• 48-in. Accel Deep™ mower deck

• Powered by 22 hp (16.4 kW) iTorque™ Power System

• 4 year/300 hour bumper-to-bumper warranty

Features may include:

The tractor is powered by a John Deere iTorque™ power system, a combination of engine features and an exclusive hood design that provide superior lugging ability, even cooling, and durability.

A 22-hp (16.4-kW) V-twin engine provides plenty of power and torque to handle tough mulching, mowing, and bagging conditions.

• 22 hp (16.4 kW)

• Large 726-cc displacement

• V-twin air-cooled design that provides smooth, quiet power

Quality features include:

• Cast-iron cylinder liners

• Overhead valves

• Full-pressure lubrication

• Replaceable oil filter

Dual-stage air cleaner V-twin design:

• Excellent power and performance

• Easy starts

• Smooth operation

FLYWHEEL ALTERNATOR

A flywheel alternator provides plenty of capacity to quickly recharge the battery and power electrical equipment, such as lights or a sprayer:

• 15-amp capacity

• Regulated to keep the battery at full charge without risk of overcharging

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):

• Uncut circle radius is reduced from 21 in. (53 cm) for a two-wheel steer X380 to only 9 in. (23 cm), eliminating or greatly reducing the need to back up when trimming around trees, shrubs, etc.

• Interference from the mower and tractor wheels is eliminated because they are several inches away from the object being trimmed around.

• 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 4-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.
