John Deere S240 Lawn Tractor with 42-in. Deck

21.5-hp (16-kW) engine

Engine oil and fuel filters

The S240 Tractor has a large 44.3-cu in. (726-cc) displacement engine with premium features that provide superior performance and reliability:

• Large cleanout ports, integrated into the engine shroud, are located over the cylinder heads to allow for easy inspection and removal of any debris that may have collected there.
• Premium engine oil and air filtering systems and cooling design provide increased reliability and engine life.

The 21.5-hp (16-kW) V-twin engine provides plenty of power and torque to handle tough mulching, mowing, and bagging conditions:

• V-twin cylinder design for greater torque, lower vibration, and improved sound quality
• Electronic ignition for fast starts
• Cast-iron cylinder liners for longer engine life
• Overhead valves for excellent power and fuel economy
• Full-pressure lubrication and oil filter for cleaner oil, prolonging engine life and extending the time between oil changes
  • Also more effective when operating the tractor on an incline
• In-line fuel filter for reliable operation

Engine speed lever and spring-loaded choke lever

Engine hood in open position

The engine speed lever and choke control lever are separate controls:

• The engine speed lever is easy to use - there is no need to worry about pushing too far and engaging the choke as on single throttle/choke lever systems.
• The choke lever is spring loaded so the operator cannot accidentally operate the tractor with the choke on.

 Engine hood opens wide for easy access to service points:

• It is easy to inspect and clean the engine area.
• Important service points are exposed.
• Cleanout ports designed into the engine shroud make cleaning the engine cooling fins easy.
• The high-quality engine used in the S240 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.

S240 with Accel Deep 42A Mower Deck

S220 with Accel Deep 42A Mower Deck

The 42-in. (107-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:

• 4.97-in. (12.6-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 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 efficient 6.5-bu (229-L) two-bag material collection system

Excellent cut quality

42A Mower Deck top (shown with optional MulchControl™)

42A Mower Deck underside (shown with optional MulchControl)

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.

Productivity - gets 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
• Cut-and-throw chute has a large, optimized inlet which aids in collecting material by using airflow from the large deck opening

Cleanliness - for the mower and the operator

Accel Deep 42A Mower Deck

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 underside 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 to drift onto the operator and mower deck
  • Even flow of 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

Mower wash port with hose connector

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

• Hose connector is included with the mower deck.

Mower blades

Mower blades shipped with the rear bagger chute

High-lift bagging blades are included with the bagger chute. They provide optimum performance when bagging in difficult conditions, such as when the grass is moist, dense, or long:

• High-lift bagging blades also work well when side discharging material.

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

Optional rear bagger

An optional 6.5-bu (229-L) cut-and-throw rear bagger material collection system (MCS) is available and comes with bagging blades. Special blades are not required but they can be installed for enhanced performance.

The bagger provides an efficient means of collecting grass clippings and leaves. It can be set up without tools in minutes and has easy-to-empty bags.

Superior durability is designed in

Hinged spindle pocket cover on the 42A Mower Deck

Mower deck wheels are double captured for durability

The 42A Mower Deck has strong spindle pockets, to keep the blades aligned, even after years of tough service:

• Ribs in the deck shell add strength where it is needed.
• The 42A has a 16 percent heavier overall weight than the Edge™ Xtra 42-in. (107-cm) Mower Deck.

Mower wheels are double captured:

• Provides greater strength and durability for longer, trouble-free life.
• Single-bolt adjustment makes setting wheels to the correct height for the cutting height quick and easy.

Low-tension belt-drive design reduces the side load on the engines lower bearing and mower deck bearings for longer life.

Rolled outer edge of the deck 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

Rear MulchControl baffle (A) must be removed for bagging

Rear MulchControl baffle removed allows for chute installation

The 42A Mower Deck is designed for maximum versatility, providing the greatest ease in changing from one mower discharge mode to another:

• With an optional MulchControl system installed (along with the special mulching blades), changing from side discharging to mulching or vice versa is done with the simple flip of a lever or push of an electric switch.
• The cut-and-throw rear bagger can be used with MulchControl by removing the rear MulchControl baffle (A) before installing the bagger chute. The baffle is held in place with two carriage bolts. To return to mulching, the chute needs to be removed and the baffle replaced.

S240 with 42-in. (107-cm) Accel Deep™ Mower Deck

48A MulchControl handle

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 closed (shown on Z300 42A mower deck)

MulchControl baffle open (shown on Z300 42A 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 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.

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

When bagging with MulchControl on a 48A mower deck, 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.

Rear baffle (A) must be removed for bagging with MulchControl with 42A mower decks

When bagging with MulchControl on a 42A mower deck, the cut-and-throw rear bagger can be used with the MulchControl blades. However, the rear MulchControl baffle (A) needs to be removed to install the bagger chute. The baffle is held in place with two carriage bolts. To return to mulching, the chute needs to be removed and the baffle replaced.

MulchControl compatibility

Each MulchControl system is an optional field-installed attachment and includes everything needed for handle actuation: baffles, handle, and mulch blades.
