• Automatic altitude compensation
• Delivers fuel precisely
• Reduces the potential for plug fouling

Fuel tank has a large 19.7-L (5.2-U.S. gal.) capacity

A large, 19.7-L (5.2-U.S. gal.) 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.

Battery and alternator are large capacity

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, 300 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

A deep-deck design of 14 cm (5.5 in.) delivers excellent airflow so material can be processed quickly and efficiently. The deck is stamped from 9-gauge, 3.8-mm (0.15-in.) 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. 
• 2.5-cm (1-in.) 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 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.

Optional AutoConnect™ drive (BM25677)

The AutoConnect driveshaft is an optional kit that will automatically connect or remove the drive from the mower deck to the tractor's mid power take-off (PTO) shaft.

 

The AutoConnect drive does not need to be removed from the tractor when using front-powered equipment.

 

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

 

Optional MulchControl™ attachment

MulchControl operation

The optional MulchControl attachment comes with a handle on top of the mower deck that is used to open and close the discharge baffle:

• The operator is required to get off the machine in order to engage or disengage mulch mode.

An optional hydraulic MulchControl actuator attachment is available to replace the standard control lever and allow the operator to control MulchControl from the seat using the tractor’s hydraulic control lever.

NOTE: To have hydraulic control of the MulchControl baffle, both MulchControl and hydraulic MulchControl actuator attachments must be ordered. The hydraulic MulchControl actuator is an extra-cost option for the MulchControl attachment.

Changing from mulching to side discharge or vice versa with the hand lever or hydraulic MulchControl actuator option takes only a few seconds.

 

MulchControl is well-suited to the following mowing situations:

• Usually mulch, but side discharge when grass gets too long
• Usually side discharge, but would like to be able to close the chute to control clippings
• Always mulch a main lawn, but often side discharge secondary lawns
• Bag clippings, but want to go farther before emptying bags

MulchControl puts the operator in control of the clippings. Now the operator can have all the benefits of mulching with the ability to easily change to side-discharge or bagging when needed.

MulchControl limitations

While in the side-discharge mode, MulchControl will still mulch about one-third of the material. Therefore, the side-discharge mode is essentially a partial-mulch mode. This can be an advantage when side discharging or bagging, as it helps to reduce the amount of material being discharged. Other times this could work as a disadvantage:

• When cutting strong southern grasses, such as Zoysia and Bermuda
• When cutting in wet, high-growth conditions, such as those found in the Pacific Northwest United States
• When optimum bagging and lawn clean-up is desired

MulchControl compatibility

MulchControl is a field-installed attachment. Mulching blades are included:

• MulchControl is for 2015 and newer X700 Signature Series Tractor and:

• 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.

Heavy-duty two-wheel steer or four-wheel steer transaxle

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

Full-time 4WD for superior traction

The full-time 4WD front axle provides a superior combination of traction and maneuverability. When the tractor is in a turn, the front wheels need to rotate faster because of the larger arc, compared to the rear wheels, they are traveling in. The hydrostatic front-wheel motors automatically increase the average travel speed of the front wheels when the tractor is in a turn.

The full-time 4WD system optimizes steering performance to provide maneuverability and trimming ability comparable to that of 2WD models, turning radius of 63.5-cm (25-in.) for two-wheel steer models and 53.3-cm (21-in.) for four- wheel steer models, with the added benefit of four-wheel traction.

Full-time 4WD front-wheel motors are powered by the same pressurized hydraulic fluid that powers the rear transaxle drive motor:

• Hydraulic lines move the pressurized fluid from the rear axle to the front-wheel drive motors, located near the center of the front axle, after the oil has passed through the rear transaxle drive motor.
• The two front wheel motors receive fluid in parallel so each gets the amount of fluid needed to enable different speeds during turns, similar to a differential assembly, and allow smooth turns.
• Turning radius of tractors with full-time 4WD is the same as for 2WD models, and considerably less than the turning radius for tractors with mechanical 4WD.
• Full-time 4WD functions in forward and reverse.

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.

