Cat 450F backhoe loader is a four-wheel-drive unit powered by a Cat C4.4 diesel meeting Tier 4-Interim standards, available in the second quarter of 2013. Gross power is increased 5 percent, and torque 30 percent, to 396 lb.-ft. An Automatic Engine Speed Control feature reduces engine speed if hydraulic functions are idle, contributing to increased fuel efficiency and reduced sound levels. A closed-center, load-sensing hydraulic system uses an variable-flow main pump that is now electronically controlled to provide enhanced power management and response. The loader is self-leveling and incorporates a return-to-dig feature.
The 450F operator’s station features an air-suspension seat, ergonomically designed joystick controls, redesigned gauge cluster that simplifies navigating through system information and control settings, and an available Machine Security System that utilizes a programmable key to deter theft, vandalism and unauthorized usage. Standard equipment includes a 5F/3R AutoShift transmission, with four wheel drive and the Cat Ride Control system, which smooths the machine’s ride.
Optional equipment for the 450F includes an extendible stick, deluxe cab with air conditioning, cold-weather package, third-function loader valve, six-function backhoe valve, auxiliary hydraulic lines, and the Cat Product Link telematics system.
