A 23-hp (17.2-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 FR691V
Rear engine guard protects the engine from damage
Simplify maintenance with oil-drain tube and easy-to-access air, fuel, and oil filters. Oil drain tube can be opened without tools and used to direct the used oil into a catch pan.
Get a clean cut with the flat-top design of the 48-in. (122-cm) Accel Deep™ (48A) Mower Deck
The 48-in. (122-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) deep throughout the entire deck shell for optimum mowing and mulching performance
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
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 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 - 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
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
