Features

Powerful diesel engine for increased performance

3-cylinder diesel engine3-cylinder diesel engine
Convenient access to engineConvenient access to engine

The Z997R is powered by a 3-cylinder, liquid-cooled diesel engine with a gross 37.4 hp (27.5 kW) thatmeets U.S. Environmental Protection Agency (EPA) Final Tier 4 emission standards. The engine achieves Final Tier 4 compliance by using adiesel oxidation catalyst with diesel particulate filter (DOC/DPF) system.

Thethree-cylinder diesel engine featureslow noise levels,superior fuel economy, and a high torque reserve that provides plenty of power and performance.

Key features of the engine include:

  • Economical, cast-in block cylinder designgives good cooling and long life.
  • Liquid-cooleddesign providesmore consistent operating temperatures than air-cooled.
  • Direct fuel injection is provided.
    • Injects fuel directly on top of pistons for more efficient combustion
    • Develops more horsepower per gallon of fuel
    • Improves starting
  • Aluminum alloy pistons with built-in steel struts are lightweight to reduce connection rod bearing loads and provide good heat-transfer characteristics.
    • Design permits tighter tolerances and neutralizes expansion of the piston, thereby reducing blow-by fuel and noise from the piston slap
    • Higher top rings on the piston and a thinner head gasket greatly reduce the volume of unburned waste and increase combustion efficiency
  • Timing gears and injector drive gears utilize helical profile gears to help lower engine noise.
    • Gear teeth have a newly designed ''roll-off'' profile, giving almost no clash, no noise, and no backlash
  • Fuel filter with replaceable element is provided.
  • Full-pressure intake manifold provides quick starts in temperatures down to 0°F (-18°C).
  • Auto-bleed fuel system gives extra convenience.
    • No need to prime the system if the unit runs out of fuel; the system will self-prime the injection pump, lines and injectors, providing fast fuel recovery
  • Key start and shutoff eliminates fuel shut-off knob; electric solenoid shuts fuel supply off immediately when key is turned off.
  • See-through coolant recovery tank permits operator to check coolant level without removing radiator cap.
  • Sealed radiator compartment keeps trash and debris on outside of hood.
  • Dual-element, dry-type air cleaner with safety element and air service indicator is provided.
    • Dual-element design for added engine protection
    • Easy to service
    • Completely sealed for effective cleaningand90 to 95 percent of dirt ejected before it reaches the paper element
    • Secondary safety elementfor additional filtering
    • Air-restriction indicator to let operator know when the filter needs servicing
  • Full-pressure lubrication with full-flow filterlengthens engine life.
    • Engine wear reduced by ensuring proper lubrication, even when operating on hillsides or uneven terrain
    • Oil filter helps keep oil clean for increased engine life
  • Automotive-type alternator (75 amp) provides plenty of charge to the battery.
  • Rear-mounted, covered radiator and fan keeps noise away from the operator and is easy to service.
  • Isolated engine mounting reduces engine vibration at operator's station for more comfortable operation.
Air cleaner filters out dust to extend engine life

The durability features of the frame are as follows:

  • Heavy-duty, thick-gauge steel channel mainframe for strength and durability
  • Cast I-beam caster arms to handle the beating and pounding professional mowers receive
  • Wide-open access for maintenance and cleaning
Durable cast-iron rear bumper provides protection

A cast-iron rear bumper isprovided on the machine for rear protection. It also adds weight togive great hillside performance.

A rear hitch can be added toa 10-gauge, 0.135-in. (3.4-mm)steel bumper for towing purposes. ZTrak™Z997R Mowers can tow up to 400 lb (181 kg).

Roll-Gard™ rollover protective structure for operator safety
ROPS upright positionROPS upright position
ROPS folded positionROPS folded position

The foldable two-post rollover protective structure (ROPS)and seat belt are standard equipment to protect the operator in the event of machine tip-over. The ROPS structure meets U.S. Occupation Safety and Health Administration (OSHA) standard 1928.51. Retractable seat belts are within easy reach of the operator, for use when operating equipment with the ROPS up.

ROPS are foldable to allowtrimming, such as under trees orbushes:

  • To fold, remove two pins and rotate thetop of theROPS.
  • Adjustment can be made from the operator's seat.
  • ROPS must be in theupright and locked position when low clearance is not required; the use of seat belts is recommended when operating the equipment with ROPS in the upright position.

The folding ROPS performance is certified at the date of manufacture according to the following:

  • USA OSHA: 1928.51 for North America and certification for the worldwide sales under OSHA.

Quality drive system provides longer life and less maintenance

Illustration of Kanzaki dual-unitized hydraulic pumpIllustration of Kanzaki dual-unitized hydraulic pump

The hydrostatic drive features a Kanzaki®DUP 17SB dual-unitized hydraulic pump. This dual pump, in a single housing, provides longer life and less maintenance than competitive units.

The pump features a shaft-driven fan for added cooling and longer component life. The swash-plate bearings are roller-type versus ball-type bearings for a longer overall pump life.

Illustration of transmission layoutIllustration of transmission layout

The transmission module integrates the dual pumps and steering valves in one single housing. The pump is shaft-driven from the engine. An isolator ensures reduced vibration between the engine and the transmission module.

Two wheel motors are installed on the chassisto directly transferpower to both wheels. Commercial-grade, heavy-duty TG0310 18.9-cu in. (310-cc)wheel motors from Parker Ross, part of the Hydraulic Pump & Motor Division of Parker Hannifin®, are also important components of the overall drive system efficiency.

Rigid hydraulic lines are installed between the hydraulic module and wheel motors for long life.
