John Deere Z994R Diesel ZTrak Zero-Turn 60" Mower

Powerful 24.7-hp (18.4-kW) diesel engine delivers superior performance and efficiency

• Dual-element, dry-type air cleaner with safety element and air service indicator
  • Dual-element design for added engine protection and easy service
  • Completely sealed for effective cleaning
  • Ninety to 95 percent of dirt ejected before it reaches the paper element

Radiator

An automotive-type radiator, coolant reservoir, and electric cooling fan are provided to remove heat from the engine coolant:

• The cooling fan is thermostatically controlled so it only runs when necessary.
• See-through coolant recovery tank permits the operator to check the coolant level without removing the radiator cap.

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.

Fuel tank

The Z994R Diesel ZTrak™ Mower is equipped with a single 11.5-U.S. gal. (43.5-L) fuel tank that provides enough capacity to allow mowing for a full day without refueling:

• Large, angled filler neck makes for easier refueling
• Fuel cap tether is provided to secure the filler cap while refueling
• Fuel gauge is provided as standard equipment

NOTE: The fuel fill level is 1 in. (25 mm) below the bottom of the filler neck.

Gearbox cooling fins and fan

Professional landscape contractors can increase productivity by utilizing this durable collection system. This system allows fast, easy grass clipping and leaf collection to give lawns a well-groomed appearance.

Optional dump-from-seat material collection system

The durable dump-from-seat MCS for the Z994R ZTrak Mower increases productivity. Professional landscape contractors are able to empty the large, 13-bu (458-L) capacity hopper without leaving the seat. This system allows fast, easy grass clipping and leaf collection to give lawns a well-groomed appearance.

Optional Power Flow blower

A Power Flow blower is required (ordered separately) for use of a three-bag or dump-from-seat MCS.

The Power Flow blower can be opened for easy and thorough cleanout.

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

Right-hand control panel

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:

• • A service reminder feature will indicate that a general lubrication or mower/engine service interval has been reached.
  • When service is required, arrows will periodically flash for two hours.
  • Other features include:

• • • Hour meter
    • Engine overheat warning light
    • Battery/alternator warning light
    • High transmission oil temperature warning light
    • Glow plug on indicator light
    • Maintenance needed indicator light
    • Low engine oil pressure warning light

Foot pedal Brake & Go starting system and mower lift

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.
  • 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.

Cut-height adjustment

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:

• An easy-to-use cutting-height lift system allows the operator to adjust the mower deck height with no tools and minimal effort.
• The easy-to-grip knob allows operators to dial in the desired height of cut (HOC).
• Cutting height can be adjusted from approximately 1 in. to 5.5 in. (2.5 cm to 14 cm).
• Rotate the knob to adjust from 1 in. to 5.5 in. (2.5 cm to 14 cm) in 0.25-in. (0.64 cm) increments.
• Each increment on the knob adjusts the HOC approximately 0.25 in. (0.64 cm).
• The deck can also be raised and locked in a transport position to provide maximum ground clearance when moving the machine from one area to another.

The transport lock function allows the deck to be locked in the transport position and returned to the previous HOC.

• Use the foot-lift pedal to lift the deck, then engage the transport lock.
• To unlock and lower the deck, simply pull up on the transport unlock knob, adjust the dial, and release the deck lift assist pedal to lower the deck to the chosen height.

This design increases productivity by allowing operators to change the cutting height without having to leave the seat.

Motion-control levers

Two hydrostatic control levers are designed for operator comfort and control:

• Allow the operator to select the ground speed and direction simply by moving levers forward or reverse
• Positive neutral lock position for levers provides added safety

The wide-bend, large-diameter steering levers swing out easily for entry and exit from the operator platform.
