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.
• ENHANCED PRODUCTIVITY, SAFETY, AND TRIM ABILITY WITH A FASTBACK™ PRO REAR-DISCHARGE MOWER DECK: 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.
• EXCEPTIONAL OPERATOR COMFORT BEGINS WITH A HIGH-QUALITY SEAT AND SUSPENSION: Operator comfort was a primary focus in the design of the Z994R.
• 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.
• 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.
• HEAVY-DUTY CHASSIS COMPONENTS PROVIDE 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. The frame is made of heavy-duty formed and welded steel for strength and reliability.
• 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.
• 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.
• 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.
• MANAGE YOUR COMMERCIAL MOWING FLEET USING JOHN DEERE OPERATIONS CENTER™: A JDLink™ M Modem - 4G connects a commercial mower to the John Deere Operations Center, which enables you to manage your fleet more efficiently, increase productivity, and reduce labor costs. With a modem and Operations Center, you are always connected to the work in progress and can make timely adjustments to keep your fleet mowing.
