Controls
Reduce fatigue.


Controls

Low effort, ergonomic excavator-style joystick controls provide smooth modulation. Thumb rollers provide convenient, fingertip control of auxiliary functions, eliminating pedals on the floor.

One-Touch Low Idle
Located on the right hand joystick, this button reduces engine speed to low idle. This new feature will reduce fuel consumption and improve communication with ground crew.

Pattern Selector
The pattern selector switch, located in the cab, allows the operator to change from excavator to backhoe control pattern simply by pressing a button. This allows the operator to use the pattern they are most familiar with to get more done, faster.

Hydraulics
Load-sensing system matches power to demand.


Hydraulics

The 420E has a load-sensing, closed center hydraulic system,which closely matches power and flow to the demand needed by the implements. So whether you're in full trenching mode, or delicately digging around services, you are in control. In applications such as production trenching, speed is important and the system will match the flow needed to get the job done quickly and efficiently. The load-sensing hydraulic system also delivers:
  • A cooler hydraulic system
  • Better fuel efficiency
  • Quieter operation
  • Reduced wear on components
Cat XT-3 ES ToughGuard™ hoses combined with Cat couplings and O-ring face seal fittings provide a leak-free system. The 420E also features new flow-sharing hydraulic valves, ensuring proportional flow of oil to all hydraulic cylinders, providing greater control and improving multi-function performance.

Ride Control
Delivers even greater operator comfort.


Ride Control

The optional Ride Control System smoothes the ride in all conditions, including load and carry, highway roading, or simply moving around the job site. It reduces machine loping, providing a smooth and stable ride for increased operator comfort and reduced operator fatigue. The Ride Control option improves material retention in the loader bucket for increased productivity and a cleaner job site. The system is easily engaged by a switch on the front console. The Ride Control switch has three positions, ON, OFF and AUTOMATIC. In the automatic position, the Ride Control engages automatically as the travel speed increases. At low speed, the system disengages for loading, grading or finishing applications.

Power Train
Built for performance, power, reliability and fuel efficiency.


Power Train

Cat Engine
The 420E features the Cat® C4.4 DIT (Direct Injection Turbocharged) engine with ACERT® technology and meets all U.S EPA Tier 3/EU Stage IIIa emissions requirements. The increased horsepower and torque rise deliver improved loading and roading performance.
  • Electronic engine control provides precise fuel metering for optimized power, response and fuel efficiency.
  • The water separator service indicator ensures the operator is alerted when service is necessary.
  • Dry-type axial seal air cleaner with automatic, integrated dust ejection system for more efficient pre-separation. Both air cleaner and precleaner functions are incorporated into a single unit mounted under the hood.

Transmission
The Cat standard power shuttle transmission provides four speeds forward and reverse. Hydraulically shifted clutches allow on-the-go direction and travel speed shifts. The optional auto-shift transmission matches gears with grade and load conditions. Top gear is selected with the twist grip control on the steering wheel.
  • Hydraulic proportional control valves smooth speed and directional shifts.
  • Transmission Kick-Down Switch/Neutralizer allows the operator to downshift through the gears to first.
  • Four Wheel Drive (4WD) option improves mobility and loader performance in poor underfoot and can be activated on-the-go.
  • Maximum roading speed of 40 km/h (25 mph) for faster travel between job sites.
  • Cat Rear Axles are designed specifically for demanding backhoe loader applications. Axles feature outboard planetary gear sets for easy serviceability and brake design improvements for longer service life.

Brake Mode Selector
The brake mode selector switch has three positions: two wheel drive, two wheel drive with all wheel braking and four wheel drive. Two wheel drive with all wheel braking provides better tire life while roading and engages the front axle when brakes are applied for improved braking performance.

Loader
Choice of loader linkage to meet your needs.


Loader

Caterpillar offers a choice of single tilt or integrated toolcarrier (IT) loader linkage to suit your application requirements. The IT loader controls provide single lever proportional control and fine modulation of the hydraulic work tools. A thumb roller operates auxiliary hydraulic functions such as the multi purpose bucket on the IT machines.

Single Tilt
The standard single tilt loader linkage features strong lift and breakout forces for solid performance in backfilling and truck loading applications.

Integrated Toolcarrier
The optional integrated toolcarrier (IT) loader linkage provides higher breakout forces, as well as parallel lift, for efficient loading and material handling. Integrated toolcarriers are highly versatile and can use a wide range of Cat Work Tools for a variety of applications.

Return-to-Dig
The return-to-dig system reduces loading cycle times by bringing the loader bucket back to the dig position with an easy pull of the lever. By the time the loader bucket is at ground level, the bucket is angled correctly for the next load or cut.

Backhoe
Boom and stick designed for high performance and easy service.


Backhoe

The E-Series backhoe delivers industry-leading digging forces. Serrated edges on the stick provide improved material clamping for clearing and demolition applications. The single pin bucket linkage contributes to best-in-class rotation of 205 degrees for all applications.

E-Stick Design
The optional extendible stick (E-stick) increases reach and dig depth by approximately 1.2 meters (4 feet). The new design delivers increased life and easy in-field adjustment with common hand tools.

Curved Boom
The excavator-style boom is built for optimum performance and durability. 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.
