What Size Mini Excavator Do I Need?

How to Choose a Mini Excavator

Excavators are versatile machines that come in many sizes and configurations. They are used for digging footings, land clearing, underground utilities, construction, agriculture and much more. With so many options, it can be difficult to know where to begin.

 

What attachments do you need?

Important Questions

  • What is the work that needs to be done?
  • What is the size, shape and scope of the job site?
  • What work tools/attachments would make your machine more productive? (Rippers for stump removal, grading bucket for digging footings, compactor wheel for laying pipe…)
  • How will you transport the excavator?

Once you know these answers, you can begin specifying the machine. It must be large enough to get the job done, but bigger isn’t necessarily better. How tight is the jobsite? Are there buildings close to one another?

This is when many of our customers decide to consult with a machine sales representative. They are versed in machine application and familiar with the territory. They can show options for new, used, and rental. They can even recommend subcontractors if needed.

The new High Definition Hydraulic (HDH) System, redesigned operator station and enhanced digital control panel specially designed for Cat Mini Excavators – COMPASS (Complete, Operation, Maintenance, Performance, and Security System) – are all standard features that improve performance and increase value.

 

309 CR

6-10 Ton Excavators

To develop the Next Generation of Cat Mini Excavators, we focused on the one most important component - you.

It includes multiple industry-first features:

  • Stick steer travel control
  • Cruise control
  • Full color LCD monitor with Bluetooth
  • High flow hydraulics on 309 model

 


 

Excavator Undercarriage Options

Job site environments vary greatly – manicured turf, rocky hills, paved surfaces. When possible, you should match the undercarriage to the task and conditions.

  • Rubber belt undercarriages are very popular. They cause less harm to jobsite ground, are more stable and allow for quieter operation.
  • Steel tracks provide very high durability and are well suited for rough terrain, uneven surfaces, and hard rock.
  • Steel track with rubber pads provides both strength and long-lasting durability while avoiding damage to hard surfaces such as asphalt and concrete.
  • Retractable undercarriages are common across micro excavators, allowing you to navigate tight spaces and narrow entrances. Then they expand for increased stability while working.

Excavator Blade Options

  • Straight blades provide simple functionality, allowing the operator to backfill ditches, stabilize the machine while digging, and smooth rough ground.
  • Angle blades allow for enhanced grading and backfilling ability without the need for a second machine.
  • Blade float makes grading long distances easy. This option allows the operator to keep grade with minimal effort.

Excavator Options and Configurations

In addition to size, there are many options tailor designed for specific applications.

  • Variable angle booms are different than standard or fixed-arch booms. These excavators have increased versatility because they have greater reach and dig depth while being able to crowd material and dig all the way to the blade
  • Long reach excavators have longer sticks and booms. They are especially well suited to dredging and deep excavation.
  • Compact radius and zero tail swing excavators have counterweights that do not extend much or at all past the undercarriage. These machines are ideal in tight spaces, like between buildings. 
  • High flow models have increased hydraulic flow and pressure, necessary for the most powerful worktools.

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!