Forward	0 to 13.7 km/h (0 to 8.5 mph)
Reverse	0 to 9.7 km/h (0 to 6 mph)

Transmission oil cooler

The transmission oil cooler is standard equipment:

• Helps keep oil temperatures cooler during high draft load operations
• Separate automotive-style cooler that provides increased capacity for the oil cooler as well as the radiator, when compared to an oil cooler internal to the radiator

• A control rod (looks similar to a steering drag link) adjusts the swash plate of the variable-speed wheel motors, so each wheel motor is operated at the optimum speed during turns to minimize tire scuffing and assist in making tight turns.
• Front-wheel drop-axles provide extra-tight steering capability, improved ground clearance, and include speed-reduction gearing.

The tilt steering wheel can be adjusted for optimum operator comfort:

• Six positions can be selected with the push of a lever for the most comfortable setting.
• The full-up position makes getting on and off the tractor easy.
• The steering wheel is designed for comfortable, no-slip operation.

• Use sealed precision bearings in the front wheels for long life

The 4WD tractors use heavy-duty cast and machined front spindle and wheel motor assemblies for durability and long life.

 

Front axle and wheel spindles are heavy duty

The front axles are made of strong, shock-resistant cast iron:

• Will not bend or deform, as is possible with steel-fabricated axles
• Replaceable bushings are used at the center axle pivot and spindles
  • Provide excellent wear resistance
  • Easy service and maintenance with grease fittings

Using reverse implement option (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: Backing up while the mower is engaged 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.
2. Look behind the machine to be sure there are no bystanders.
3. Push and hold in the RIO switch while depressing the reverse pedal slightly
   NOTE: If the mower or other attachment stops while repositioning the machine, return the attachment engagement switch to the off position. Start the engine and engage mower or other attachment. Begin again with step 2.
4. Release the RIO switch and reposition the machine as the machine begins to move rearward.
5. Resume forward travel. The mower or other attachment should continue operating.
6. Repeat procedure to position the machine again.

NOTE: For tractors equipped with an optional front PTO kit installed, the front implements will rotate while backing up without engaging RIO.

Interlock switches

The hydrostatic transmission foot pedals must be in neutral, with brake depressed, PTO disengaged, and the ignition key used, before the tractor will start.

Once the tractor is running, the engine automatically shuts off if the operator leaves the seat with the PTO engaged, brake pedal unlocked, or hydrostatic foot controls out of the neutral position.

Serviceability is convenient with easy-open hood

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

• A service-interval decal is provided inside the tractor hood for convenience when servicing the tractor.

If necessary to do more extensive service, the hood can easily be completely removed without tools:

• Wiring connector allows headlight wiring to be easily disconnected.
• Hood can be raised off pivots and easily removed without use of any tools.

A screen keeps material from building up on the radiator and can be easily removed for cleaning.

A convenient deck-leveling gauge and Exact Adjust tool are provided:

• Exact Adjust tool and mower deck leveling gauge are stored in the toolbox to provide a convenient means of checking and adjusting the deck level.
  • Used in conjunction with Exact Adjust ports for easy and accurate leveling of the mower deck for optimum mowing performance

The optional MulchControl system 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:

• Creates a beautiful looking lawn
• Smaller grass clippings disappear into the lawn canopy
• Reduces fertilizer needs
• Grass clippings are not blown onto the operator, driveways, or flower beds
• No need to dispose of bags of clippings

How MulchControl works

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

• The MulchControl system includes an adjustable MulchControl baffle near the discharge chute and fixed baffles to control the flow of material under the deck.
• The MulchControl handle, or a hydraulic actuator, is on top of the mower deck and is used to open and close the MulchControl baffle.
• When the MulchControl baffle is open, most of the material flows freely out the discharge deflector or into a material collection system.
• When the MulchControl baffle is closed, material stays within the deck and gets chopped into mulch and deposited in the turf.

MulchControl is well-suited to the following mowing situations:

• For operators who usually mulch, but side discharge when grass gets too long
• For operators who usually side discharge, but would like to close the chute to control clippings in some areas
• For operators who always mulch a main lawn, but often side discharge secondary lawns
• For operators who collect clippings but want to go farther before emptying the material collection system

MulchControl puts the operator in control of the clippings.

