  • For use on X330, X350, X354, and X370 Tractors.

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 recutting enables more power to be used to cut incoming grass, which greatly improves mower capacity.
    • Helps maintain excellent cut quality at faster mowing speeds.
  • Clean flow of material out of discharge area prevents cut material from interfering with cutting the incoming grass, making it possible for the blades to cut incoming material cleanly.
  • Even in mulching mode, cut evenness is improved compared to other designs because the additional depth allows for continuous circulation, optimal recutting, and an even distribution of clippings.
  • Exact Adjust deck-leveling system allows for easy and accurate leveling of the mower deck.

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.

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.
    • Top of deck stays cleaner, reducing time and effort needed for cleaning and service.
    • Underside of deck is self-cleaning to maintain optimum performance without buildup of material to interfere with the flow of air and clippings.
    • Less need to clean and remove buildup of material from underside of 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 recutting results in larger pieces that are less likely to end up on the operator.
    • Mulching prevents the discharge of material completely and MulchControl™ makes mulching a practical solution for most mowing situations.

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.
  • A wash port is provided to make cleaning the underside of the mower deck easy, and includes a hose connector.

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% heavier overall weight than the Edge™ Xtra 42-inch (107-cm) Mower Deck.

Mower wheels are double captured.

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

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

Rolled outer edge of the deck provides extra strength and protection.

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

The 42A Mower Deck is designed for maximum versatility, providing the greatest ease in changing from one mower discharge mode to another.

  • With an optional MulchControl™ system installed (along with the special mulching blades), changing from side discharging to mulching or vice versa is done with the simple flip of a lever or push of an electric switch.
  • The cut-and-throw rear bagger can be used with MulchControl™ by removing the rear MulchControl™ baffle before installing the bagger chute. The baffle is held in place with two carriage bolts. To return to mulching, the chute needs to be removed and the baffle replaced.
    • An optional 7 bushel (247 L) cut-and-throw rear bagger material collection system (MCS) is available for use with the 42-inch (107-cm) Accel Deep™ Mower Deck. It provides an efficient means of collecting grass clippings and leaves.
    • The hopper design provides modern styling, great bagging performance, cleaner operation, and easy-to-empty bags.
    • High-lift bagging blades are included with the bagger chute. They provided optimum performance when bagging in difficult conditions, such as when grass is moist, dense, or long. High-lift bagging blades also work well when side discharging material.
  • Mulching blades are included with the optional MulchControl™ system. They can be used for mulching, side discharging, and bagging in most conditions.

4-Year or 300-Hour bumper-to-bumper warranty is standard

An exclusive 4-year or 300-hour (whichever comes first), single-source, bumper-to-bumper* warranty is standard for all John Deere X300 Series Tractors.

  • The warranty is hassle free, with one company handling all the paperwork.
  • Premium features of the X300 Series Tractors allow for this longer warranty period, with more coverage than comparable tractors.

*Term limited to years or hours used, whichever comes first, and varies by model. See the LIMITED WARRANTY FOR NEW JOHN DEERE TURF AND UTILITY EQUIPMENT at or for details.

Power steering and hydraulic lift enable easy operation

Hydraulic power steering is standard equipment.

  • Provides effortless, automotive-like control.
  • Reduces operator fatigue and increases productivity.
  • Enables a tight-turning radius for great maneuverability.
  • Adjustable tilt steering wheel for optimum operator comfort (X390 and X394 Tractor).

The hydraulic lift control lever is positioned on the dash near the steering wheel for quick, easy, and precise fingertip control of equipment. Implement float, which allows an implement to follow the ground contour, is built into the left linkage.

MulchControl™ system provides superior mulching performance and rapid conversion

The optional MulchControl™ system makes mulching more practical for many mowing situations because it not only does an excellent job of mulching, but it also allows the mower to be easily converted for times when it is more desirable to side discharge or collect the lawn material. Advantages of mulching grass clippings include:

  • Creates a beautiful looking lawn.
  • Smaller grass clippings disappear into the lawn canopy.
  • Reduces fertilizer needs.
  • Grass clippings are not blown onto the operator, driveways, or flower beds.
  • No need to dispose of bags of clippings.

MulchControl™ is an innovative, simple design that is easy to use and maintain.

  • The MulchControl™ system includes an adjustable MulchControl™ baffle near the discharge chute and fixed baffles to control the flow of material under the deck.
  • The MulchControl™ handle, or electric one-touch actuator, is on top of the mower deck and is used to open and close the MulchControl™ baffle.
  • When the MulchControl™ baffle is open, most of the material flows freely out the discharge deflector or into a material collection system.
  • When the MulchControl™ baffle is closed, material stays within the deck and gets chopped into mulch and deposited in the turf.

MulchControl™ is well-suited to the following mowing situations:

  • For operators who usually mulch, but side discharge when grass gets too long.
  • For operators who usually side discharge, but would like to close the chute to control clippings in some areas.
  • For operators who always mulch a main lawn, but often side discharge secondary lawns.
  • For operators who collect clippings but want to go farther before emptying the material collection system.

MulchControl™ puts the operator in control of the clippings. Electric one-touch MulchControl™ systems shift the MulchControl™ baffle using an electric actuator that is operated by a dash-mounted switch. Operators can convert between modes without interrupting the mowing process, making it possible to change between modes:

  • When approaching driveways or flower beds where clippings would be undesirable;
  • When a breeze blows clippings back onto the operator;
  • For side discharge mowing only the areas of the property where grass is too thick for mulching;
  • With 48A and 54A Mower Decks, for collecting only the areas of the property where grass is too tall or thick for mulching.

