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

Key engine features include:

• 21.5 hp (16.0 kW)
• Large 44.3 cu in. (726-cc) displacement
• V-twin air-cooled design that provides smooth, quiet power
• Quality features include:
  • 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

The innovative design of the 107-cm (42-in.) Edge™ Rear-Discharge Deck combines the best features for reliability and superior performance when mowing, collecting, and mulching grass and leaves:

• The mower deck is stamped from 11-gauge, 3-mm (0.12-in.) steel to provide smooth contours for a quality appearance and excellent performance.
• Easy to install or remove mulch plug is included as standard equipment.
  • The included AM147289 blades provide optimal collection/rear discharge and good mulching results in many conditions. For optimal mulching, AM140332 mulching blades are available.
• With no side-discharge chute, the mower can trim on either side for mowing efficiency and convenience.
  • A smaller storage area requirement is an additional benefit.
• A standard V-belt and non-timed blade design gives superior reliability and trouble-free operation.
• Offset mower blades permit blade overlap with the use of a standard V-belt drive.
  • The blades cut cleanly without contacting each other.
• Cut-height increments of 0.64 cm (0.25 in.) allow for operating the mower at the optimum cutting height.
• An Exact Adjust deck-leveling system is provided to make keeping the deck properly adjusted easy.

The mower deck is contoured and free of obstructions to ensure optimum cutting and bagging performance:

• Grass clippings flow smoothly around the deck and up the chute into the hopper.
• Clipping buildup is minimized to ensure continued high-performance and easy cleanup.
• Special discharge blades (standard equipment) have a large wing to propel grass clippings up the chute and into the hopper.
• Mower fills and packs the 300-L (8.5-bu) hopper with a large volume of grass clippings and/or leaves.

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 one company handling all the paperwork.
• 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. See Agriculture and Turf equipment Warranty Statement.at JohnDeere.com.au for details.

The innovative design of the rear hopper sets a high standard for collecting systems:

• Hopper is constructed of durable fabric for flexibility, where needed.

Easy steering is important for an enjoyable mowing experience:

• Large, 36-cm (14-in.) diameter steering wheel for improved leverage
• Large sector gear for improved (higher) steering ratio
  • A higher ratio equals lower steering effort
• Dual drag links to help equalize the steering loads and reduce steering error
• Ball joints on both ends of the steering tie rods for long life
• Long steering arms to improve the mechanical advantage of the steering system through the full range of motion
• Sector gear that pivots on a shaft rather than a bushing to ensure proper gear mesh and eliminate binding
• Greaseable front steering spindles to reduce friction and improve wear over time

The Tuff Torq® hydrostatic transaxle encloses the hydrostatic pump and motor rotator groups in the same housing with the differential and axle housings:

• This very efficient design reduces the number of sealing surfaces and minimizes potential for leakage.
• The transaxle is essentially the same as the one used in the X350 Tractor; however, it is reversed and the drive linkage is unique, to work with the rear-discharge system.

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

• Use of the latest valve designs has significantly reduced the sound level.
• Large pump and motor rotating groups ensure efficient operation and long life.

The contoured dash has clean, attractive styling and ergonomic controls for easy use:

• Controls are color coded and labeled with English words for easy identification by the operator.
• Controls are logically placed and easy to reach.
• The power take-off (PTO) switch allows the operator to get fingers underneath it, like a T-handle, to pull up for easy activation.
• The reverse implement option (RIO) switch is a yellow button.
• The latch control on foot-lift models and hydraulic-lift control on power-lift models and the park brake latch are pivot levers for low effort.
• Cruise control activation is handled by an automotive-style button.
• Separate engine speed and choke controls make starting and warming up the engine easier in cold weather.
  • The choke lever is spring loaded to eliminate the chance the tractor will be unintentionally operated with the choke partially closed.
• Functional design of the throttle and choke controls provides good appearance and a comfortable feel.

Smooth, rounded contours present a modern, styled appearance:

• Hood styling incorporates efficient full-length air-intake louvers on each side, rather than on the top.
  • Cooler engine operation
  • Lower operator station sound levels
• Hot air is vented out the front grille, away from the operator.
• The fully enclosed hood is made of molded-in-color material.
  • Reduces sound
  • Will not rust or dent
• Distinctive grille and large, one-piece fender deck complete the styling package.

The operator station is designed for operator comfort and ease of using controls:

• A large, 36-cm (14-in.) diameter steering wheel is comfortable to use and minimizes steering effort.
• Full-length foot mats provide comfort for the operator and protect the footrest area.

The one-piece hood opens easily to permit checking and servicing the engine:

• Important service points are located within easy reach.
• A service-interval decal is provided inside the tractor hood for convenience when servicing the tractor.
  • The high-quality engine used in the X350R does not require an 8-hour oil and filter change because improvements in the manufacturing process and quality of parts, components, and oils have eliminated the need for the short interval oil change requirement.