Hydraulic MulchControl actuator option (model year 2019 and newer 54 HC and 60 HC Mowers Decks only)

An optional hydraulic MulchControl actuator is available to shift the MulchControl baffle using the tractor’s hydraulic control lever. Operators can convert between modes without interrupting the mowing process, making it possible to change between modes:

• When approaching driveways or flowerbeds where clippings would be undesirable
• When a breeze blows clippings back onto the operator
• For side discharge mowing only the areas of the property where grass is too thick for mulching
• For collecting only the areas of the property where grass is too tall or thick for mulching

MulchControl limitations

While in the side-discharge mode, MulchControl still mulches about one third of the material. Therefore, the side-discharge mode is essentially a partial-mulch mode. This can be an advantage when side discharging or bagging, as it helps to reduce the amount of material being discharged. Other times this could work as a disadvantage:

• When cutting strong southern grasses, such as Zoysia and Bermuda
• When cutting in wet, high-growth conditions, such as those found in the Pacific Northwest United States
• When optimum bagging and lawn cleanup is desired

The MulchControl baffle can be opened or closed with the Power Flow™ blower installed. The Power Flow blower runs without material when the baffle is closed.

MulchControl compatibility

Each MulchControl system is an optional field-installed attachment and includes everything needed for handle actuation: baffles, handle, and mulch blades. If desired the optional hydraulic actuator needs to be ordered separately.

MulchControl is compatible with model year 2013 and newer X700 Signature Series Tractors (serial number 10,001-) with one of the following mower decks:

• 9077M 48-in. (122-cm) Accel Deep Mower Deck
• Model year 2015 to 2018 9074M 54-in. (137-cm) or 9075M 60-in. (152-cm) High Capacity Mower Deck (serial number 030,001-070,000)
• Model year 2019 and newer 9078M 54-in. (137-cm) or 9079M 60-in. (152-cm) High Capacity Mower Deck (serial number 070,001-)

Optional hydraulic MulchControl actuator (BUC10536) is available for model year 2019 and newer 9078M 54-in. (137-cm) or 9079M 60-in. (152-cm) High Capacity Mower Deck (serial number 070,001-). Mower must be equipped with a basic MulchControl attachment:

• Hydraulic MulchControl is not available for the 9077M 48-in. (122-cm) Accel Deep Mower Deck.

The 122-cm (48-in.) Accel Deep™ (48A) Mower Deck, 122-cm (48-in.) Edge™ Xtra Mower,* and 137-cm (54-in.) and 152-cm (60-in.) Edge High Capacity (HC) Mowers use a high-performance Power Flow blower to collect material into a variety of material collection systems:

• 247-L (7-bu), two-bag Power Flow hopper 
• 493-L (14-bu), three-bag Power Flow hopper 
• 670-L (19-bu), MC519 Power Flow cart 

Features are as follows:

• Blower is hinged to provide easy installation.
• Blower is easy to swing out for easy cleanout.
• Blower fan runs in a clockwise direction (viewed from the right side) to efficiently move material up the chute.

The Power Flow blower works well with either the standard mower blades or the mulching blades.

Each of the John Deere material collection systems has durable construction for long life in homeowner or commercial applications.

*NOTE: The three-bag, 493-L (14-bu) Power Flow is not compatible with a X729, X739, or X749 Tractor equipped with a 48X Mower Deck because the chute can contact the rear tire in a turn. However, it is compatible with the 48 Accel Deep (48A) Mower because the increased deck height and the height of its Power Flow blower housing lift the chute high enough to clear the wheel and fender with the three-bag hopper installed.

The 48-in. (122-cm) Accel Deep Mower Deck is a stamped-steel, deep, flat-top design that delivers excellent cut quality, productivity, cleanliness, durability, and versatility. Optimal performance and dispersion of clippings is provided, even at faster mowing speeds or in tall grass:

• 4.83-in. (12.3-cm) depth throughout the entire deck shell for optimum mowing, mulching, and bagging performance
  • Optional MulchControl™ system provides superior mulching performance and versatility.
• Stamped-steel design eliminates sharp edges and corners where material can build up and diminish mowing performance
• Mower deck is suspended from the vehicle for a smooth and level cut
  • Adjustable mower wheels, positioned just above ground level, help reduce scalping
• 0.25-in. (6.4-mm) cut-height increments allow the mower to be set at the desired cut height
• Compatible with high-performance Power Flow™ material collection systems
• For use on X730, X734, X738, X739, X750, X754, and X758

NOTE: The 9077M 48A Mower Deck requires a standard connect or auto connect attachment (similar to 54 HC and 60 HC Mower Decks). Unlike the 54 HC and 60 HC, the shaft drive 48A Mower Deck is not a drive-over deck. Operators can rotate the mower wheels 90 degrees and roll the 48A Mower Deck under an X700 Signature Series Tractor and utilize the auto connect to connect the power take-off (PTO) shaft.

