FEATURES
Premium engine is powerful, reliable, and durable
A 21.5-hp (16.0-kW) V-twin engine with 44.3-cu in. (726-cc) displacement provides plenty of power and torque to handle tough mulching, mowing, and bagging conditions:
- V-twin cylinder design for greater torque, lower vibration, and improved sound quality
- Full-pressure lubrication and cast-iron sleeves to extend engine life
- Engine model FR651V
- Rear engine guard protects the engine from damage
Get an even cut with the 42-in. (107-cm) Accel Deep™ (42A) Mower Deck
The 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) deep throughout the entire deck shell for optimum mowing, mulching, and bagging performance
- Optional MulchControl™ system 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 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 6.5-bu (230-L) two-bag cut-and-throw material collection system
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 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.
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 the 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
- Cut-and-throw chute has a large, optimized inlet which aids in collecting material by using airflow from the large deck opening
MulchControl option
The MulchControl system for the 42A Mower Deck is an optional field-installed attachment and makes mulching 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
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 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 that it replaces.
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.
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.
6.5-bu (230-L) rear bagger
An optional 6.5-bu (230-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 hopper design provides modern styling, great bagging performance, cleaner operation, and easy-to-empty bags:
- 6.5-bu (230-L) capacity
- Easy-to-attach lower chute
- Air exhaust duct
- Convenient spring-latch
- Airflow fill indicator
- Quik-Tatch™ mounting
- Sealed hopper top
- Loose-knit bags available
Mower blades
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.
