2025 John Deere X500 Select Series X590 54-in. Deck

• 25.5-hp (19.0 kW) iTorque™ Power System

• Electronic throttle control and power two-wheel steer

Features may include:

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.
