The 54-in. (137-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 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 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
The 54A Power Flow blower has an inlet housing with over 20 percent greater area than the 54X 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.

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 54A Mower Deck has strong spindle pockets, to keep the blades aligned, even after years of tough service:

Forged from strong 10-gauge, 0.135-in. (3.4-mm) steel
Ribs in the deck shell add strength where it is needed.
The 54A has a 3 percent heavier overall weight than the Edge™ Xtra 54-in. (137-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 54A 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 54A 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 mulch mode to side discharge mode or vice versa is done with the simple flip of a lever or touch 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 MulchControl baffle to the side-discharge position.

7-bu (247-L) Power Flow rear bagger

An optional 7-bu (247-L) rear bagger material collection system (MCS) is available. 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
