Mini excavators are great machines for a wide variety of tasks, everything from excavating for underground utility installations to moving decorative rocks in a patio project to breaking up concrete in a demo job. Their compact size allows most of them to be transported without a CDL and work in areas where larger equipment simply cannot fit. The mini excavator category includes models ranging from 0 to 8 metric tons, with the 3- to 4-metric-ton range being the most popular. However, larger minis are gaining interest.
When sizing up a new machine, it’s important to consider current and future applications. Since mini excavators are now being used for a broader range of jobs, buyers should ensure that their machines are the appropriate size and deliver enough power to operate the attachments they need to use — plus a little extra muscle for future endeavors. I highly suggest you read these excellent articles from our archives on how to buy, rent and maintain a mini excavator. Then, I’ve gathered a bunch of options to get your mind thinking about a specific model. Enjoy!
