Benefits & Features
Pilot Operated Joystick Controls
Joystick Controls
Standard excavator-style, joysticks provide smooth modulation and are ergonomically designed for low effort control and operator comfort. As a result of this control design, legroom is increased and the rearward viewing area is greater.
Standard Pattern Changer Valve
The hydraulic excavator control pattern is standard and switching between backhoe and excavator control patterns with the standard pattern changer valve is as easy as loosening and moving a bolt on the side of the machine.
Pilot Operated Stabilizer Controls
These provide low effort and fine modulation control. The standard stabilizer controls are within easy reach on the operator's side 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 Performance
Loader Linkage
The standard single-tilt loader features increased lift and breakout forces. The optional integrated toolcarrier loader provides even higher forces, as well as parallel lift for efficient loading and material handling. A return-to-dig system makes operation easy and improves cycle times.
Quick Coupler
Provides versatility and allows quick connection to selected work tools for the Cat family of integrated toolcarriers. Most work tools can be changed in less than 30 seconds, from the comfort of the operator station.
Disconnects
Flat face hydraulic hose quick disconnect fittings with a connect-under-pressure feature improve the connection of hydraulic work tools.
IT Loader Controls
The 420D IT has a new, standard single lever, pilot-operated loader control for proportional control and fine modulation of the hydraulic work tools. A thumb roller control on top operates auxiliary hydraulic functions such as the clam bucket and two buttons control hydraulic broom angle.
Reverse Signal System
Pump control changes improve power management between the loader hydraulic system and machine rimpull for faster truck loading. The reverse signal system provides priority to backhoe hydraulics to maximize hydraulic horsepower.
Backhoe Performance
High Rotation Backhoe Linkage
Single pin bucket linkage contributes to best-in-class rotation of 205 degrees for all applications, eliminating 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 better 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.
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. Durable wear pad materials increase wear life in all conditions.
New Cat Cushion Swing System
The new, standard Cat Cushion Swing System smooths the backhoe swing function when returning to the trench.
New Backhoe Swing Casting
Improved with replaceable bushings for durability and serviceability.
Buckets and Couplers
Bucket Line
Cat's expansive bucket line includes rock and coral bucket designs. All D-Series buckets are painted black and carry the Cat logo.
Bucket Characteristics
The side profile has a scalloped edge, similar to an excavator bucket, for exceptional fill factor characteristics and secure clamping ability.
New DRS 230 (Diagonal Retention System)
New DRS 230 with wide adapters provides maximum strength and improved wear characteristics. Heavy-duty bucket teeth are attached with diagonal pins rather than horizontal pins for easy exchange. The adapters are stronger as a result of this improved diagonal pinning and additional wear material on the bucket teeth increases durability.
Quick Couplers
Allow for quick attachment of buckets and other work tools. The D-Series High Rotation pin grabber design and a C-Series compatible pin grabber allow buckets to be changed without removing the bucket pins. Other manufacturers' buckets can be coupled with a pin puller coupler, one for Case and D-Series buckets or one for John Deere and D-Series buckets. D-Series quick couplers are painted black for easy identification.
Lift Eye
An integral lifting eye is a standard feature of the bucket linkage.

Direct Injection Fuel System
Individual unit fuel injectors deliver efficient and accurate fuel metering, reduced emissions, reliable power, high torque rise and responsive performance. A new water separator service indicator ensures the operator is reminded when service is necessary.
Air Cleaner
A new, dry-type, axial seal air cleaner with automatic, integrated dust ejection system provides more efficient pre-separation. The two-stage air filter incorporates both air cleaner and precleaner functions into a single unit mounted under the hood.
Transmission
The Caterpillar Power Shuttle transmission provides four speeds forward and reverse. Full synchromesh gears and hydraulically shifted forward and reverse shuttle clutches allow direction and travel speed to be changed on-the-go. A neutral start provision prevents starting while the shuttle is engaged.
Automatic Shift Transmission
The optional Auto-Shift transmission automatically matches gears with grade and load conditions. Manual mode gives full gear selection to the operator for operation as a Power Shift transmission.
Kick-down Switch/Transmission Neutralizer
Located on the loader lever, the kick-down switch on Auto-Shift machines allows the operator to downshift through the gears to first. When this switch is depressed for more than one second, it serves as the transmission neutralizer to maintain engine and hydraulic speed when dumping into trucks.
Transmission Neutralizer
Standard on Power Shuttle machines, the hand-operated power disconnect provides easy, on-the-go shifting and full engine rpm for faster cycle times.
Ride Control Option
Offers a smooth ride in all conditions and reduces machine loping while roading. It also provides better material retention during load and carry operations while greatly increasing operator comfort. The system engages with the flip of a switch.
New Caterpillar Front Axles
New, Cat heavy-duty front axles are developed specifically for demanding backhoe loader applications.
Rear Axles and New Brakes
Heavy-duty rear axle with self-adjusting inboard brakes, differential lock and final drives. New Kevlar brake discs extend service life, provide quieter braking and decrease stopping distance.
Two Wheel Drive
New tapered roller bearings improve kingpin alignment and more wear resistance to extend the life of the front axle and tires.
All Wheel Drive (AWD) Option
Heavy-duty front drive axle can be engaged at any time by activating the switch on the front console. The switch can be activated while the machine is stopped or moving, with or without load. AWD features outboard planetary gear final drives and improves mobility and loader performance in poor traction conditions.
Brake Mode Selector
The brake mode selector switch has three positions: two wheel drive, two wheel drive with all wheel braking and all wheel drive. Center position provides two wheel drive for better tire life while roading and engages the front axle when brakes are applied for improved braking performance.

The Deluxe cab seat also has an adjustable back support, lumbar support, seat cushion extension, seat cushion tilt, as well as vertical and angle adjusting armrests.
Operator Controls
The controls of the 420D have been carefully laid out to create a user-friendly environment. Switches, boom lock and pilot operated stabilizer controls are located in the side console, within easy reach of the operator. White-faced gauges are easy to read and the low effort pilot controls reduce operator fatigue and help boost overall productivity.
Ride Control System
Provides a smoother ride in all applications, reduces machine loping while roading and provides better material retention during load and carry operations while 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 rear window features a heavy-duty hinge structure and positive latch mechanism to hold the window in the open position.
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.
Dual Setting Torque Limiter
The variable displacement pump provides better performance in both backhoe and loader operations through a dual setting torque limiter. It automatically optimizes power to the hydraulic system during backhoe operations and manages the power balance between the loader hydraulic circuit and the drive train during front loader operations.
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.
