The Caterpillar 420F backhoe, part of Cat's F Series backhoe range, which also includes the 416F and 430F, is a center-pivot machine that is powered by a Cat Tier IV Interim C4.4 engine.
For the F Series backhoes, Caterpillar kept some of its premium design features from the preceding E Series backhoe lineup, including:
A powerful, load-sensing, closed-center hydraulic system
The Caterpillarfour-speed power shuttle transmission for on-the-go directional and range shifting
An excavator-style boom for additionalclearance when digging over obstacles or loading trucks
An ergonomic, automotive-style operator's station that providessafety, comfort and convenience.
Performance Enhancements on the Cat 420F Backhoe
The 420F's electronically controlled Cat C4.4 engine usesa high-pressure common-rail fuel system for operating efficiency and is equipped with the Caterpillar NOx reduction system and a diesel particulate filter for emissions control. The Caterpillar 420F backhoe's net horsepoweris 93.Gross power is 101.9 horsepower.
The 420F sports an aggressive torque converter for improved performance when both loading androading. The 420F hasan electronic pump torque limiter for higher power management, as well as improvedhydraulic performance. Hydraulic refinement also includes more precisely tuned spools in the backhoe valve.
The Caterpillar 420F's operational maximumweight is 24,251 poundsand its fuel capacity is 43.6 gallons. The 420F's standard digging depth is 14.3 feet and the load at maximum lift is 7,237 pounds.
Sturdy and Easy to Service
The Cat 420F uses a composite fuel tank that resists rust and reduces condensation, and a hydraulic tank that incorporatesa suction strainer and a large, replaceable, cartridge-type filter. The hinged cooling pack improves service access, as do new engine side panels that require no tools for removal.
On the Cat 420F, the battery compartment was moved to the nose of the tractor, leavingspace for a right-hand storage box and a remote jump-start feature provides easy access. One-piece counterweights improved machine balance, and a new double-clevis swing casting design addeddurability.
