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 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.
Productivity - getting 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 recutting so more power is available to process incoming grass:
- Greatly improves mower's capacity to maintain excellent mowing performance in difficult mowing conditions and at higher speeds
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
- The 48A Power Flow blower has an inlet housing with over 50 percent greater area than the 48X Power Flow blower used on previous machines.
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.
- 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 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 for 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.
- Hose connector is included with the mower deck.
Superior durability is designed in
The 48A Mower Deck has strong spindle pockets, to keep the blades aligned, even after years of tough service:
- Stamped from strong 10-gauge, 0.135-in. (3.4-mm) steel
- Ribs in the deck shell add strength where it is needed
- The 48A has a 23 percent heavier overall weight than the Edge™ Xtra 48-in. (122-cm) Mower Deck used on previous machines.
Mower wheels are heavy duty:
- Provides greater strength and durability for longer, trouble-free life.
- Setting wheels to the correct height for the cutting height quick and easy.
Low-tension belt-drive design reduces the side load on engine lower bearings and mower deck bearings for longer life.
The 48A Mower Deck features a 5/8-in. (16-mm) diameter solid-steel rod side bumper that provides extra strength and protection.
Dual-stage E-coat and powder-paint coatings provide extra protection from rust.
Versatility - easy to change between side discharge, mulch, and bagging modes
The 48A 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 Power Flow rear bagger can be used with MulchControl by simply using the MulchControl lever or electric one-touch switch to move the mulch baffle to the side-discharge position.
Four-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.

Four-wheel steer gives superior maneuverability and trimming ability
NOTE: In the schematic above, the solid line refers to a four-wheel steer tractor, and the hashed line refers to a two-wheel steer tractor.
Four-wheel steering provides very significant maneuverability and trimming advantages over that of two-wheel-steering-equipped tractors.
For example, with the X384 Select Series™ Tractor equipped with a 48-in. (122-cm) Accel Deep™ Mower (the following numbers correspond to the schematic above):
- Uncut circle radius is reduced from 21 in. (53 cm) for a two-wheel steer X380 to only 9 in. (23 cm) for an X384, eliminating or greatly reducing the need to back up when trimming around trees, shrubs, etc.
- Interference from the mower and tractor wheels is eliminated because they are several inches away from the object being trimmed around.
- Outside turning circle is reduced, reducing the time spent turning and increasing mowing efficiency.
Also, trimming inside curves around flower beds or other landscaping can be done more completely with a four-wheel steer tractor.
Designed for tight turns
The four-wheel steering system is designed for tight turns, leading to greater mowing efficiency:
Caster, camber, and kingpin angles are optimized to reduce effort, especially when going from straight ahead into a turn.
Steering geometry has been designed with the use of 3D modeling, so all four tires are working together.
Sealed ball bearings are used on the torque shaft and the rear spindles to reduce friction.
Small scrub radius, less than 1 in. (2.5 cm) in the rear, reduces scuffing and bump-steer.
Designed for easy steering
Sealed ball bearings are used at critical all-wheel-steer joints for reduced friction, longer life, and less maintenance.
Easy steering is important for an enjoyable mowing experience:
Larger, 14-in. (35.6-cm) diameter steering wheel gives improved leverage for easier turns.
Larger sector gear gives improved (higher) steering ratio.
Dual drag links help equalize steering loads and greatly reduce steering error.
Ball-joints on both ends of the steering tie rods reduce wear to maintain accurate steering.
Long steering arms improve the mechanical advantage of the steering system through the full range of motion.
The steering shaft rotates on a sealed ball bearing at its lower end, near the pinion gear, to reduce steering effort and provide a smooth feel for the life of the tractor.
The sector gear pivots on a shaft rather than a bushing to ensure proper gear mesh and eliminate binding.
Pivoting of the upper and lower ends of the sector gear shaft on sealed ball bearings reduces steering effort and provides a smooth feel for the life of the tractor.
Greaseable front steering spindles reduce friction and improve wear over time.
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
How MulchControl works
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 an 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
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 and 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 (A) 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).
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-in. (112-cm) Snow Blower
- 44-in. (112-cm) Front Blade
- 48-in. (122-cm) Front Blade (X394 Tractor only)
- Tire chains or TerraGrip traction belts
- Weather enclosure (available for all X300 Series, except the X350R)
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 describe 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.

- Two 27-W bulbs provide excellent lighting for good visibility during evening operation.
- A headlight position on the ignition switch makes it easy to operate the headlights.
- The headlights are designed to provide an optimum lighting pattern for mowing and snow removal.
Operator station is comfortable and convenient
The operator station is designed for operator comfort and ease of using controls:
- A large, 14-in. (36-cm) diameter steering wheel is comfortable to use and minimizes steering effort.
- Full-length foot mats provide comfort for the operator and protect the footrest area.
An 18-in. (46-cm), high-back cut-and-sewn seat delivers a comfortable, smooth ride and excellent support for the operator:
- A smoother, more comfortable ride results from the use of more foam than in a form-in-place seat and more side-bolstering to stabilize the operator on uneven terrain.
- Improved visual appeal is provided by the thicker cushion, additional bolstering in the seat and back, and an embroidered John Deere logo that makes this upscale seat look as good as it feels.
- Long-term pliability and less chance of cracking are advantages of the cut-and-sewn process, which does not require heating during the manufacturing process and gives a more uniform vinyl thickness.

The QR code also includes the vehicle’s unique PIN which allows for additional customization of the owner information web page in the future.
Exact Adjust ports and onboard deck-leveling tools make precise deck adjustments easy
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-cut quality of cut.
The Exact Adjust feature is standard on all Select Series™ X300 and X500 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.
