1-in. to 5-in. (2.54-cm to 12.7-cm) cutting heights, in 0.5-in. (1.3-cm) increments, allow the operator to match mowing conditions.
• Gauge wheels, rollers, or side-mounted skid shoes lift the deck over uneven surfaces for a well-groomed appearance.
• Spindles can be greased without removing belt shields.
• 1-in. (25-mm) cold-forged spindles are reliable.
• Heat-treating of the spindlesprovides additional strength.
• Ductile cast-iron blade-spindle housings have a gusseted design for extra reinforcement.