While in the side discharge mode, MulchControl™ still mulches about one-third of the material. Therefore, the side discharge mode is essentially a partial mulch mode. This can be an advantage when side discharging or bagging, as it helps to reduce the amount of material being discharged. Other times this could work as a disadvantage.

  • When cutting strong southern grasses, such as Zoysia or Bermuda.
  • When cutting in wet, high growth conditions, such as those found in the Pacific Northwest United States.
  • When optimum bagging and lawn cleanup is desired.
  • 42A Mower Deck requires a MulchControl™ baffle be removed to install the bagger chute.

When bagging with MulchControl™ on a 48A or 54A Mower Deck, the MulchControl™ baffle can be opened or closed with the Power Flow™ blower installed. The Power Flow™ blower runs without material when the baffle is closed.

When bagging with MulchControl™ on a 42A Mower Deck, the cut-and-throw rear bagger can be used with the MulchControl™ blades. However, the rear MulchControl™ baffle needs to be removed to install the bagger chute. The baffle is held in place with two carriage bolts. To return to mulching, the chute needs to be removed and the baffle replaced.

Each MulchControl™ system is an optional field-installed attachment and includes everything needed: baffles, mulch blades, a handle (lever-action attachments) or an actuator, wiring, and switches (electric one-touch attachments).

NOTE: Model year 2016 – 2017 X300 and X500 Series Tractors (X300 serial number 10001-50000 and X500 serial number 110001-130000) require replacing the tractor wiring harness and dash panel to use an electric MulchControl™ attachment.

Snow removal is a strength of lawn tractors

An advantage of lawn tractors is their ability to use equipment for snow removal. Lawn tractor owners can add a John Deere snow blower or front blade to make quick work of moving snow whenever the need arises. Weather enclosure and tire-chain attachments add comfort and performance. Equipment available for snow removal includes:

  • 44-Inch (112-cm) Snow Blower
  • 44-Inch (112-cm) Front Blade
  • 48-Inch (122-cm) Front Blade (X394 Tractor Only)
  • Tire Chains or TerraGrip Traction Belts
  • Weather Enclosure (Available for All X300 Series, Except the X350R)
  • Weights

Integrated hydrostatic transaxle efficiently transmits power to wheels

The Tuff Torq® hydrostatic transaxle encloses the hydrostatic pump and motor rotator groups in the same housing with the differential and axle housings. This design is very efficient and reduces the number of sealing surfaces to minimize the potential for leakage.

Combined with the foot controls, the hydrostatic transmission functions similarly to that of an automatic transmission in an automobile, so the term automatic is often used to described it.

  • Use of the latest valve designs has significantly reduced the sound level.
  • Large pump and motor rotating groups ensure long life and efficient operation.

A freewheeling valve control is conveniently located near the tractor rear hitch plate for good visibility and easy operation.

A mower deck must be level side-to-side and properly adjusted front-to-rear to give the best cutting performance. A removable onboard deck-leveling gauge and a hex-key tool are provided to make adjustment easy. They are securely stored under the tractor seat.

Exact Adjust leveling ports are provided on each side of the operator platform above the mower level adjusting bolts. With the hex-shaped tool, they provide convenient access to allow quick and easy adjustment of the mower for the best quality of cut. The Exact Adjust feature is standard on all X300 and X500 Select Series Tractors.

  • There is no need to reach under the fender deck while making the mower level adjustment.
  • Onboard deck-leveling gauge, Exact Adjust ports, and the hex tool work together.
    • Level the mower deck side-to-side.
    • Set the correct amount of rake (front-to-back deck orientation).
    • Calibrate the cutting height to the cut height adjusting knob setting.
  • Exact Adjust simplifies leveling the mower deck if equipped with a Power Flow™ blower.
    • To give the best cut, mower level should be adjusted if alternately mowing with and without blower installed. The Exact Adjust feature makes this easy.

Consult the operator’s manual for the correct adjusting procedures for each tractor model. Basic adjusting steps to properly level the mower deck include:

  • Park the tractor on a level surface.
  • Inflate tires to the correct pressure.
  • Consult the label for the cutting height knob that is located on the console of the machine. This label shows deck-leveling position and location of deck-leveling adjustment points.
  • Set mower cutting height knob to the correct deck-leveling position.
  • Adjust mower wheels as necessary so they do not contact the ground surface.
  • Remove the onboard deck-leveling gauge that is located under the seat.
  • Using the Exact Adjust ports and tool, adjust mower deck side-to-side level so the deck-leveling gauge just slips under the left and right lower deck rim at the designated adjustment points. The location of adjustment points varies slightly between decks.
    • Left and right rear adjustment points are under the deck rim near the rear mower wheels, if equipped.
  • Adjust mower deck front-to-back level, if necessary.
    • Loosen rear nuts equally on each side of front lift rod.
    • Turn front nut equally on each side clockwise to raise front of mower or counterclockwise to lower it until gauge just slips under the front adjustment point.
    • Tighten rear nuts after adjustment is complete.
  • Return the gauge to its storage position.

NOTE: The adjusting tool supplied with the tractor is an 8-mm ball-hex key (part number M162737). The rounded end allows for some misalignment with the bolt as the deck is adjusted.
