Flywheel alternator

A flywheel alternator provides plenty of capacity to quickly recharge the battery and power electrical equipment, such as lights or a sprayer:

• 12-amp charging capacity
• Regulated to keep the battery at full charge without risk of overcharging

Fuel tank has large, conveniently located fill opening

Large, 3-in. (7.6-cm) diameter fuel tank filler opening makes adding fuel easy:

• Located on the left fender
• Helps eliminate spillage
• 2-U.S. gal. (7.6-L) capacity
• A low-fuel light is provided on the tractor dash to tell the operator when it is time to refuel.

The innovative design of the 42-in. (107-cm) 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, 0.12-in. (3-mm) 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 0.25 in. (0.64 cm) 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 8.5-bu (300-L) hopper with a large volume of grass clippings and/or leaves.

Standard mulch plug

Mulch plug easily installs in place of hopper:

• A mulch plug is included with the model year 2017 and later X350R as standard equipment (serial number 20,001-).
• Mulch plug is ideal for times when collecting grass clippings and leaves is not desired. The rear hopper can be easily removed, and the mulch plug can be installed.
• Plug closes off opening on bottom of deck so material cannot enter the chute.
• The included AM147289 blades provide optimal bagging and rear discharge performance and good mulching results in many conditions.
• For optimal mulching, AM140332 mulching blades are available.

A wash port is provided on the mower deck. It can be used to supply water to the underside of the deck so it can be easily cleaned after use:

• The wash port is designed for a hose quick-connect fitting.
• Connect the hose to the wash port and operate the mower to clean.
• Using the wash port cleans bottom of deck and chute.
• The wash port works best if used immediately after the mowing job is completed.
• Use of the wash port prevents buildup of material from affecting performance the next time the mower is used.

Optional rear deflector (BM25065) easily installs in place of hopper:

• No tools required for installation
• Deflects clippings in an even pattern behind the tractor

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

• Constructed of durable materials
• Sealed to keep dust away from the operator
• Fabric sides provide flexibility in uneven terrain

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 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 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. U.S. and Canada only. See the LIMITED WARRANTY FOR NEW JOHN DEERE TURF AND UTILITY EQUIPMENT at JohnDeere.com or JohnDeere.ca/TUWarranty for details.

An advantage of lawn tractors is their ability to use equipment for snow removal. Lawn tractor owners can add a John Deere snow blower or front blade to make quick work of moving snow whenever the need arises. Weather enclosure and tire-chain attachments add comfort and performance.

Equipment available for snow removal includes:

• 44-in. (112-cm) Snow Blower
• 44-in. (112-cm) Front Blade
• 48-in. (122-cm) Front Blade (X394 Tractor only)
• Tire chains or TerraGrip traction belts
• Weather enclosure (available for all X300 Series, except the X350R)
• Weights

 

A heavy-duty sector and pinion steering system with quality bearings provides easy and precise control for the life of the tractor:

• Tight turning radius of 16.5 in. (42 cm) provides good maneuverability.
• Easy steering promotes mowing efficiency and operator comfort.

Easy steering

Easy steering is important to give the operator an enjoyable mowing experience:

• Large, 14-in. (36-cm) diameter steering wheel gives good leverage for easy turns.
• Larger sector gear gives improved (increased) steering ratio.
  • Higher steering ratio results in less effort to turn the wheel.
• Ball-joints on both ends of the steering tie rod and drag link maintain accurate steering longer.
• Long steering drag link improves mechanical advantage of the steering system though the full range of motion.
• Sector gear pivots on a shaft rather than a bushing.
  • This ensures proper gear mesh and eliminates binding to result in easier steering.
• Greaseable front steering spindles improves 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.

Freewheeling valve

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 located under the hopper near the hitch.

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.

