The Caterpillar 305 CR is a mini excavator in the 5-tonne class. It is aimed at utility trenching, landscaping and residential work where a larger excavator would not fit the site.
Caterpillar's current Tier 4 / Stage V listing gives a net power of 45 hp (33.6 kW) and a maximum dig depth of 144.5 in (3,670 mm). The maximum operating weight is 12,688 lb with cab, and the minimum is 11,234 lb, so the configuration decides the weight.
Older 305 CR variants, including Tier 3 and 305E2 CR models, are listed with lower power and different weights. Check the model year and emissions tier before comparing with another brand.
