What is a Mini Excavator?

A mini excavator is compact digging machine with a weight capacity ranging up to 10 tons. Mini-excavators are popular with contractors, landscapers, and land owners for their ease of use, performance, and versatility in tight spaces. Mini-excavators are also easy to transport: even the largest units can be moved with a large pickup and gooseneck trailer.

What Jobs are good for Mini Excavators?

Mini-excavators reduce the need for post hole diggers, shovels, and wheel barrows, allowing you to get more work done in less time, and with a reduced risk of back and shoulder injury. From digging holes to trenching for electrical, gas, water, or sewer lines, to tearing down walls or old buildings, landscaping, and digging room for foundations, swimming pools, or ponds, a mini-excavator is the closest thing there is a hydraulic multi tool!
