Caterpillar 420D Loader Backhoe
The 420D has pilot stabilizer controls, pilot loader controls, high rotation backhoe linkage, and a hydraulic pump that delivers fluid at a rate of 43 gallons (163 L) per minute (GPM) at a system pressure of 3,300 pounds per square inch (PSI) (22,753 kPa).
The 420D was manufactured in the USA, with a BLN or FDP serial number prefix, and in England, with a BKC or BMC prefix.
The BKC unit has a single tilt loader; the BMC is an integrated tool carrier loader.
In 2002 Caterpillar released a new 420D in the USA, with a MBH prefix. It has a redesigned front axle, and low-leak backhoe hydraulics. Cat also modified its fuel tank filler neck, single tilt linkage roll back, and operator features.
In 2004 Cat introduced the 420D Series II in England only, beginning with BKC00920 and BMC01060. It included a redesigned front axle and a number of miscellaneous feature changes to reduce production costs.
Production of FDP and MBH ended in 2004; BKC and BMC ended in 2005.
The Caterpillar 420D was replaced by the Caterpillar 420E.
Based on data from the sales database of Ritchie Bros. Auctioneers, it is estimated that more than 34,300 Caterpillar 420D loader backhoes have been produced.
