Caterpillar 307 E2 Mini Excavator Specs

Category: Mini Excavators ➔
Manufacturer: Caterpillar ➔
Model: 307 E2 ➔

The Caterpillar 307E2 is a compact mini excavator designed for utility, landscaping, and general construction work. It is part of Caterpillar's 7-ton class and is commonly used where maneuverability and transportability are important. The 307E2 features a reduced tail swing design, hydraulic performance suited to digging, trenching, and lifting tasks, and a cab or canopy configuration depending on market and specification. It is typically equipped with a diesel engine, auxiliary hydraulic capability, and undercarriage options for different ground conditions. The model is used in confined job sites where a larger excavator would be less practical.
