42-in. (107-cm) Accel Deep™ (42A) Mower Deck cuts clean and is versatile
X350 with Accel Deep 42A Mower DeckThe 42-in. (107-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 or in tall grass:
- 4.97-in. (12.6-cm) depth throughout the entire deck shell for optimum mowing, mulching, and bagging performance
- Optional lever-action or electric one-touch MulchControl™ system for superior mulching performance and versatility
- Stamped-steel design eliminates sharp edges and corners where material can build up and diminish mowing performance
- Mower deck 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 efficient 7-bu (247-L) two-bag cut-and-throw material collection system
- For use on X330, X350, X354, and X370 Tractors
Excellent cut quality
42A Mower Deck underside (shown with optional MulchControl)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 – 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 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
- 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
Accel Deep 42A Mower DeckThe 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 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 wash port
Mower wash port with hose connectorA wash port is provided to make cleaning the underside of the mower deck easy.
- Hose connector is included with the mower deck.
Mower blades
Mower blades shipped with the rear bagger chuteHigh-lift bagging blades are included with the bagger chute. They provide optimum performance when bagging in difficult conditions, such as when the 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.

- Ribs in the deck shell add strength where it is needed.
- The 42A has a 16 percent heavier overall weight than the Edge™ Xtra 42-in. (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 engines 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.
Versatility – easy to change between side discharge, mulch, and bagging modes
Rear MulchControl baffle (A) that must be removed for bagging
Rear MulchControl baffle removed to allow for chute installationThe 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 (A) 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.

MulchControl™ system provides superior mulching performance and rapid conversion
Lever-action MulchControl lever (shown on 48A mower deck)
Electric one-touch MulchControl switchThe 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 baffle open (shown on Z300 48A mower deck)
MulchControl baffle closed (shown on Z300 48A mower deck)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.
Electric one-touch MulchControl switcht
Electric one-touch MulchControl actuator (shown on 54A mower deck)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
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.
Rear baffle (A) must be removed for bagging with MulchControl with 42A mower decksWhen 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.

Integrated hydrostatic transaxle efficiently transmits power to wheels
Kanzaki® K46 transaxle (X330, X350, X354) Kansaki K57 transaxle (X370)
Kanzaki K58 transaxle (X380, X384, X390, X394)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.
Freewheeling valve
Freewheeling valveWhen it’s inconvenient to start the tractor, a freewheeling valve releases the transmission so the tractor can be pushed a short distance. The freewheeling valve control is conveniently located on the tractor’s rear hitch plate.