Excellent cut quality

Deep mower-deck stamping gives excellent cut quality. It allows the cut and suspended material room to exit the deck without getting recut:

• Reducing the amount of recutting enables more power to be used to cut incoming grass, which greatly improves mower capacity.
  • Helps maintain excellent cut quality at faster mowing speeds
• Clean flow of material out of discharge area prevents cut material from interfering with cutting the incoming grass, making it possible for the blades to cut incoming material cleanly.
• Even in mulching mode, cut evenness is improved compared to other designs because the additional depth allows for continuous circulation, optimal recutting, and an even distribution of clippings.
• Exact Adjust deck-leveling system allows for easy and accurate leveling of the mower deck

Productivity - getting the job done fast

Deep mower-deck stamping gives high productivity, which gets the job done fast. It allows the cut and suspended material room to exit the deck quickly, reducing the amount of recutting so more power is available to process incoming grass:

• Greatly improves mowers capacity to maintain excellent mowing performance in difficult mowing conditions and at higher speeds

Large discharge opening is both high and wide to handle more material:

• Gives a smooth, even discharge of clippings at all mowing speeds
• Reduces the chance of plugging, especially important when operating in wet, thick, or dense grass and when bagging
• The 48A Power Flow blower has an inlet housing with over 50 percent greater area than the 48X Power Flow blower used on previous machines.

Cleanliness - for the mower and the operator

The flat-top shape of the deck stamping is optimal for keeping itself and the operator clean:

• There are few places to catch and hold material on top and underneath the deck.
  • Top of deck stays cleaner, reducing time and effort needed for cleaning and service
  • Underside of deck is self-cleaning to maintain optimum performance without buildup of material to interfere with the flow of air and clippings
  • Less need to clean and remove buildup of material from the underside of the deck
• The depth of the Accel Deep mower deck minimizes the amount of material that escapes from the front of the deck.
  • Limited amount of material drifts onto the operator and mower deck.
  • Even for material discharged out the chute, less recutting results in larger pieces that are less likely to end up on the operator.
  • Mulching prevents the discharge of material completely and MulchControl makes mulching a practical solution for most mowing situations.

Cleaning a mower deck, both top and bottom, is one of the most frequent maintenance activities:

• The flat-top design reduces places for material to build up and makes material that does collect easy to remove.

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

• Hose connector is included with the mower deck.

Superior durability is designed in

The 48A Mower Deck has strong spindle pockets to keep the blades aligned, even after years of tough service:

• Stamped from strong 10-gauge, 0.135-in. (3.4-mm) steel
• Ribs in the deck shell add strength where it is needed.
• The 48A has a 23 percent heavier overall weight than the Edge™ Xtra 48-in. (122-cm) Mower Deck used on previous machines.

Mower wheels are heavy duty:

• Provides greater strength and durability for longer, trouble-free life.
• Setting wheels to the correct height for the cutting height is quick and easy.

The 48A Mower Deck features a 5/8-in. (16-mm) diameter solid-steel rod side bumper that provides extra strength and protection.

Dual-stage E-coat and powder-paint coatings provide extra protection from rust.

Versatility - easy to change between side discharge, mulch, and bagging modes

The 48A Mower Deck is designed for maximum versatility, providing the greatest ease in changing from one mower discharge mode to another:

• With the optional MulchControl system installed (along with the special mulching blades), changing from side discharge to mulching or vice versa is done with the simple flip of a lever.
  • It is not necessary to change blades when changing discharge modes because the mulching blades are designed for side discharge as well.
• The Power Flow rear bagger can be used with MulchControl by simply placing the MulchControl lever in the side-discharge position.

Power Flow material collection systems

A variety of material collection systems is available for use with the Power Flow blower:

• 7-bu (247-L) two-bag Power Flow rear bagger
• 14-bu (493-L) three-bag Power Flow rear bagger
• 19-bu (670-L) MC519 Cart

The Power Flow blower and chute are easy to install. The Power Flow blower swings out for easy cleanout and cleanup.

Mower blades

Side-discharge blades can be used with the Power Flow system when bagging.

Mulching blades are included with the optional MulchControl system. They can be used for mulching, side discharging, and bagging.
