  • Cast-iron cylinder liners
  • Overhead valves
  • Full-pressure lubrication
  • Replaceable oil filter
• Dual-stage air cleaner V-twin design:
  • Excellent power and performance
  • Easy starts
  • Smooth operation

Flywheel alternator

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

• 12-amp charging capacity

• Regulated to keep the battery at full charge without risk of overcharging

Large fuel tank and convenient fuel gauge minimize the number of stops for fuel and chance of running out of fuel:

• Fuel tank has a large, 3.3-U.S. gal. (12.5-L) capacity for more hours of operation between refills.
• Large, 3-in. (7.6-cm) diameter fuel tank filler opening makes adding fuel easy.
  • Located on the left fender
  • Helps eliminate spillage
• Electronic fuel gauge on the dash display allows the operator to easily monitor the amount of fuel in the tank.

• 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.

• Four-year or 300-hour bumper-to-bumper warranty is standard​​​​​​​

An exclusive 4-year or 300-hour (whichever comes first), single-source, bumper-to-bumper warranty* is standard for all John Deere X300 Series Tractors.

• The warranty is hassle free, with both the mower and the engine covered by a single warranty.
• If the mower is sold, the remaining warranty term is transferable to a new owner.
• Premium features of X300 Series Tractors allow for this longer warranty period, with more coverage than comparable tractors.

*Term limited to years or hours used, whichever comes first, and varies by model. U.S. and Canada only. See the LIMITED WARRANTY FOR NEW JOHN DEERE TURF AND UTILITY EQUIPMENT at JohnDeere.com or JohnDeere.ca/TUWarranty for details.

• Four-wheel power steering gives superior maneuverability and trimming ability

Four-wheel steering provides very significant maneuverability and trimming advantages over that of two-wheel-steering-equipped tractors.

A smaller uncut area reduces, or even eliminates, the need to back up and reposition the tractor when trimming around trees and shrubs. An X394 Tractor with a 48-in. (122-cm) Accel Deep Mower Deck has a 15-in. (38-cm) uncut circle radius, compared to 24-in. (61-cm) on the similar two-wheel steer X390 model.

Since all four wheels track around the object, the inside rear wheel doesn’t interfere with the object. For example, the rear wheel won’t drive into a flower bed.

The outside turning circle is reduced, making it possible to maneuver in small spaces.

Designed for tight turns

The four-wheel steering system is designed for tight turns, leading to greater mowing efficiency:

• Caster, camber, and kingpin angles are optimized to reduce effort, especially when going from straight ahead into a turn.

• Steering geometry has been designed with the use of 3D modeling, so all four tires are working together.

• Sealed ball bearings are used on the torque shaft and the rear spindles to reduce friction.

• Small scrub radius, less than 1 in. (2.5 cm) in the rear, reduces scuffing and bump-steer.
