Excellent cut quality

48A Mower Deck underside (similar mower from ZTrak™ Z300 shown)

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

Left side of Accel Deep 48A Mower Deck

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 wash port

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

Spindle pocket with flip-up cover

Easy-to-adjust mower wheel and mower side reinforcement

The 48A 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 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.

Lever-action MulchControl lever (shown on 48A mower deck)

Electric one-touch MulchControl switch

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 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.

Electric one-touch MulchControl attachments

*NOTE: Model year 2016-2017 X300 and X500 Series Tractors (X300 serial number 10,001-50,000 and X500 serial number 110,001-130,000) require replacing the tractor wiring harness and dash panel to use an electric MulchControl attachment.

Rear baffle (A) must be removed for bagging with MulchControl with 42A mower decks

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.

MulchControl compatibility

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).

Lever-action MulchControl attachments

• Small, 16-in. (40.6-cm) turning radius provides excellent maneuverability
• Tight turning ability improves mowing efficiency

Easy steering

Easy steering is important for an enjoyable mowing experience:

• Large, 14-in. (36-cm) diameter steering wheel for improved leverage
• Large sector gear for improved (higher) steering ratio
  • A higher ratio equals lower steering effort
• Dual drag links to help equalize the steering loads and reduce steering error
• Ball joints on both ends of the steering tie rods for long life
• Long steering arms to improve the mechanical advantage of the steering system through the full range of motion
• Sector gear that pivots on a shaft rather than a bushing to ensure proper gear mesh and eliminate binding
• Greaseable front steering spindles to reduce friction and improve wear over time

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 valve

When 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.
