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, 3.3-U.S. GAL. (12.5-L) CAPACITY

Large fuel tank and convenient fuel gauge minimize the number of stops for fuel and chance of running out of fuel:

• Fuel tank has a large, 3.3-U.S. gal. (12.5-L) capacity for more hours of operation between refills.
• Large, 3-in. (7.6-cm) diameter fuel tank filler opening makes adding fuel easy.
• Located on the left fender
• Helps eliminate spillage
• Electronic fuel gauge on the dash display allows the operator to easily monitor the amount of fuel in the tank.

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 lever-action or electric one-touch MulchControl™ system for 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 7-bu (247-L) two-bag cut-and-throw material collection system
• For use on X330, X350, X354, and X370 Tractors

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 - 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

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.

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 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.

MOWER BLADES

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.

VERSATILITY - EASY TO CHANGE BETWEEN SIDE DISCHARGE, MULCH, AND BAGGING MODES

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.

7-BU (247-L) REAR BAGGER

An optional 7-bu (247-L) cut-and-throw rear bagger material collection system (MCS) is available for use with the 42-in. (107-cm) Accel Deep Mower. It provides an efficient means of collecting grass clippings and leaves.

The hopper design provides modern styling, great bagging performance, cleaner operation, and easy-to-empty bags:

• 7-bu (247-L) capacity
• Easy-to-attach lower chute (ordered separately)
• Air exhaust duct
• Convenient spring-latch
• Airflow fill indicator
• Quik-Tatch mounting
• Sealed hopper top

Four-wheel steering versus two-wheel steering

Four-wheel steer maneuverability

NOTE: In the schematic above, the solid line refers to a four-wheel steer tractor, and the hashed line refers to a two-wheel steer tractor.

Four-wheel steering provides very significant maneuverability and trimming advantages over that of two-wheel-steering-equipped tractors.

For example, with the X384 Select Series™ Tractor equipped with a 48-in. (122-cm) Accel Deep™ Mower (the following numbers correspond to the schematic above):

1. Uncut circle radius is reduced from 21 in. (53 cm) for a two-wheel steer X380 to only 9 in. (23 cm) for an X384, eliminating or greatly reducing the need to back up when trimming around trees, shrubs, etc.
2. Interference from the mower and tractor wheels is eliminated because they are several inches away from the object being trimmed around.
3. Outside turning circle is reduced, reducing the time spent turning and increasing mowing efficiency.

Also, trimming inside curves around flower beds or other landscaping can be done more completely with a four-wheel steer tractor.

DESIGNED FOR TIGHT TURNS

The four-wheel steering system is designed for tight turns, leading to greater mowing efficiency:

• Caster, camber, and kingpin angles are optimized to reduce effort, especially when going from straight ahead into a turn.
• Steering geometry has been designed with the use of 3-D modeling, so all four tires are working together.
• Sealed ball bearings are used on the torque shaft and the rear spindles to reduce friction.
• Small scrub radius, less than 1 in. (2.5 cm) in the rear, reduces scuffing and bump-steer.

DESIGNED FOR EASY STEERING

Sealed ball bearings are used at critical all-wheel-steer joints for reduced friction, longer life, and less maintenance.

Easy steering is important for an enjoyable mowing experience:

• Larger, 14-in. (35.6-cm) diameter steering wheel gives improved leverage for easier turns.
• Larger sector gear gives improved (higher) steering ratio.
• A higher ratio equals lower steering effort.
• Dual drag links help equalize steering loads and greatly reduce steering error.
• Ball-joints on both ends of the steering tie rods reduce wear to maintain accurate steering.
• Long steering arms improve the mechanical advantage of the steering system through the full range of motion.
• The steering shaft rotates on a sealed ball bearing at its lower end, near the pinion gear, to reduce steering effort and provide a smooth feel for the life of the tractor.
• The sector gear pivots on a shaft rather than a bushing to ensure proper gear mesh and eliminate binding.
• Pivoting of the upper and lower ends of the sector gear shaft on sealed ball bearings reduces steering effort and provides a smooth feel for the life of the tractor.
• Greaseable front steering spindles reduce friction and improve wear over time.
