The Cat 440 and 450 center pivot backhoe loaders provide industry-leading lifting performance, high breakout forces, and improved operating comfort and ergonomics. The 440 boasts a 25% backhoe lifting improvement over the 430F2 and redesigned single tilt loader arms, providing parallel lift and versatility in a multitude of applications. The 450 offers 15% higher backhoe lifting capacity than the 450F and introduces an all-new cab for increased operator comfort.

Lift and tilt breakout forces have also significantly increased on both the 440 and 450 to improve machine productivity. A more balanced weight design and longer backhoe stabilizer legs improve operating stability. The new stabilizer systems can be equipped with available guards to prevent damage to the cylinder rod, and optional leg plate guards prevent material build-up on the underside of the stabilizer leg.

The powertrains for both models are anchored by the Cat C4.4 ACERT engine that meets Tier 4 Final emissions standards using a service-free selective catalytic reduction solution. The 440 and 450 optimize engine speed and pump displacement for excellent performance. The standard Autoshift transmission features a sixth gear for improved roading performance, and optional Lock Up Torque converter for improved torque and efficiency on grades. New spring-applied hydraulically released brakes provide simplified operation of the parking brake.
