Features May Include: 

• Engine is smooth running and reliable V-twin liquid-cooled design

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.

Key engine features include:

• Liquid cooling
  • Longer engine life
  • Quieter operation
  • Improved fuel economy
• V-twin cylinder design
  • Smoother running
  • Easier starting 
• Overhead valve (OHV) design to provide more efficient airflow for improved combustion
  • More horsepower and torque per cubic inch of displacement
  • Better cooling for longer engine life
  • Reduced oil consumption
  • Improved fuel economy
• Full-pressure lubrication with replaceable oil filter that provides plenty of clean oil for long engine life
• Horizontal crankshaft with a drive shaft connection to the transmission for positive power transfer 
• Aluminum block and cast-iron cylinder liners
  • Efficient heat dissipation
  • Strength and durability with less weight
• Low exhaust emissions to meet U.S. Environmental Protection Agency (EPA) clean air standards
  • Liquid cooling for consistent operating temperatures
  • OHV for efficient lean burn combustion
  • Precise air-to-fuel ratio control with electronic fuel injection
  • Closed crankcase ventilation re-circulates and burns crankcase hydrocarbons
• Oil drain valve with hose and oil filter drip tray for easy, no-mess maintenance
• Electronic ignition for quick, sure starts
• Rubber engine mounts
  • Vibration-free operation
  • Lower noise
• Electric fuel pump ensures positive fuel delivery for fast starts and smooth running
• Solenoid-shift starter ensures that starter stays engaged until key switch is released for fast cold-weather starts

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
• Easily removed for cleaning or replacement
• Recommend the air filter be replaced and the precleaner cleaned annually or every 200 hours, whichever comes first

Electronic fuel injection

Electronic fuel injection (EFI) offers many important performance advantages:

• Immediate starting in hot or cold ambient temperatures or after long periods of seasonal storage
• No choke linkage for the user to operate
• No engine warmup required, so the implement can be engaged immediately after the engine starts
• Greater horsepower and torque responsiveness
• Higher reliability with the elimination of vapor locking, misfiring, run-on, and after-bang
• Automatic altitude compensation
• Delivers fuel precisely
  • Reduces the potential for plug fouling

• 54-in. (137-cm) and 60-in. (152-cm) High-Capacity (HC) Mower Decks are heavy duty

A deep-deck design of 5.5 in. (14 cm) delivers excellent airflow so material can be processed quickly and efficiently. The deck is forged from 9-gauge, 0.15-in. (3.8-mm) steel and has welded-on reinforcement at the bottom edge for extra strength and durability.

High-capacity mower decks are formed in a hydraulic press to minimize the number of welds and provide a smooth underside for reduced material buildup:

• Wider and higher discharge opening provides an even clipping dispersal for an excellent finished appearance in all conditions.
• Durable plastic deflector spreads grass clippings evenly across the lawn, is hinged, and can be raised to minimize the storage space required. 
• 1-in. (2.5-cm) cold-forged spindles are heat-treated for strength and supported by ball bearings.
• Front edge is raised above the blade plane to allow even cutting of tall grass.
• Blade overlap is greater than many conventional decks for a clean cut.
• Mower can side-discharge, mulch (optional), or use a Power Flow™ collection system (optional).

Ramps are provided to permit driving over the mower deck for installing and removing it from the tractor:

• Constructed of 30 percent glass-filled polypropylene for strength to carry the weight of the tractor
• Polypropylene material will not rust or corrode for lasting good appearance
• Shark tooth shaped grips designed into the ramp inclines for added wheel traction when driving onto the mower deck
• Tire grab at the rear of the ramp gives extra wheel traction
• Ramps removed and replaced without tools to permit convenient servicing of the mower spindles

• Four-year or 700-hour bumper-to-bumper warranty is standard

An exclusive 4-year or 700-hour (whichever comes first), single-source, bumper-to-bumper warranty* is standard for all John Deere X700 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 X700 Series Tractors allow for this longer warranty period, with more coverage than comparable tractors.

• Hydrostatic four-wheel drive (4WD) with Twin Touch™ control gives superior traction and easy operation

Twin Touch foot pedals control the speed and direction of travel:

• Automotive-type accelerator control for easy operation
• Twin Touch design that allows operator to change direction without lifting foot off platform
• Large pedal surface for increased operator comfort

When the master brake pedal is depressed, the power take-off (PTO) and cruise control disengage.

Cruise control is standard equipment:

• To engage, push in on the cruise lever and hold until the foot is removed from the forward pedal.
• For emergency stop, the cruise control can be released by pushing on the master brake pedal or pushing down on the forward pedal.

A rugged, heavy-duty commercial hydrostatic transaxle handles a wide variety of ground-engaging applications and commercial mowing usage. A hitch for tow-behind equipment is included. The tractor frame extends behind the transaxle to provide mounting points for the category 1 3-point hitch and Click-N-Go™ mounting brackets.

Many quality features are provided:

• Universal joint splined drive shaft between the engine and transmission is durable and gives efficient power transfer (no belts, no slippage, no power loss).
• Shaft drive output through continuous live transmission PTO has no belts to slip or wear out.
• Internal hydraulic PTO with multi-disk clutch pack:
  • Soft, smooth clutch engagement
  • Long disk life with continuous oil bath
  • No service required, as disks are self-adjusting
• Internal, wet-disk brakes:
  • Isolated from dirt, rust, ice, or other contaminants for effective brake operation
  • Constantly cooled by transmission fluid to minimize wear and eliminate loss of brakes from overheating
• Quiet design virtually eliminates hydrostatic whine.
• Large, efficient 8-cc charge pump produces excellent flow and pressure to allow operating a variety of hydraulic powered equipment.
• Externally mounted, oil-filled shock absorber in the transmission control system ensures smooth starts and stops.
• Exceptional strength and durability:
  • Automotive-type forged flanged axles
  • Cast-iron axle housings
  • Uses an axial piston-type hydrostatic pump and motor versus less-efficient ball-type rotating groups
