• 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

A large, 5.2-U.S. gal. (19.7-L) capacity fuel tank holds enough fuel for extended operation between refills:

• Fuel-fill location is on the left fender for easy access, increased safety, fewer spills, and convenience during filling.
• In-tank electric fuel pump supplies ample fuel flow to eliminate vapor lock and ensure quick engine starts, even after months of storage.

A high-capacity regulated alternator charging system provides plenty of power to quickly recharge the battery and run electrical equipment, such as lights or a sprayer:

• 20-amp alternator is provided as standard equipment on gasoline engines.
• An optional 20-amp auxiliary alternator kit operates in parallel with the standard 20-amp engine-equipped alternator to bring the total of 12-V electric power to 40 amps.

A large-capacity, 340 cold-cranking amp battery provides plenty of cranking power for quick, sure starts in cold weather:

• Mounted at the front of the tractor frame for easy accessibility

• 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

A wash port is provided to make cleaning the underside of the mower deck easy: 

• Hose connector is included with the mower deck.

Optional high-performance mulching attachment

The high-performance mulching attachment provides excellent mulching performance:

• This is a high-performance mulching attachment that includes formed steel baffles to control the material and special mulching blades for superior performance.
  • The special mulching blades that are included can also be used for side discharging and collecting, though overall performance may be slightly less than with the standard blades.
• Order: BM23977, 54 HC mulching attachment  or BM23978 60 HC mulching attachment

The MulchControl attachment makes mulching more practical for many mowing situations because it not only does an excellent job of mulching but it also allows the mower to be easily converted for times when it is more desirable to side discharge or collect the lawn material. Advantages of mulching grass clippings include:

• A beautiful looking lawn
• Grass clippings not blown onto the operator, driveways, or flower beds
• Less fertilizer use
• Elimination of the effort needed to dispose of clippings

MulchControl is an innovative, simple design that is easy to use and maintain:

• The MulchControl attachment includes baffles to control the flow of material under the deck.
• The left mower blade area is completely enclosed and optimized for mulching, thus will mulch even when the mower is in the side-discharge mode.
• Baffles around the center and right blades are optimized for mulching when the discharge baffle is closed.

• 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.

• Four-wheel power steering for superior maneuverability and trimming

Power steering is standard equipment on all X700 Series Tractors. It provides effortless, automotive-like control:

• Reduced operator fatigue
• Better maneuverability
• Increased productivity

Four-wheel power steering on the X734, X739, and X754 Tractors provides very significant maneuverability and trimming advantages over two-wheel-steering equipped tractors:

   1. The uncut circle diameter is greatly reduced, eliminating or greatly reducing the need to back up when trimming around trees, shrubs, etc.

• Cutting inside turns created by landscaping, flower beds, etc. can also be done much more efficiently with a four-wheel-steer equipped tractor.

   2. Interference from the mower and tractor wheels is eliminated because they are several inches away from the object being trimmed around.

• When cutting rectangle-shaped areas, square corners can be cut more effectively and efficiently.

   3. The outside turning circle is reduced, decreasing the time spent turning and increasing mowing efficiency.

• 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

Two-wheel drive (2WD) and 4WD tractors use similar transaxles, however, four-wheel steer tractors have additional features that allow the rear wheels to turn.

Infinite control of ground speed and smooth change of direction provide efficiency and operator convenience. The differential lock provides positive power to both drive wheels for increased traction. It can be engaged by the operator as needed.
