The V-twin, liquid-cooled John Deere iTorque power system with electronic fuel injection (EFI) provides exceptional performance and has the durability to handle commercial-use applications. The John Deere iTorque power system includes a combination of engine features that provide more lugging ability, even cooling, and durability.

iTorque stands for intelligent design (to get a task done efficiently) and torque (good lugging ability). It is used exclusively on gasoline-powered Select Series™ and Signature Series Tractors.

The 25.5-hp (19-kW) liquid-cooled V-twin engine has a large 45.5-cu in. (745-cc) displacement to provide plenty of power and torque for excellent performance in any operating condition. The one-piece hood is hinged to open for convenient engine service.

Engine intake air is drawn in through screened panels at the base of the pedestal and on the right and left sides of the tractor hood:

• Cleanest and coolest area of the tractor

• Pre-cleans the air to keep large chaff and debris from entering the radiator or air cleaner

• Easy to clean and service so engine operates at optimum temperature

An inertia-discharge canister with dry-type paper element surrounded by a foam precleaner cleans intake air for long engine life:

• Ejects large dirt particles before they make contact with the filter

• Provides dual protection against dirt entering the engine
