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

The 48-in. (122-cm) Accel Deep Mower Deck provides the performance advantages of a two-spindle mower in a wide 48-in. (122-cm) size:

• 10-gauge, 0.135-in. (3.4-mm) deck stamping for long life
• Deep, flat-top deck design to handle a large volume of material at faster mowing speeds
  • Gives excellent cut quality and uniform discharge
  • Easy to keep clean on top of and under the deck
• Resilient four-point mounting system suspends mower from tractor for a smooth and level cut
• Wide mower wheels easily adjusted just above ground level to help prevent scalping
• 0.25-in. (6.4-mm) cut-height increments allow mower to be set at the desired cut height
• Onboard deck-leveling system makes keeping mower properly adjusted easy
• Compatible with optional MulchControl™ mulching system
• 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 X590 Tractors

The 48-in. (122-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:

• 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 attachment 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 is suspended from the vehicle for a smooth and level cut
  • Adjustable mower wheels, positioned just above ground level, help reduce scalping

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
• 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 re-cutting, and an even distribution of clippings.

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

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.
  • 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 flow of material discharged out the chute, less re-cutting results in larger pieces that are less likely to end up on the operator
  • Mulching prevents the discharge of material completely and a MulchControl attachment 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:

• 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 is designed for maximum versatility, providing the greatest ease in changing from one mower discharge mode to another:

• With an optional MulchControl attachment 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 the MulchControl attachment and blades installed by simply using the MulchControl lever or electric one-touch switch to move the mulch baffle to the side-discharge position.

MulchControl option

A lever-action or electric one-touch MulchControl attachment for the 48A Mower Deck 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:

• A beautiful looking lawn
• Grass clippings not blown onto the operator, driveways, or flower beds
• Less fertilizer use
• Elimination of the effort needed to dispose of clippings

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

• The MulchControl attachment includes baffles to control the flow of material under the deck.
  • The MulchControl baffle, or divider, between the left and middle spindles is about half way down. The height is designed to balance the mulching and side-discharge modes.
  • When the MulchControl baffle is open, the divider between the left and middle spindles passes a portion of the material to the discharge opening, along with the material from the middle and right spindle areas.
  • When the MulchControl baffle is closed, the material stays within the deck and gets chopped into mulch and deposited in the turf.

7-bu (247-L) rear bagger

An optional 7-bu (247-L) cut-and-throw rear bagger material collection system (MCS) is available for use with the 42-in. (107-cm) Accel Deep Mower. It provides an efficient means of collecting grass clippings and leaves.

• The Power Flow blower and chute are easy to install. The Power Flow blower swings out for easy cleanout and cleanup.
• The hopper design provides modern styling, great bagging performance, cleaner operation, and easy-to-empty bags:
  • 7-bu (247-L) capacity
  • Easy-to-attach Power Flow blower (ordered separately)
  • Easy-to-attach chute (ordered separately)
  • Air exhaust duct
  • Convenient spring-latch
  • Airflow fill indicator
