Mini Excavators for Precision Digging and Demolition
Otherwise known as a “mini digger” or "compact excavator", mini excavators have a standard boom and bucket design along with a small frame that excels in performing small-to-medium jobs in tight, confined spaces. A mini excavator is primarily used for digging holes and ditches, and for transporting materials, but with the right attachments, mini excavators can also trench, remove stumps, mulch materials, demolish small structures, plow snow, help repair utility lines, and a whole lot more.
My Little Salesman lists mini excavators for sale that can still get the job done even in adverse conditions such as steep slopes, muddy terrain and little working room. Whether you need a tracked or wheeled excavator for indoor or outdoor operations, you can find the right mini digger (and all of the necessary attachments) right here!
Choosing the Right Mini Excavator
Both new and used mini excavators can dig, on average, about 10 feet into the ground. This is ideal for utility work, residential construction, and any site where a smaller bucket is needed for precision digging. A mini excavator becomes much less effective, however, on larger construction sites and wide open spaces in general, though they can still be of limited aide.
Specs to consider:
- Weight – An excavator has to weigh less than 40 tons to be considered a mini excavator.
- Lighter excavators have less of a footprint and do not disturb the soil as much as larger excavators.
- Lighter excavators will be able to easily fit in small areas like urban construction sites and warehouses.
- Dig Depth – Although 10 feet is the norm, denser soils and materials will lessen the dig depth and may require additional attachments.
- A mini excavator can only dig through mud using a larger-than-normal bucket, which can sometimes take away its precision advantage.
- Dump Height – Most mini diggers can reach 13 feet at the most when dumping.
- Bucket Capacity – The amount of material or soil the bucket can hold.
- Operating Weight – How much weight the boom arm can take.
Inspecting Used Mini Excavators for Sale
Be sure to check for the following on mini excavators before buying:
- Exterior Damage – Cracks, bends and dents are bad in general. Cracks within the boom and stick or between the stick and the bucket are automatic deal breakers. Large cracks and bends could indicate severe structural damage, especially on the undercarriage.
- Leaks – Check out the hoses, lines, and cylinders within the hydraulic pump compartment to make sure there are no leaks. Leaks in the slew ring or swing bearing could loosen connections and make the mini digger less accurate. While not a deal breaker, all leaks will absolutely need to be repaired before the mini excavator can be safely used.
- Scalloping – Check the teeth of the mini digger bucket to make sure they have not bent out of shape. A scalloped bucket may not need to be replaced right away, but it will not be able to dig nearly as well, and it will fail eventually.
