What Size Excavator Do You Really Need? A Contractor’s Guide to Choosing the Right Fit

8/7/2025

Choosing the right excavator isn’t just about picking the biggest machine available — it’s about matching the equipment to the work. Whether you're trenching, digging footings, doing site prep, or working on a residential or commercial project, selecting the right size excavator can save you time, money, and effort.

Here’s a simple breakdown to help you decide what size excavator fits your needs — and why machines from Kubota’s proven lineup are a smart, dependable choice.

Mini Excavators (0 – 6 tons)

Best for:

Residential construction
Landscaping
Trenching for utilities
Working around structures or tight job sites
Fence installation, small foundations, and irrigation

Mini excavators like the Kubota U17 or U27 are compact and easy to maneuver, but don’t let their size fool you — these machines pack serious performance. They're ideal when you're working in confined spaces or trying to minimize impact on finished landscapes or concrete.

They’re also more affordable to transport and rent, making them a great solution for contractors who need efficiency without bulk, or landowners taking on one-time jobs.

If your project doesn’t require deep digging or heavy lifting, a mini excavator is often the smartest (and most cost-effective) option.

Mid-Size Excavators (6 – 10 tons)

Best for:

Utility and site prep work
Agricultural or ranch projects
Commercial construction
Digging trenches, setting tanks, lifting materials
Jobs requiring more digging depth or reach

Mid-size excavators like the Kubota KX040-4 or KX080-5 strike a solid balance between power and maneuverability. They're designed to handle more demanding work than minis, but they’re still easy to transport and use on a wide variety of jobs.

For many contractors, a mid-size machine is a versatile workhorse — capable of handling attachments like breakers, thumbs, and augers — without stepping into the high costs and logistics of larger machines.

Large Excavators (10+ tons)

Best for:

Major commercial or industrial construction
Road building
Mass excavation
Projects requiring deep or heavy-duty digging

There’s no doubt that large excavators have their place on the biggest jobs — but they’re not always the right fit. For many everyday projects, a large excavator might be more machine than you need. These units often come with higher upfront costs, specialized transport requirements, and tighter operating space restrictions.

If your work calls for heavy lifting, deep trenching, or long reach — and your jobsite allows for it — a large excavator can be worth it. But for a majority of local contractors and landowners, mini and mid-size models can deliver the same results with less hassle.

Why Choose a Kubota Excavator?

Whether you’re working with compact or mid-size machines, Kubota excavators are known for their durability, comfort, and performance. Here’s what sets them apart:

Reliable Kubota diesel engines for long-lasting power
Tight tail swing designs for working close to walls or buildings
Easy-to-use controls for operators of all experience levels
Smooth hydraulics and excellent digging force
Comfortable, quiet cabs to reduce fatigue on long jobs
Attachment-ready for even more versatility

Kubota’s range of excavators is built for real-world jobs — whether you’re digging trenches on a ranch, prepping a pad site, or tackling tight city work.

Not Sure What Size You Need? Start Here.

Choosing the right excavator comes down to a few key questions:

What kind of job are you doing?
For tight spaces or light digging, a mini excavator is often perfect. For deeper trenches, heavier lifting, or bigger site prep, consider a mid-size model.
How much space do you have?
Working around buildings, fences, or in residential areas? Go compact. Open land or larger jobsites give you more room to use a bigger machine efficiently.
How deep or far do you need to dig?
Mini excavators dig around 7–9 feet deep, mid-size machines like the KX040-4 or KX080-5 offer over 11 to 15 feet of reach — perfect for most construction or ag jobs.
What are you moving?
Lighter material like dirt or mulch? A mini is more than capable. Heavier loads like pipe, rock, or dense soil may call for a mid-size machine with more lift capacity.
How often will you use it?
For short-term projects, renting is cost-effective. For frequent use, buying may be the smarter investment — especially with financing options and tax advantages.
