History and service record of 302.7 CR, 303 CR, and 303.5 CR

Launch in 2021. Caterpillar introduced the 302.7 CR, 303 CR and 303.5 CR in June 2021 as the next additions to its Next Generation mini excavator line, with what it called industry-first features for the 2.7- to 3.5-tonne class, aimed at operating efficiency, servicing ease and operator comfort. Cat introduces 2.7 to 3.5 tonne mini-hydraulic excavators, Highways Today, 16 June 2021.
What they replaced. Trade press reported that the three models replace older designs: the 20-year-old 302.7D, the 15-year-old 303E and the 10-year-old 303.5E2. Caterpillar takes 2.7- to 3.5-tonne mini-excavators to the Next-gen level, For Construction Pros.
Engines. The 302.7 CR and 303 CR use the Cat C1.1 Turbo engine, while the larger 303.5 CR uses the Cat C1.7. Cat intros new mini hydraulic excavators, Landscape Management.
Claimed gain. Caterpillar said its design enhancements deliver up to 10 percent more performance in travel and trenching on the three models. Cat intros new mini hydraulic excavators, Landscape Management.
2025 software update. At Utility Expo 2025 Caterpillar announced a software update for the 303.5 that gives a faster transient speed than the earlier Next Generation models, so the machine repositions faster and spends less time not working. Closer Look: Cat upgrades Next-Gen 303.5, 305 CR, 308 CR mini excavators, Equipment World.