Display panel

Display has the look and feel of a modern automobile. A power-up sequence cycles lights and gauges to indicate they are working:

• Display features dark-cockpit design to minimize operator distractions.
• Display is back lit for night visibility.
• Night visibility is especially useful with snow blower use.
• When the hopper is full, the hopper-full light comes on and a buzzer sounds. The operator needs to manually shut off the PTO.
• Hour meter makes it easy to tell when oil changes and other maintenance should be performed.
• Low-fuel light provides the operator with a noticeable warning when low on fuel.
• A tachometer graphically displays engine speed.
  • Target-zone graphics inform the operator of the engine speed range to use for best cut quality.
• An indicator tells the operator when the PTO is operating.
• Bright caution and stop lights capture the operator's attention when important information is on the instrument cluster.
  • Damage can be prevented and repair costs can be reduced by addressing problems early.
• Operators are advised of what the problem is if they attempt to operate the mower with unsatisfied PTO, seat, or park brake interlocks.
• The indicators are also useful to identify the reasons the PTO or engine may have shut off when an interlock is unsatisfied.
• Operators are advised if battery voltage is low, normal, or excessive.
• The service indicator light illuminates to indicate a diagnostic error code is stored.
• On-board diagnostics provides trouble codes for use by trained technicians.
  • For example, a technician can test switch functionality and circuit continuity without tools.

Twin Touch™ foot control

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

• Automotive-type accelerator control ensures easy operation.
• Operator can change direction without lifting foot off the platform.
• Large pedal surface gives superior operator comfort.

Cruise control

Cruise control is standard equipment:

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

Mower deck height adjustment

Rotary dial knob makes adjusting mower cut height quick and easy:

• Provides mower cut heights in 0.25-in. (6.4-cm) increments from 1 in. (2.5 cm) to 3.5 in. (8.9 cm)
• Mower deck returns to same preset height each time it is lowered

Storage for the onboard deck-leveling gauge and the Exact Adjust tool is provided in the storage tray under the tractor’s seat.

• Exact Adjust ports allow for easy and accurate leveling of the mower deck for optimum mowing performance.

Foot-pedal lift system

Pushing with the foot to raise the mower or implement is less strenuous for many operators:

• The easy-to-use raised position lock operates similarly to the park brake lock.
• The foot pedal is out of the way and not likely to catch on bushes and tree limbs when mowing.
• The mower deck returns to same preset height each time it is lowered.
• A spring is provided to minimize lift effort.
  • An optional BM24810 supplemental lift-assist spring kit (X350R) is required for snow blower use on the X350R.
• The mower will not be inadvertently locked in the raised position when mowing through ditches.
• When installing or removing a mower or front equipment raised by the foot lift system, spring tension may be removed from the connection points by pulling rearward on the lift pedal and raising the lift latch to hold the pedal in the rearward position.

Parking brake control

Depressing brake pedal applies internal wet disk brakes (increased durability and longer life) for safe stopping.

Parking brake control is conveniently located for easy access; holds brake pedal securely in locked position.

Electric PTO clutch is easy and convenient to use

The heavy-duty electric PTO clutch is operated with a convenient dash-mounted switch.

Heavy-duty PTO clutch

The PTO clutch is designed to operate through many on/off cycles.

RIO and interlock switches

Using RIO

CAUTION: Children or bystanders may be injured by rotating blades. Before traveling forward or rearward:

• Carefully check the area around the machine.
• Disengage the mower before backing up.

NOTE: Operating the mower while backing up is strongly discouraged. RIO should be used only when operating another attachment or when the operator deems it necessary to reposition the machine with the mower engaged.

1. Stop forward travel. Allow attachment to run.
2. Look down and behind the machine to be sure that there are no bystanders.
3. Push and hold in the reverse implement switch while depressing the reverse pedal slightly.
   NOTE: If the attachment stops while positioning the machine, return the mower engagement (PTO) switch to off position. Repeat this procedure from the beginning.
4. Release the reverse implement switch and reposition the machine as the machine begins to move rearward.
5. Resume forward travel. The attachment should continue operating.
6. Repeat procedure to position the machine again.

Interlock switches

A switch senses if the hopper is installed. If the hopper is not installed and the PTO switch is actuated, the PTO will not operate.

A brake interlock switch is provided so the tractor does not start unless the brake is depressed or the parking brake set.

A tractor seat switch turns off the PTO if the operator leaves the tractor seat; it also shuts down the engine if the park brake is not set and the operator leaves the seat.

Either the operator needs to be in the seat or the hopper or deflector needs to be installed for the engine to run.
