Loader Performance

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.

Backhoe Performance
Superior bucket rotation and forces, an excavator-style backhoe boom and an optional extendible stick combine for high productivity levels.


Backhoe Performance

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.

Power Train

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.

Hydraulics
Our closed-center, variable displacement, load-sensing hydraulic system provides high power where you need it, when you need it.


Hydraulics

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 Station
The 446D operator environment is ergonomically designed to create a comfortable work area with easy-to-use machine controls that reduce operator fatigue, increase efficiency and productivity.


Operator Station

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

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
