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

Category:

ALL DAY COMFORT

  • Choose either a canopy (not available in some regions) or a sealed and pressurized cab 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 machine information in a clear and easy to read format.

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 help you get the job done faster. The compact radius design allows you to access and work in the tightest areas. Dozer float enables easy clean up. An angle blade is also an option for finished grading and easier backfilling applications.

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, a fluorescent retractable seat belt and seat belt reminder are just a few of the safety features we’ve built into the machine.

SIMPLE SERVICE FOR LESS DOWNTIME

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

LOWER OPERATING COSTS

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

UNMATCHED DEALER SUPPORT

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