21.5-hp (16.0-kW) V-twin engine
The tractor is powered by a John Deere iTorque power system, a combination of engine features and an exclusive hood design that provides superior lugging ability, even cooling, and durability.
Key engine features include:
A flywheel alternator provides plenty of capacity to quickly recharge the battery and power electrical equipment, such as lights or a sprayer:
Fuel tank
Electronic fuel gauge
Large fuel tank and convenient fuel gauge minimize the number of stops for fuel and chance of running out of fuel:
X350 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:
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:
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:
Large discharge opening is both high and wide to handle more material:
Accel Deep 42A Mower Deck
The flat-top shape of the deck stamping is optimal for keeping itself and the operator clean:
Cleaning a mower deck, both top and bottom, is one of the most frequent maintenance activities:
Mower wash port
Mower wash port with hose connector
A wash port is provided to make cleaning the underside of the mower deck easy.
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:
Mower wheels are double captured:
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.
Rear MulchControl baffle (A) that must be removed for bagging
Rear MulchControl baffle removed to allow 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:
X350 with optional rear bagger
Two-piece chute (ordered separately)
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:
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:
Mulching blades are included with the optional MulchControl system. They can be used for mulching, side discharging, and bagging in most conditions.

| Side discharge, mulching, and bagging | Mulching blade (shipped with MulchControl) |
Power steering cylinder
Tilt steering lever (X390 and X394 only)
Hydraulic power steering is standard equipment:
Hydraulic lift
The hydraulic lift control lever is positioned on the dash near the steering wheel for quick, easy, and precise fingertip control of equipment. Implement float, which allows an implement to follow the ground contour, is built into the lift linkage.
Lever-action MulchControl lever (shown on 48A mower deck)
Electric one-touch MulchControl switch
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:
MulchControl baffle open (shown on Z300 48A mower deck)
MulchControl baffle closed (shown on Z300 48A mower deck)
MulchControl is an innovative, simple design that is easy to use and maintain:
MulchControl is well-suited to the following mowing situations:
MulchControl puts the operator in control of the clippings.
Electric one-touch MulchControl systems shift the MulchControl baffle using an electric actuator that is operated by a dash-mounted switch.
Electric one-touch MulchControl switcht
Electric one-touch MulchControl actuator (shown on 54A mower deck)
Operators can convert between modes without interrupting the mowing process, making it possible to change between modes:
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 bagging with MulchControl on a 48A or 54A 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.
Each MulchControl system is an optional field-installed attachment and includes everything needed: baffles, mulch blades, a handle (lever action attachments) or an actuator, wiring, and switches (electric one-touch attachments).

44-in. (112-cm) Front Blade, electric lift, angling and tire chains on an X350 Tractor
44-in. (112-cm) Snow Blower, weather enclosure and tire chains on an X350 Tractor
An advantage of lawn tractors is their ability to use equipment for snow removal. Lawn tractor owners can add a John Deere snow blower or front blade to make quick work of moving snow whenever the need arises. Weather enclosure and tire-chain attachments add comfort and performance.
Equipment available for snow removal includes:
Kanzaki® K46 transaxle (X330, X350, X354) Kansaki K57 transaxle (X370)
Kanzaki K58 transaxle (X380, X384, X390, X394)
The Tuff Torq® hydrostatic transaxle encloses the hydrostatic pump and motor rotator groups in the same housing with the differential and axle housings. This design is very efficient and reduces the number of sealing surfaces to minimize the potential for leakage.
Combined with the foot controls, the hydrostatic transmission functions similarly to that of an automatic transmission in an automobile, so the term automatic is often used to describe it:
Freewheeling valve
When it's inconvenient to start the tractor, a freewheeling valve releases the transmission so the tractor can be pushed a short distance. The freewheeling valve control is conveniently located on the tractor’s rear hitch plate.
