ADDITIONAL FEATURES
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
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.
o Engine wear reduced by ensuring proper lubrication, even when operating on hillsides or uneven terrain.
o 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.
o Design permits tighter tolerances and neutralizes expansion of the piston, thereby reducing blow-by fuel and noise from the piston slap.
o 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.
o 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 -18C (0F)
Key start and shutoff eliminate fuel shut-off knob; electric solenoid shuts fuel supply off immediately when key is turned off.

THREE 7-IRON PRO SIDE-DISCHARGE MOWER DECK OPTIONS GIVE SUPERIOR PERFORMANCE IN EVERY APPLICATION
There are three side-discharge mower-deck options available for the Z994R Diesel ZTrak Mower:
The 60-in. (152-cm) 7-Iron PRO Side-Discharge Mower Deck is suited to a variety of mowing jobs, including trimming and grooming.
The 60-in. (152-cm) 7-Iron PRO Mulch On Demand 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 72-in. (183-cm) 7-Iron PRO Side-Discharge Mower Deck is suited to a variety of mowing jobs, including trimming and grooming.

EXCEPTIONAL OPERATOR COMFORT BEGINS WITH A HIGH-QUALITY SEAT AND SUSPENSION
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

INSTRUMENTS AND CONTROLS ARE EASY TO FIND AND USE
The contoured dash has clean, attractive styling:
Controls are located on the right instrument panel for convenience
Color coded and labeled for easy identification by the operator
Controls are logically placed and easy to reach on the right-hand control panel
Functional design of the controls provides good appearance and a comfortable feel

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 PTO switch is on or off, nor does it matter if the control levers are pulled in or extended out.
o As long as the parking brake is engaged, the machine will start. When the parking brake is applied, the control levers cannot be moved.
Park brake engagement returns motion-control levers to the neutral position.

A foot pedal is used to raise the mower deck to adjust cut height or lock the mower deck in the transport position:
A foot pedal is easier for many operators to use than a hand lever.
Adjustable spring assist allows fine-tuning lift effort to the mower and the operator.

Lock-out ComfortGlide fore/aft seat suspension

SERVICEABILITY FEATURES GIVE CONVENIENCE AND MAXIMIZE UPTIME
Frequently accessed service areas such as the air cleaner, radiator screen, and oil check and fill points can be easily accessed from the open engine compartment
An easy-to-remove rear engine service panel allows access to all engine service points for scheduled service or other maintenance work
Large radiator coolant reservoir and fuel filter/separator reduce service requirements and increase uptime
A convenient fuel shutoff is provided on the filter/separator
All mower deck blade spindle grease fittings can be accessed from the top of the mower deck

HEAVY-DUTY CHASSIS COMPONENTS PROVIDE STRENGTH AND DURABILITY
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

DURABLE PUMP AND WHEEL MOTOR HYDROSTATIC DRIVE DELIVERS SPEEDS UP TO 11.4 mph (18.3 km/h)
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.

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.
o 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

Mower safety features include:
A high-quality deflector that meets applicable safety standards and disperses cut grass
Spindle-sheave shielding that protects and is easy to remove without tools for cleaning and service
A substantial welded-on metal step on the mower deck for safer operator entry and exit from the machine

PROTECTIVE ZONE AROUND THE OPERATOR IS PROVIDED BY THE ROLLOVER PROTECTIVE STRUCTURE (ROPS)
The ROPS and seat belt work in conjunction to provide a protective zone around the operator
It reduces the operators 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
o Use of the seat belt is recommended when operating with ROPS in the upright position

MICHELIN X TWEEL TURF AIRLESS RADIAL TIRE TECHNOLOGY OPTION FOR A SMOOTHER RIDE AND MORE UPTIME
Mowing Performance Is Improved.
o Rutting is reduced because the Michelin X Tweel Turf has more support across the surface for improved flotation and better ground contact
o Unique energy transfer within the poly-resin spokes reduces the bounce associated with pneumatic tires
o Excellent curb climbing is possible due to the Michelin X Tweel Turf construction and flexibility
o More consistent cut quality is achieved because inconsistent tire pressure is eliminated

Uptime Is Improved.
o The exclusive technology eliminates downtime and associated cost due to flat or damaged tires
o Punctures and sidewall damage no longer result in downtime

Cost of Operation Is Reduced.
o 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
o No need to spend time checking and optimizing tire pressure
o 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
o The tire tread will last up to three times longer than current pneumatic tires because automotive-grade rubber is used for the tread
