446D^Non-Current

Joystick Controls

Optional pilot operated joystick controls add excavator technology and ease of operation to the 446D. Low effort controls are easy to use, reduce operator fatigue and increase efficiency.

Pattern Changer Valve

A standard pattern changer makes switching between backhoe and excavator control patterns as easy as moving a lever on the side of the machine.

Pilot Operated Stabilizer Controls

Provide low effort and fine modulation control. The stabilizer controls are within easy reach of the operator when operating the backhoe.

Pilot Control Pods

Located on the left and right sides, the controls can move fore and aft and three stops are available for ergonomically correct positioning.

Loader Linkage

Step aboard a Cat 446D Backhoe Loader and see for yourself, hit the job with more power, superior breakout forces and smooth easy-on-the-operator hydraulics. The loader features increased lift and breakout forces for powerful performance. Loader work tools enhance machine utilization and provide versatility. Standard autoshift transmission, self-leveling and a return-to-dig system make operation easy and allow fast cycle times.

High Rotation Backhoe Linkage

The new 446D backhoe linkage provides superior rotation and eliminates the need to change pin position when moving from loading trucks to vertical wall trenching.

Backhoe Boom

The excavator-style boom features box section fabrication with internal stiffeners for superior strength, balance and weight distribution. The curved design provides additional clearance over obstacles while digging a trench or truck loading. The narrow boom enhances the viewing area to the bucket and trench throughout the entire operating range.

Dig Forces

The 446D boom, stick and bucket dig forces have increased about ten percent overall.

Extendible Stick

Dig deeper and reach further with the Caterpillar extendible stick. This optional backhoe attachment replaces the standard stick and increases reach and dig depth by approximately 1.2 meters (4 feet). The extendible stick uses eight self-lubricated, non-metallic wear pads which can be shimmed or replaced.

Optional Quick Coupler

For greater machine versatility, the optional hydraulic quick coupler is available from your Cat dealer and allows the operator to choose from a wide range of tools.

Caterpillar 3114 DIT Engine

The Cat 3114 DIT (Direct Injection Turbocharged) engine is designed to meet demanding 446D requirements. High-tech components reduce sound levels and improve fuel efficiency. Cast oil-pan provides high impact resistance and added block strength. Spin-on filters allow for quick, clean maintenance.

Power Train

Designed for strength, performance, and versatility. Easy, on-the-go shifting between all gears, two- and all-wheel drive. A single lever controls both direction and speed for improved operator efficiency.

Front Axle

Large diameter, double-acting steering cylinder resists bending and is well protected.

Heavy-Duty Main Frame

Fully welded, one-piece frame absorbs stress and minimizes shock loads to the power train.

Brakes

Fully enclosed, hydraulic, multiple discs.

Caterpillar Autoshift Transmission

The 446D backhoe loader is fitted with an autoshift transmission as standard equipment. The autoshift function automatically matches gears with grade and load conditions.

Hydraulic System

The load sensing, variable flow hydraulic system senses work demand and adjusts flow and pressure to match. This allows full hydraulic forces at any engine speed for delicate jobs in tight areas.

Hydraulic Pump

Closed centered implement valves, with pressure compensation for reduced lever effort, signal hydraulic system requirements to a control valve located on the pump. This valve controls the pump to deliver the flow and pressure necessary to fulfill the implement demands.

XT-3™ ES hoses

Improved bend radius and abrasion resistance provide reliable long life in the toughest conditions. Made of four overlapping, insulated wire spiral wraps bonded together for durability, XT-3 ES (Enhanced Spiral) hoses exceed SAE certification standards. The hose routing protects them from work damage, and hose failure downtime is substantially reduced. XT-3 ES hoses combined with Caterpillar couplings and O-ring face seal fittings provide a leak-free system.

Clamps and Bushings

Metal clamps with rubber bushings are used at hose attachment points to eliminate metal-to-metal contact and increase wear life.

Operator Comfort

The 446D operator station incorporates years of cab design innovations to maximize operator productivity. The optional pilot operated controls allow more legroom and a spacious work environment.

ROPS Canopy

Includes air suspension vinyl seat, tilt steering wheel, pilot operated stabilizer controls with auto-up feature, 12-volt power supply, phone clip, left-side storage space with a lockable compartment, drink holders and floor mats.

Deluxe Cab

The ultimate in operator comfort, the deluxe cab includes all standard amenities plus a deluxe, nine-way adjustable air suspension seat; pilot operated stabilizer controls with individual auto-up feature; additional system monitoring including a voltmeter and service indicators for fuel water separator, engine air cleaner and hydraulic filters.

HVAC System

The heating, ventilation and air conditioning system main components are located near the floor. New ducting to the rear improves air circulation, increases defrost capabilities and provides exceptional air flow to the operator.

Tilt Wheel

The standard tilt steering wheel allows more space for ease of access and exiting the cab. The operator can choose the most comfortable steering position.

Air-Suspension Seat

Utilizes an air adjustment mechanism for a greater operating range and more comfortable ride. By pressing a button, the seat can be tailored to support differing body weights. Adjustable seat height accommodates all operators. The Deluxe cab seat also features an adjustable back support, lumbar support, seat cushion extension, seat cushion tilt as well as vertical and angle adjustable armrests.

Operator Controls

The Cat 446D backhoe loader provides smooth, precise control, and ease-of-operation.

Machine Controls

The 446D has two choices of backhoe controls available. You can choose mechanical backhoe controls in either the Ford or Dynahoe control pattern, or pilot controls that are switchable between backhoe and excavator patterns based on operator preference with the simple, included, pattern changer.

Ride Control System

Provides a smooth ride in all applications, reduces machine loping while roading and provides better material retention during load and carry operations while greatly increasing operator comfort. A nitrogen accumulator added to the loader lift circuit cushions the system and engages with the flip of a switch.

Rear Window

The redesigned rear window features a heavier hinge structure and positive latch mechanism to hold the window in the open position.

Fuel Tank

Large capacity tank located on the frame's left side is lockable and includes a replaceable, bolt-on step.

Tool and Battery Box

Spacious, convenient and secure tool storage location.

Finish Protected Components

All 446D Backhoe Loaders are assembled with components already topcoat painted or plated. This new process improves the appearance of the machine while enhancing the overall quality of each component, providing 100% protective coverage.

New Work Lights

New adjustable work lights are wider spread to the corners for improved night performance.

Stabilizer Guards

Now available from the factory for cylinder protection in all applications.
