Mini Excavator Comparison: Choosing the right mini excavator can be a frustrating and time-consuming task with so many different makes and models. Buying the wrong model can lead to inefficient performance, expensive operating costs, and delays on the job site. If you don’t know the well-known and unpublicized key features and capabilities, you could very easily buy the wrong machine for yourself.
Think about starting a project with a mini excavator that doesn’t have enough digging depth or power for tough soil conditions. Or maybe the machine is too big for a lot of your confined areas and became really difficult to maneuver and operate. Those mistakes eat into your profits and slow down production.
Here are just a couple of examples. Looking for a mini excavator that’s great in super tight spots? The Caterpillar 301.7 CR is almost unbeatable there. But you want to do landscaping or foundation work? The Kubota U35-4 probably is your better machine because of its enhanced stability. By looking at operating weight, engine power, dig depth, and other features, finding the right excavator for your job becomes relatively simple.
1. Key Factors to Consider For Mini Excavator Comparison
Several factors will ultimately determine the best mini excavator for the job. Once you understand these factors, you can pick the most productive mini excavator for your construction, landscaping, or utility projects.
1.1. Operating Weight
One of the critical factors to consider when choosing a mini excavator is the machine’s operating weight because this determines digging stability and digging ability. Heavier machines are more stable under load and dig deeper, which is useful for tough digging conditions. If you want to dig deep with smooth machine operation, purchase a heavier mini-excavator. For a small machine with digging depth in soft soil to hardpan, you need a heavier machine. The flip side is that a lighter machine is good if you need something to get into a super confined space, or you need something to stay balanced for soft soils.
| Poids opérationnel | Ideal Applications |
|---|
| Below 2,000 kg (4,400 lbs) | Indoor demolition, tight spaces, and small landscaping projects |
| 2,000 – 4,000 kg (4,400 – 8,800 lbs) | General construction, trenching, and light earthmoving |
| Above 4,000 kg (8,800 lbs) | Heavy digging, grading, and demanding job sites |
1.2. Engine Power
Engine power will directly affect the mini excavator’s performance. The higher the horsepower, the more digging power you will have and the faster your cycle times. On the other hand, lower horsepower often equates to better fuel economy and a quieter machine.
| Engine Power (kW/HP) | Mieux pour |
|---|
| Below 20 kW (27 HP) | Small-scale tasks, indoor jobs, and landscaping |
| 20 – 30 kW (27 – 40 HP) | General construction and trenching |
| Above 30 kW (40 HP) | Heavy-duty excavation and demanding earthwork |
1.3. Digging Depth
An example would be digging depth. If you’re trenching out for a utility line, you need a mini excavator that can dig deep. If you’re digging foundation footings for a new house, you need a bigger machine or one that can dig deeper. If you’re trenching for a storm drain, you guessed it, you need a machine that can dig deeper. A machine that can’t dig deep is not the right machine for the job.
| Profondeur de creusement maximale | Recommended Usage |
|---|
| 2 – 3 m (6.5 – 10 ft) | Utility trenching, small foundation work |
| 3 – 4 m (10 – 13 ft) | General construction, road maintenance |
| 4 m+ (13 ft+) | Deep foundation digging, major earthworks |
1.4. Hydraulic System
The final item on your list is the hydraulic system. As the heart of any mini excavator, the hydraulic system should power the machine like a ninja, aggravating the neighbor’s dog, and with pinpoint precision. A good hydraulic system also has a lot to do with a machine’s power, especially when operating several attachments, like an auger, hammer, or grapple. If your machine operates like a turtle swimming in mud, you picked the wrong model.
1.5. Size and Dimensions
When you are on a job site with tight confines or have limited access, the size of the compact excavator is crucial. Mini machines with smaller dimensions can go through doorways, travel down small alleys, fit between houses in subdivisions, and work in tight quarters with ease. It’s easier to work with a small machine that works great.
1.6. Fuel Efficiency
When choosing a smaller model to rent or purchase, understand the machine’s limits, and don’t force it past them, regardless of the consequences. If you get a machine that is too small just to save a few bucks on day-to-day rent, it will cost you more in operating expenses. Quite frankly, you’ll be unhappy with the rental equipment, which never turns out well. So, rent the right machine for the job.
