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.

Features may include:

ALL DAY COMFORT
  • 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.
EASY TO OPERATE
  • 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.
STICK STEER TRAVEL MODE
  • 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!
BIG PERFORMANCE IN A COMPACT DESIGN
  • Strong lift and dig performance helps you get the job done faster. The compact radius design and retractable undercarriage let you access and work in the tightest areas. Dozer float allows for easy clean up.
SAFETY ON THE JOB SITE
  • 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.
