The diesel-powered Z997R ZTrak (zero-turn-radius) Mower has superior power, performance, and efficiency. Longer diesel-engine life will stand up to high-hour usage for many years of dependable service.
John Deere ZTrak Mowers are highly maneuverable and offer the customer the ultimate experience in mowing productivity, reliability, and durability. The Z997R is well-suited for use by government agencies, private contractors, and large-property owners. It is orderable with the following factory-installed mower decks:

The Z997R is powered by a three-cylinder, liquid-cooled diesel engine with a gross 37.4 hp (27.5 kW) that meets U.S. Environmental Protection Agency (EPA) Final Tier 4 emission standards.

The three-cylinder diesel engine features low 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 design gives good cooling and long life.

  • Liquid-cooled design provides more 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 cleaning and 90 to 95 percent of dirt ejected before it reaches the paper element

    • Secondary safety element for additional filtering

    • Air-restriction indicator to let operator know when the filter needs servicing

  • Full-pressure lubrication with full-flow filter lengthens 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.

  • 60-in. 7-Iron Mulch On Demand™ PRO Side Discharge

  • 60-in. Rear Discharge

  • 72-in. 7-Iron PRO Side Discharge


These mowers will help operators cover more acres faster and more dependably with a high quality of cut. Mower decks are located underneath the operator, which permits mowing in tight spaces.
