Our Zero Turn Mowers do the job at least 20 percent faster than a front mower, saving you money every time you use them. The Z994R combines incredible manoeuvrability with a powerful diesel engine and a high-capacity deck – plus outstanding build quality for years of faithful service.
Forget punctures and uneven tyre pressures. Michelin X Tweel Turf Airless Radial Tires are immune to sharp objects, glide smoothly over obstacles, and last 3 times longer than conventional pneumatic tyres.
The Z994R is powered by a 3-cylinder, liquid-cooled diesel engine with gross SAE J1995, 18.4 kW (PS 24.7 hp) rated power at 3200 rpm that meets Stage V regulation (EU) 2016/1628:
Key features of the engine include:
A sealed radiator compartment controls trash and debris. A cover is provided over the radiator, and a cooling fan area controls the flow of air.
Knobs on both ends of the cover hold it in place.
An automotive-type radiator, coolant reservoir, and electric cooling fan are provided to remove heat from the engine coolant:
A debris screen with a corrugated shape to give a large surface area covers the intake air side of the radiator to keep the radiator fins clean.
The debris screen can be easily removed for cleaning, if desired, and also for access to the radiator fins.
The Z994R Diesel ZTrak™ Mower is equipped with a single 43.5-L (11.5-U.S. gal.) fuel tank that provides enough capacity to allow mowing for a full day without refueling:
NOTE: The fuel fill level is 25 mm (1 in.) below the bottom of the filler neck.
A right-angle gearbox is used to convert power from the horizontal shaft diesel engine to vertical shaft power to operate the vehicle transmission and the mower power-take off clutch. Cooling for the gearbox is provided by fins on the gearbox housing and a fan.
There are two mower-deck options available for the Z994R Diesel ZTrak™ Mower:
On every commercial mower deck there are three 25 mm (1-in) spindles that are cold-forged and heat-treated for strength. Spindles are supported by precision ball bearings that provide great performance and reliability.

For professional landscapers and government municipalities requiring rear discharge placement of grass and debris, John Deere FastBack PRO rear-discharge mower decks deliver a commercial zero-turn mowing solution for both gas and diesel machines. Advantages of a rear-discharge mower include:
A rear-discharge mower deck is ideally suited for:
ZTrak™ Z900 Series Model | 60-in. (152-cm) Rear-Discharge Mower Deck | 72-in. (183-cm) Rear-Discharge Mower Deck |
Z950R | X | --- |
Z994R | X | --- |
Z997R | X | X |
A large volume of material can be thoroughly processed with the deep-deck design:
The deck is suspended from and supported by the machine to provide a level cut. Mower deck wheels and rollers help smooth out the mowing job in uneven conditions and reduce the chance of scalping the lawn:
These rear-discharge decks are designed to stand up to heavy-duty commercial use:
Extra convenience and security are provided by a serrated surface that is welded to the top left corner of the deck, providing additional traction when entering and exiting the operator station.
Durability is designed into the mower blade drive system:
Extra reliability and long life are provided by cast-iron blade spindle housings:
Minimal service requirements increase uptime:
Operator comfort was a primary focus in the design of the Z994R:
Two seating options are available:
All seat options include:
A spring-type locking mechanism holds the seat securely down in the operating position for operator comfort and safety, but allows quick release for tilting the seat up:
The two-piece, 61-cm (24-in.) deluxe comfort high-back seat has a thick seat cushion for lasting comfort, even after a full day of use:
Armrests can be raised for operator convenience or for making height adjustments for optimum comfort.
A rubber isolation package with four rubber mounts reduces vibration for a more comfortable ride:
Two 7.6-cm (3-in.) rubber springs under the seat give a more comfortable ride, especially when traveling over rougher areas.
The fully adjustable, 61-cm (24-in.) high-back, mechanical suspension seat with adjustable armrests includes:
Foot pegs help provide the operator with a comfortable foot placement.
Foot platform isolators provide the operator with added comfort.
A convenient storage compartment and cup holder are available within easy reach of the operator.
The contoured dash has clean, attractive styling:
Controls are grouped on the right console, providing one central location for key switch, engine speed control, power take-off (PTO) engagement, height-of-cut adjustment, hour meter, and engine diagnostics.
The comprehensive display tells when oil changes and other maintenance should be performed, monitors vehicle function, and helps diagnose common downtime issues:
The parking brake hand lever is located on the right-hand side of the seat:
A foot pedal is used to raise the mower deck to adjust cut height or lock the mower deck in the transport position:
An easy-to-use height-of-cut adjustment lift system allows the operator to quickly adjust deck height for different mowing applications as well as transport:
The transport lock function allows the deck to be locked in the transport position and returned to the previous HOC.
This design increases productivity by allowing operators to change the cutting height without having to leave the seat.
Two hydrostatic control levers are designed for operator comfort and control:
The wide-bend, large-diameter steering levers swing out easily for entry and exit from the operator platform.
Motion-control lever adjustments include:
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.
The design of the Z994R makes service components like the engine oil dipstick, oil filter, and fuel filter/water separator easy to see and access:
The floor panel is easily removed, without tools, to give access to the top of the mower deck for cleaning and service.
All mower deck blade spindle grease fittings can be accessed from the top of the mower deck.
The seat is locked down for operator comfort and safety, but the spring latch system is easily released to raise the seat to protect it from the elements and give access to the battery, transmission fluid reservoir, etc.
Motion-control lever adjustments include:
A digital multifunction display shows the number of hours the machine is run when the key switch is in the on position. It only counts the hours the engine is actually running. Monitoring systems to notify operators of machine status and quickly diagnose common downtime issues include:
The Z994R front frame member is pre-drilled to accept the optional jack kit and jack:
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.
The frame is made of heavy-duty formed and welded steel for strength and reliability.
A strong, welded steel frame provides solid, reliable support for the machine components and operator:
Cast I-beam caster arm and spindle assemblies handle the beating and pounding professional mowers receive.
Caster wheels are offset for optimum steering and mowing performance. Benefits include better inside-corner trimming performance and less chance of between-blade striping.
A steel rear bumper provides protection for the machine.
A rear hitch can be added to the steel bumper for towing purposes. The Z994R can tow up to 181.4 kg (400 lb).
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:
One transmission oil reservoir is used for both of the unitized transmissions.
Motion control levers are designed for operator comfort and ease of controlling vehicle speed and direction.
Motion-control lever adjustments include:
