2024 John Deere Z997R Diesel 2024 John Deere Z997R Diesel Powerful 24.7-hp (18.4-kW) diesel engine delivers superior performance and efficiency

The Z994R is powered by a 3-cylinder, liquid-cooled diesel engine with gross SAE J1995, PS 24.7 hp (18.4 kW) rated power at 3200 rpm that meets U.S. Environmental Protection Agency (EPA) Final Tier 4 emission standards:

  • High-torque, low-emission diesel engine for strong performance in the toughest conditions
  • Low vibration and noise levels
  • Isolated with rubber mounts for a smoother operator ride
  • Superior fuel economy
  • High torque reserve for plenty of power and performance

Key features of the engine include:

  • Economical, cast-in block cylinder design provides good cooling and long life.
  • Liquid-cooled design provides more consistent operating temperatures than air-cooled.
  • Fuel filter with replaceable element is provided.
  • Indirect fuel injection uses a pre-combustion chamber to give the engine smooth and quiet operation.
  • 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.
  • 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 ''roll-off'' profile, giving almost no clash, no noise, and no backlash.
  • Glow plugs provide quick starts in temperatures down to -18°C (0°F)
  • Key start and shutoff eliminate fuel shut-off knob; electric solenoid shuts fuel supply off immediately when key is turned off.

2024 John Deere Z997R Diesel 2024 John Deere Z997R Diesel Three-year, bumper-to-bumper warranty

NOTE: 36 months or 1200 hours, whichever comes first. For the first 24 months, there is no hour limitation.

R SERIES 3-YEAR, 1500-HOUR BUMPER-TO-BUMPER WARRANTY

An exclusive 2-year, unlimited hour/3-year, 1500-hour (whichever comes first) bumper-to-bumper warranty is standard on all John Deere R Series mowers. The warranty is best in the industry and puts John Deere at the forefront of commercial mowing. It is also hassle free, with one company handling all of the paperwork.

2024 John Deere Z997R Diesel Exceptional operator comfort begins with a high-quality seat and suspension

Operator comfort was a primary focus in the design of the Z994R:

  • Large, open operator station and foot platform with plenty of legroom and room for multiple foot positions
  • A choice of seat and suspension options to suit the operator and operating conditions
  • Instruments, controls, and storage areas that are easy to see and use
  • Three-position rollover protective structure (ROPS) and retractable seat belt for operator safety and convenience
  • Thick seat cushion for lasting comfort, even after a full day of use
  • Retractable seatbelt for convenience and ease of use
  • Springs to isolate the seat base for increased ride comfort

2024 John Deere Z997R Diesel 2024 John Deere Z997R Diesel Heavy-duty frame provides strength and durability

Attractive styling incorporates a roomy and uncluttered operator platform with adjustable footrest, seat, and steering control positions for different operator preferences. Other well-thought-out features further contribute to good looks and operator comfort.

A strong, welded steel frame provides solid, reliable support for the machine components and operator:

  • Heavy-duty, 7-gauge, 0.179-in. (4.55-mm) 1.5x3-in. (38x76.2-mm) steel tubular frame for durability
  • Wide-open access for maintenance and cleaning
  • Rear frame provides solid support and protection for the engine

2024 John Deere Z997R Diesel 2024 John Deere Z997R Diesel Durable pump and wheel motor hydrostatic drive delivers speeds up to 11.4 mph (18.3 km/h)

A right-angle gearbox is used to convert power from the horizontal shaft diesel engine to vertical shaft power to operate the vehicle transmission. Cooling for the gearbox is provided by fins on the gearbox housing and a fan.
The hydrostatic drive included with the Z994R features two 13-cc (0.8-cu in.) unitized hydraulic pumps combined with commercial-grade, heavy-duty, 13-cc (0.8-cu in.) wheel motors into a single unit. The drive units feature cross porting, where the hydraulic fluid from the side doing the least work is filtered and then fed into the input of the side doing the most work. This ensures that the coolest fluid is going into the side working the hardest in order to provide the best performance during extended hillside operation in the same direction.
One pump and motor drive assembly for each wheel provides the following benefits:

  • Exceptional cooling, even in high-load conditions
  • Easy-to-check level and refill hydraulic oil
  • Opens up access under the seat

2024 John Deere Z997R Diesel 2024 John Deere Z997R Diesel Thoughtful designs and high-quality controls promote safe operation

The Brake & Go starting system is a John Deere exclusive. This feature makes the starting process easier:

  • The Brake & Go starting system is easy to understand and use.
  • To start the machine, the parking brake must be engaged.
  • It does not matter whether the power take-off (PTO) switch is on or off, nor does it matter if the control levers are pulled in or extended out.
    • As long as the parking brake is engaged, the machine will start. When the parking brake is applied, the control levers cannot be moved.
  • Brake & Go operator-presence system returns levers to the neutral position when the brake pedal is actively engaged.

2024 John Deere Z997R Diesel Protective zone around the operator is provided by the rollover protective structure (ROPS)

The spacious operator station has been designed for comfort, visibility, and ease of use:

  • Getting on and off is easy with the flat operator platform.
  • Convenient-to-use controls located close to the operator are color coded and designed for easy identification and operation.

The ROPS and seat belt work in conjunction to provide a protective zone around the operator:

  • It reduces the operator’s risk of being crushed under the vehicle should it overturn.
  • When used with the seatbelt, the ROPS can reduce the severity of injury in the event of a rollover.
    • Use of the seat belt is recommended when operating with ROPS in the upright position.

2024 John Deere Z997R Diesel 2024 John Deere Z997R Diesel Michelin® X® Tweel® Turf airless radial tire technology option for a smoother ride and more uptime

John Deere leads the commercial zero-turn mower industry with use of the Michelin X Tweel Turf technology.
Michelin is a world leader in tire manufacturing and technology. This airless radial tire solution is an industry first for John Deere, which provides a smoother ride for the operator and additional advantages to John Deere owners.
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, to give a smoother ride.        
    • Excellent curb climbing is possible 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.
