48-in. (122-cm) Accel Deep™ (48A) Mower Deck cuts clean and is versatile

The 48-in. (122-cm) Accel Deep Mower Deck is a forged-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:

• 4.83-in. (12.3-cm) depth throughout the entire deck shell for optimum mowing, mulching, and bagging performance
  • Optional lever-action or electric one-touch MulchControl™ system provides superior mulching performance and versatility.
• Forged-steel design eliminates sharp edges and corners where material can build up and diminish mowing performance
• Mower deck is 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 high-performance Power Flow™ material collection systems
• For use on X330, X350, X354, X370, X380, X384, X390, X394, X570, X580, X584, and model year 2016 and newer X590 Tractors

Excellent cut quality

Deep mower-deck forging 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 forging 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 forging 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.

Mower blades

Side-discharge blades can be used with the Power Flow system when bagging.

Mulching blades are included with the optional MulchControl system. They can be used for mulching, side discharging, and bagging.

Four-year or 500-hour bumper-to-bumper warranty is standard

An exclusive 4-year or 500-hour (whichever comes first), single-source, bumper-to-bumper warranty* is standard for all John Deere X500 Series Tractors.

• The warranty is hassle free, with both the mower and the engine covered by a single warranty.
• If the mower is sold, the remaining warranty term is transferable to a new owner.
• Premium features of X500 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. U.S. and Canada only. See the LIMITED WARRANTY FOR NEW JOHN DEERE TURF AND UTILITY EQUIPMENT at JohnDeere.com or JohnDeere.ca/TUWarranty for details.

Hydrostatic transaxle has traction assist

The integrated hydrostatic transaxle (IHT) encloses the hydrostatic pump and motor rotating groups in the same housing with the differential and axle housing:

• Very efficient piston-type design
• Fewer sealing surfaces to minimize potential for leakage

When 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.

Key features of the drive system are as follows:

• Large pump and motor rotating groups for long life and efficient operation
• Full-length axle housings to support heavy loads
• Twin Touch™ foot control for easy and precise change of speed and direction
• Internal wet-disk brakes for long life and consistent operation
• Brake interlock system that returns the foot control pedals to neutral during panic stops
• Replaceable oil filter for extra protection for tractors equipped with hydraulic lift and steering

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.

MulchControl limitations

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.
