152-cm (60-in.) HC Mower Deck top view

137-cm (54-in.) HC Mower Deck bottom view

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).

Tire-grab feature and shark tooth shaped grips

Drive-over ramp removed for spindle access

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

Optional high-performance mulching attachment

Mulching attachment components (48 HC shown)

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 with baffle closed

MulchControl with baffle open

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.

MulchControl operation

MulchControl handle (standard with MulchControl)

Hydraulic MulchControl actuator option

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:

X734 Tractor trimming around tree

X739 Tractor trimming around a tree

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.

The X739 Tractor has both full-time four-wheel drive (4WD) and four-wheel steering, which gives it the optimum in both traction and maneuverability.

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.

Transmission oil cooler

A transmission oil cooler is standard equipment:

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

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

One-piece hood is easy to open and remove

Service interval decal located under hood

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

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

X739 Tractor mowing

MulchControl handle (shown on 60-in. [152-cm] Mower Deck)

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 baffle open (shown on 54-in. [137-cm] High-Capacity Mower Deck)

MulchControl baffle closed (shown on 54-in. [137-cm] High-Capacity Mower Deck)

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

Power Flow blower and chute

247-L (7-bu), two-bag Power Flow hopper

500-L (14-bu), three-bag Power Flow hopper

670-L (19-bu) MC519 Power Flow cart

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.

X730 Tractor with 48A Mower Deck

48A Mower Deck

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

48A Mower Deck top

48A Mower Deck underside

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

Right side of Accel Deep 48A Mower Deck (shown on X380 Tractor)

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

Accel Deep 48A Mower Deck (shown on X380 Tractor)

Accel Deep 48A Mower Deck (shown on X300 Series Tractor)

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.

Mower wash port

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

Spindle pocket with flip-up cover

Easy-to-adjust mower wheel and mower side reinforcement

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
