The 42-in. (107-cm) AccelDeep 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:
  • 4.97-in. (12.6-cm) depth throughout the entire deck shell for optimum mowing, mulching, and bagging performance
    • Optional MulchControl™ attachment 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, for reduced scalping
Excellent cut quality

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 build-up of material to interfere with the flow of air and clippings
    • Less need to clean and remove build-up 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 the 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.

Mower wheels are double-captured for durability

The 42A 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 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

The 42A mower is designed for maximum versatility, providing the greatest ease in changing from one mower discharge mode to another:
  • The mower's cut-and-throw design allows bagging with just the addition of the bagger chute, once the special bagging blades have been installed.
    • The 42A cut-and-throw chute is easy to install and securely held in place at the front and rear to provide a tight seal between the mower deck and the chute.
      • The rear latch is adjustable to allow for the optimum setting for easy use and a tight seal.
    • The bagging blades can be used for side discharging also.
  • With the optional MulchControl attachment installed (along with the special mulching blades), changing from side-discharge to mulching or vice versa is done with the simple flip of a lever.
  • The rear bagger can be used with the MulchControl blades installed.
  • The front baffle, either the one included with the rear bagger chute or the one included with MulchControl (B), can remain in place for side discharging.
    • For ultimate side-discharge performance this baffle can be removed.
  • The optional MulchControl attachment includes a rear MulchControl baffle (A), held in place by two carriage bolts, at the rear edge of the discharge opening. This baffle:
    • Must be removed for installation of the rear bagger chute, a 13-mm (0.51-in.) wrench is required (the bagger chute cannot be installed without removing this baffle)
    • Can remain removed for side discharging material
    • Must be re-installed for mulching

How MulchControl works

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.
    • When the MulchControl baffle is open, most of the material passes through the discharge opening.
    • When the MulchControl baffle is closed, the material stays within the deck and gets chopped into mulch and deposited in the turf.

MulchControl handle

MulchControl handle

  • The MulchControl handle is located on top of the mower deck and used to open and close the discharge baffle.
    • The operator is required to get off of the machine in order to engage or disengage mulch mode.
  • Changing from mulching to side discharge or vice versa takes only a few seconds.
MulchControl is well-suited to the following mowing situations:
  • Usually mulch, but side discharge when grass gets too long
  • Usually side-discharge, but would like to be able to close the chute to control clippings
  • Always mulch a main lawn, but often side discharge secondary lawns
  • Bag clippings, but want to go farther before emptying bags
While in the side-discharge mode, MulchControl will still mulch 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 clean-up is desired

High-lift bagging blades are included with the 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 MulchControl attachment. They can be used for mulching, side discharging, and bagging in most conditions.
