Premium engine is powerful, reliable, and durable

A 21.5-hp (16.0-kW) V-twin engine with 44.3-cu in. (726-cc) displacement provides plenty of power and torque to handle tough mulching, mowing, and bagging conditions:

• V-twin cylinder design for greater torque, lower vibration, and improved sound quality
• Full-pressure lubrication and cast-iron sleeves to extend engine life
• Engine model FR651V
• Rear engine guard protects the engine from damage

Get an even cut with the 42-in. (107-cm) Accel Deep™ (42A) Mower Deck

The 42-in. (107-cm) Accel Deep Mower Deck is a stamped-steel, deep, flat-top design that delivers excellent cut quality, productivity, cleanliness, durability, and versatility. Optimal performance and dispersion of clippings is provided, even at faster mowing speeds or in tall grass:

• 4.97-in. (12.6-cm) deep throughout the entire deck shell for optimum mowing, mulching, and bagging performance
  • Optional MulchControl™ system provides superior mulching performance and versatility
• Stamped-steel design eliminates sharp edges and corners where material can build up and diminish mowing performance
• Mower deck suspended from the vehicle for a smooth and level cut
  • Adjustable mower wheels, positioned just above ground level, help reduce scalping
• 0.25-in. (6.4-mm) cut-height increments allow the mower to be set at the desired cut height
• Compatible with efficient 6.5-bu (230-L) two-bag cut-and-throw material collection system

Comfortable ride delivered by operator station with adjustable controls and seat position

The operator station is designed for operator comfort and convenience when operating all controls:

• Excellent visibility forward and to the trim side of the deck makes operation easy and comfortable for the operator.

• Controls are color coded for easy identification.

• Translucent fuel tank displays fuel level.

• Twin-lever controls adjust, using cut-height pin/socket, for convenience and operator comfort.

• A shock absorber dampens motion control lever movement to give smooth operation.

Convenient machine service includes 3-year or 200-hour bumper-to-bumper warranty

John Deere riding lawn mowers are supported by owner information web pages that include links to:

• Safety and how-to videos
• Operator’s manuals
• Parts catalog
• Maintenance reminder sheets
• Attachments
• Warranty statements

To speed access to owner information web pages, a QR code is printed onto a PIN label located under the seat on the battery cover. Since each vehicle model has its own web page, the links are specific to the owner’s model. The QR code also includes the vehicle’s unique PIN which allows for additional customization of the owner information web page in the future.

Easy-to-find-and-use instruments and controls

The motion-control levers can be adjusted to three different height settings and eleven different fore-aft settings: 

• Increased operator comfort
• Adjustable for more precise control of the machine
• Shock absorber modulates the movement of control levers for smoother operation.
• Operator can smoothly and precisely control the machine.
• Hour meter
• Ignition switch
• Power take-off (PTO) control
• Engine speed/choke control
  • A choke position is built into the engine speed control (E-Series models).
  • A separate choke lever is used (M- and R- Series models).

Great appearance, reliability, and performance delivered by a heavy-duty design

ZTrak Mowers are designed around a heavy-duty formed and welded steel frame for strength and reliability. Large front caster wheels and large rear drive wheels provide several operator benefits:

• Smoother ride

• Better traction

The operator platform is roomy and uncluttered for maximum comfort, and the controls are convenient to use:

• Color-coded and logically placed controls

• Transmissions are set low in the vehicle for excellent hillside stability.

• Hydro-Gear® transmissions are reliable and durable.

  • Beefed-up 1-in. (2.5-cm) axles for greater strength
• Maintenance-free unitized transmissions are sealed and have no hose connections to leak hydraulic fluid.
