Compact excavators are powerful digging machines that are used for grading, leveling, backfilling, trenching, and general dozer work. These machines are so versatile you can do just about any type of construction work with them – from using a hammer to break up concrete to digging holes for landscape work. The work equipment of an excavator is similar to a human arm, enabling an operator to maneuver the machine just like moving his/her own arm. In addition, replacing a bucket with various attachments enables a wider range of work, such as breaking rocks, lifting or grabbing an object. The blade at the foot of the excavator can doze soil and level the ground. Most machines have a 360 degrees rotating capability which allows enhanced spoil placement, superior visibility and the ability to work in the tightest of spaces.
The mini excavator is also frequently used in many other applications other than excavation such as a tilt rotator, breaker, a grapple or an auger. The tracked undercarriage gives the operator great flotation compared to wheeled machines and it is much easier to haul because of its light weight.
There are two distinct classes of compact excavators, conventional tail swing - units that have a rear counterweight that will extend beyond the tracks when the house rotates, and zero-tail swing - units with a house whose diameter stays within the width of the tracks through full rotation. Zero-tail swing units allow the operator to focus on digging and not watching where he or she is swinging.
Advantages of mini excavators:
- easily transportable
- the rubber tracks prevent them from damaging curbs and asphalt
- many have zero-tail-swing clearance, which allows them to turn within the stance of the machine instead of swinging wide beyond the tracks
- terrific stability, leave a light footprint and have plenty of flotation
- maneuver in tight spaces
- very light machines therefore not needing permits to work or special drive licenses
- operates easily
- uses a wide variety of attachments

E-mail us to ask our rubber track specialists any technical or support
questions you may have.
Our most frequently asked question is "How do I find my track size?" There are
several ways to find out which replacement track you need. First, check your
existing track to see if the size is stamped into the rubber. It is usually
very difficult to find the track size as it is common for the stamp to wear off
during normal use. If you can't find a track size stamped into the rubber then
you can take three simple measurements that will determine which replacement
track you need.
Measure the width of the track in millimeters.
Measure the distance from the center of one link to the center of the next link
(in millimeters). This is commonly known as the pitch of the track.
Count the number of links, or lugs all the way around the track
The measurement is read Width x Pitch x Links.
Another common question concerns tread pattern. When it comes to mini excavator
rubber tracks there are several different tread patterns. Some machines have
two or three options for the tread pattern. Tread patterns tend to change over
the years as improvements are discovered every year. Currently these are some
of the most common examples of tread patterns we stock:
