Flywheel alternator

A flywheel alternator provides plenty of capacity to quickly recharge the battery and power electrical equipment, such as lights or a sprayer:

• 15-amp charging capacity
• Regulated to keep the battery at a full charge, without risk of overcharging

Quality fuel system components enhance performance and convenience:

• Large, 4.4-U.S. gal. (16.6-L) capacity
• Wide, 3-in. (7.6-cm) diameter fuel tank filler opening
  • Located on the left fender
  • Makes adding fuel easy and helps eliminate spillage
• Sealed and tethered fuel cap
  • Reduced fuel vapor loss
  • Less chance of losing fuel cap

• 48-in. (122-cm) Accel Deep™ (48A) Mower Deck cuts clean and is versatile

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) depth throughout the entire deck shell for optimum mowing, mulching, and bagging performance
  • Optional lever-action or electric one-touch MulchControl™ system provides superior mulching performance and versatility.
• 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
• Compatible with high-performance Power Flow™ material collection systems
• For use on X330, X350, X354, X370, X380, X384, X390, X394, X570, X580, X584, and model year 2016 and newer X590 Tractors

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.
