The new Cat 302.7 CR, 303 CR, and 303.5 CR hydraulic mini excavators introduce industry-first features for the 2.7- to 3.5-tonne class machines. Built on the Next Generation platform, each new model features exclusive stick steer, cruise control, operator adjustable settings, and tilt-up canopy or cab as standard.

Expanded use of common parts throughout the line plus their damage-resistant exterior construction help to reduce parts inventory investment and lower repair costs. Daily maintenance checks are quickly made from the ground level through side doors, while the tilt-up cab design offers easy access to components for servicing. Increased service intervals mean these excavators spend more time on the job and less time in the shop. Combined, these features lower total ownership costs up to 5% compared to previous models, according to Caterpillar.

At the same time, design enhancements for the new 302.7 CR, 303 CR, and 303.5 CR deliver up to 10% more performance in travel and trenching. Hydraulic system upgrades improve lifting performance and cycle times, while customizable operator settings improve efficiency.

The turbocharged Cat C1.1 Turbo engine powers the 302.7 CR and 303 CR models, while the Cat C1.7 anchors the powertrain for the 303.5 CR. Both engines meet U.S. EPA Tier 4 Final emissions standards and offer 23.6 hp net power. Standard auto idle and auto engine shutdown help to conserve fuel usage at the site.
