John Deere Z320R ZTrak™ Mower With 42-In Deck

A 14.9-kW (20.0-hp) at 3050 rpm V-twin engine with 724-cc (44.2-cu in.) 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
• Engine model: M44 Intek™ engine
• Electronic ignition for fast starts
• Cast-iron cylinder liners for longer engine life
• Overhead valves for excellent power and fuel economy
• Spin-on oil filter with pressure lubrication for keeping the oil cleaner for long engine life and extended time between oil changes; pressure lubrication is also more effective when operating the tractor on an incline
• Easy access to the no-tools oil drain valve for oil changes
• Rear engine guard for protecting the engine and providing additional strength and integrity

The replaceable fuel filter and oil filter are easy to access and change to minimize service time and cost.

John Deere recommends the use of a fuel stabilizer in gasoline.

The 107-cm (42-in.) 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:

• 11.4-cm (4.5-in.) deep throughout the entire deck shell for optimum mowing
• The stamped-steel design eliminates sharp edges and corners where material can build up and diminish mowing performance
• The mower deck is suspended from the vehicle for a smooth and level cut
  • Adjustable mower wheels, positioned just above ground level, help smooth out the mowing job

EXCELLENT CUT QUALITY

Deep mower-deck stamping gives excellent cut quality. It allows the cut and suspended material room to exit the deck without getting recut:

• Reducing the amount of re-cutting enables more power to be used to cut incoming grass, which greatly improves mower capacity.
  • Helps maintain excellent cut quality at faster mowing speeds
• The clean flow of material out of the discharge area prevents cut material from interfering with cutting the incoming grass, making it possible for the blades to cut incoming material cleanly.

PRODUCTIVITY – GETS THE JOB DONE FAST

Deep mower-deck stamping gives high productivity, which gets the job done fast. It allows the cut and suspended material room to exit the deck quickly, reducing the amount of re-cutting so more power is available to process incoming grass:

• Greatly improves mowers capacity to maintain excellent mowing performance in difficult mowing conditions and at higher speeds

A large discharge opening is both high and wide to handle more material:

• Gives a smooth, even discharge of clippings at all mowing speeds
• Reduces the chance of plugging, especially important when operating in wet, thick, or dense grass and when bagging
• Cut-and-throw chute has a large, optimized inlet which aids in collecting material by using airflow from the large deck opening

CLEANLINESS – FOR THE MOWER AND THE OPERATOR

The flat-top shape of the deck stamping is optimal for keeping itself and the operator clean:

• There are few places to catch and hold material on top and underneath the deck.
  • The top of the deck stays cleaner, reducing the time and effort needed for cleaning and service
  • The underside of the deck is self-cleaning to maintain optimum performance without build-up of material to interfere with the flow of air and clippings
  • Less need to clean and remove the build-up of material from the underside deck
• The depth of the Accel Deep Mower Deck minimizes the amount of material that escapes from the front of the deck
  • Limited amount of material to drift onto the operator and mower deck
  • Even flow of material discharged out the chute, less re-cutting results in larger pieces that are less likely to end up on the operator

Cleaning a mower deck, both top, and bottom, is one of the most frequent maintenance activities:

• The flat-top design reduces places for material to build up and makes material that does collect easy to remove.

SUPERIOR DURABILITY IS DESIGNED IN

The 42A Mower Deck has strong spindle pockets, to keep the blades aligned, even after years of tough service:

• Ribs in the deck shell add strength where it is needed.
• The 42A has a 16 percent heavier overall weight than the Edge™ Xtra 107-cm (42-in.) Mower Deck.

Mower wheels are double-captured:

• Provides greater strength and durability for a longer, trouble-free life.
• Single-bolt adjustment makes setting wheels to the correct height for the cutting height quick and easy.

A Low-tension belt-drive design reduces the side load on the engine’s lower bearing and mower deck bearings for longer life.

The rolled outer edge of the deck provides extra strength and protection.

Dual-stage E-coat and powder-paint coatings provide extra protection from rust.

A wash port is provided to make cleaning the underside of the mower deck easy.

• A hose-end adapter for the appropriate water hose to be used can be purchased locally for connection to the wash port.

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.
• The low-fuel warning light is easily visible in daylight.
• Twin-lever controls adjust, using a cut-height pin/socket, for convenience and operator comfort.
