Overview

Mini Excavators Inspired by Our Customers

The Cat® 305 CR Mini Excavator delivers power and performance in a compact size to help you work in a wide range of applications.

Benefits

4 Industry First Features

Cat Exclusives in a Mini Excavator

Up to 10% Lower Total Ownership Costs

with extended service intervals, lower repair costs and easy service access

Up to 20% More Performance

in lifting, digging and multi-function capability

Features At A Glance

Choose either a canopy or a sealed and pressurized cab which can be equipped with air conditioning, adjustable wrist rests, and a suspension seat to help keep you working comfortably all day long.

Controls are easy to use and the intuitive Next Generation LCD monitor provides easy to read machine information. An advanced touchscreen monitor can also be equipped as an upgrade option.

Moving around the job site is even easier with the Cat Stick Steer option. Easily switch from traditional travel controls with levers and pedals to joystick controls to move the machine and to operate the blade. The benefit of less effort and improved control is in your hands!

Strong lift and dig performance helps you get the job done faster. The compact radius design lets you access and work in the tightest areas. Dig-to-blade and dozer blade float allows for easy clean up. An angle blade is also an option for finished grading and easier backfilling applications.

Your safety is our top priority. The Cat mini excavator is designed to help keep you safe on the job. Courtesy work lights and a fluorescent retractable seat belt with optional seat belt reminder system are just a couple of the safety features we’ve built into the machine.

Maintenance is quick and easy on the Cat mini excavator. Routine check points are easy to access at ground level through the side doors.

Equipped with features such as auto idle, auto engine shutdown, and efficient hydraulics with a variable displacement pump, the Cat mini excavator was designed with reducing your operating costs in mind.

Your Cat dealer is here to help you reach your business goals. From providing equipment solutions to operator training to service needs and beyond, your Cat dealer is ready to help.
