Caterpillar added a new 15-ft. model 440 center-privot backhoe with 25% more backhoe lifting capacity to complement the 430F2 at the same time it introduced the updated 17-ft. Cat 450. Both models get seat-mounted electrohydraulic controls and significant increases in lifting capacity.
The new 450 offers 15% more backhoe lifting capacity and 14% more loader capacity than the 450F and introduces a new cab. Breakout forces have also significantly increased on both the 440 and 450, and electronic control allows the single-tilt loader arms to provide full-time parallel lift.
Power for comes from the Cat C4.4 ACERT engine that meets Tier 4 Final emissions standards using a service-free SCR technology (Caterpillar had been selling the 450 F using flex credits). Standard autoshift transmission features a sixth gear to improve roading performance, and optional lock-up torque converter.
Seat-mounted controls rotate with the operator when working with the loader or the backhoe, significantly increasing legroom at the rear of the cab. Electrohydraulics allow the operator to sit at a 45-degree angle to the rear of the cab for increased operating comfort when loading trucks and clearing ditches. A new Dual Mode allows the operator to use the attachment behind them to help reposition the machine without swiveling around. New programmable auto kickouts quickly establish upper and lower arm positioning for repetitive work like loading trucks. And return-to-dig limits can be set for efficient loader work.
