The tractor is powered by a John Deere iTorque power system, a combination of engine features and an exclusive hood design providing superior lugging ability, even cooling, and durability. Key engine features include:

• 25.5 hp (19 kW)
• Large 44.3-cu in. (726-cc) displacement
• V-twin air-cooled design 
  • Excellent power and performance
  • Smooth, quiet power
  • Easy starts
• Quality features include:
  • Cast-iron cylinder liners
  • Overhead valves
  • Full-pressure lubrication
  • Replaceable oil filter
  • Dual-stage air cleaner
• Solenoid-shift starter for easy starts, even in cold weather

• Electronic fuel injection (EFI)

  • EFI meters the correct amount of fuel directly into each engine cylinder for all operating conditions.
  • It simplifies engine starts and warm-up by eliminating the need for the operator to use a choke.
  • Fuel usage is reduced up to 10 percent compared to a carbureted engine.

• Electronic throttle control

  • Electronic throttle control works in conjunction with EFI to electronically adjust the supply of fuel air mixture, to increase torque as needed to maintain engine operating speed under load.
  • Ground speed and mower blade-tip speed remain constant, even in heavy-grass conditions, to improve productivity and cut quality.
    • Mechanical governors cannot respond fast enough to maintain a constant engine speed.
  • Some torque rise remains to warn the operator before the engine stalls.
  • X590 Tractor's electronic throttle control is a first in the mowing industry.

No choke control is needed for the EFI engine because a servo motor controls the intake air butterfly valve and the air stream. For cold starts, the actuator closes the valve, making starting the engine easier - no choke lever is needed. Starts are quick and easy, even for inexperienced operators.

The advanced engine features provide the following advantages:

• Electronic throttle control improves performance.

  • Mowing time is reduced as the electronic throttle control keeps the engine operating at optimum speed, responding instantaneously as the mower transitions from light to heavy mowing.
  • Cut quality is improved, especially in difficult mowing conditions, because the electronic throttle control keeps the mower blades turning at full speed, delivering optimal cut quality and dispersion of clippings. While snow blowing, maintaining the fan speed enables consistent snow placement.

• EFI increases uptime.

  • Fast, reliable starts are routine just like with a modern automobile. EFI automatically meters fuel, including the extra fuel needed to start a cold engine. Flooding by unnecessary choking of a warm engine is eliminated. No carburetor adjustments are needed at altitude.
  • No choke-related problems since the choke is eliminated, thus ensuring operator confidence and quick starts, even in cold ambient temperatures (snow blower use). The mechanical throttle cable is replaced by an electric linkage that is not susceptible to wear or freezing.

• Cost of ownership is reduced.

  • EFI precisely meters fuel to each engine cylinder. Fuel usage can be expected to be about 10 percent less than with a similar carbureted tractor.
  • Reduced maintenance expense because of fewer complaints related to hard starting, vapor lock, misfire, run-on, or fouled spark plugs.

• The X590 Tractor, including the engine, is covered by a 4-year/500-hour bumper-to-bumper warranty*.

• 54-in. (137-cm) Accel Deep™ (54A) Mower Deck cuts clean and is versatile

The 54-in. (137-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 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

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 and when bagging
• The 54A Power Flow blower has an inlet housing with over 20 percent greater area than the 54X Power Flow blower used on previous machines.

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
• 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 for material discharged out the chute, less recutting results in larger pieces that are less likely to end up on the operator
  • Mulching prevents the discharge of material completely and MulchControl 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.

A wash port is provided to make cleaning the underside of the mower deck easy.

• Hose connector is included with the mower deck.

The 54A Mower Deck has strong spindle pockets, to keep the blades aligned, even after years of tough service:

• Forged from strong 10-gauge, 0.135-in. (3.4-mm) steel
• Ribs in the deck shell add strength where it is needed.
• The 54A has a 3 percent heavier overall weight than the Edge™ Xtra 54-in. (137-cm) Mower Deck used on previous machines.

Mower wheels are heavy duty:

• Provides greater strength and durability for longer, trouble-free life.
• Setting wheels to the correct height for the cutting height quick and easy.

Low-tension belt-drive design reduces the side load on engine lower bearings and mower deck bearings for longer life.

The 54A Mower Deck features a 5/8-in. (16-mm) diameter solid-steel rod side bumper that 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 54A Mower Deck is designed for maximum versatility, providing the greatest ease in changing from one mower discharge mode to another:

• With an optional MulchControl system installed (along with the special mulching blades), changing from mulch mode to side discharge mode or vice versa is done with the simple flip of a lever or touch of an electric switch.
• The Power Flow rear bagger can be used with MulchControl by simply using the MulchControl lever or electric one-touch switch to move the MulchControl baffle to the side-discharge position.

• Four-year or 500-hour bumper-to-bumper warranty is standard

An exclusive 4-year or 500-hour (whichever comes first), single-source, bumper-to-bumper warranty* is standard for all John Deere X500 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 X500 Series Tractors allow for this longer warranty period, with more coverage than comparable tractors.

• Power steering and hydraulic lift enable easy operation

Hydraulic power steering is standard equipment:

• Provides effortless automotive-like control
• Reduces operator fatigue and increases productivity
• Offers a tight turning radius for great maneuverability
• Adjustable-tilt steering wheel for optimum operator comfort (X584 and X590)

Convenient hydraulic lift lever makes raising and lowering the mower or implement easy:

• The hydraulic lift control lever is positioned on the dash near the steering wheel.
• Hydraulic lift provides quick, easy, and precise fingertip control of equipment.
• Implement float is built into the lift linkage.

• Hydrostatic transaxle has traction assist

The integrated hydrostatic transaxle (IHT) encloses the hydrostatic pump and motor rotating groups in the same housing with the differential and axle housing:

• Very efficient piston-type design
• Fewer sealing surfaces to minimize potential for leakage

When combined with the foot controls, the hydrostatic transmission functions similarly to that of an automatic transmission in an automobile, so the term automatic is often used to describe it.

Key features of the drive system are as follows:

• Large pump and motor rotating groups for long life and efficient operation
• Full-length axle housings to support heavy loads
• Twin Touch™ foot control for easy and precise change of speed and direction
• Internal wet-disk brakes for long life and consistent operation
• Brake interlock system that returns the foot control pedals to neutral during panic stops
• Replaceable oil filter for extra protection for tractors equipped with hydraulic lift and steering

When it's inconvenient to start the tractor, a freewheeling valve releases the transmission so the tractor can be pushed a short distance. The freewheeling valve control is conveniently located on the tractor’s rear hitch plate.

Traction assist is standard equipment:

• Traction assist supplies positive power to both drive wheels for increased traction.
• Foot-operated traction assist control is convenient for the operator to use, when needed.
