Liugong 925E vs 9035E Mini Excavator: A Contractor's Total-Cost Comparison

I'm not going to tell you that the Liugong 9035E mini excavator is a better machine than the Liugong 925E excavator. On an open site, the 925E will out-dig it, and there is no point pretending otherwise. But my company doesn't work on many open sites. We dig pools, patch drainage, repair water lines, and squeeze between fences and existing patios. In that world, machine size is only one line of the cost sheet.

Quick background: I have managed equipment for a small excavation contractor for about 11 years, and I've personally made four significant equipment-selection mistakes. The total wasted budget was roughly $26,000. I wrote our current pre-buy checklist after mistake number three in Q1 2024, and this comparison comes from that checklist, not from a brochure.

Why Are a 22-Ton Excavator and a 3.5-Ton Mini in the Same Article?

On paper, a Liugong 925E excavator (22-ton class) and a Liugong 9035E mini excavator (3.5-ton class) aren't competitors. They're different weight classes with different hydraulics, different undercarriages, and different price levels. Putting them side by side looks misleading.

But small contractors are often choosing between two business setups rather than two machines:

• Setup A: own one big excavator like the 925E and move your work toward large, open sites.
• Setup B: own a compact 9035E, handle the many tight jobs available, and rent a 22-ton machine only for the few days a year when mass excavation shows up.

These setups have very different total cost profiles. That's why this comparison isn't about horsepower. It's about the costs that aren't in the base quote.

Access: Where a Full-Size Excavator Loses Money

The first expensive lesson came in September 2017. I booked a full-size excavator for a backyard pool because the hourly rate looked great on paper. The machine arrived at a 5-foot gate and did not fit. We removed fence panels, drove across a paver walkway and a septic inspection cover, and then spent the next week dealing with the consequences.

The same project would have been slow but clean with a 9035E mini excavator. A compact machine fits through openings, has a shorter tail swing, and leaves more room to place spoil and material around the hole. More importantly, it doesn't force you to widen access by damaging what's already built.

Conclusion on access: when a large share of your revenue comes from occupied lots and residential backyards, the big machine's digging speed never matters because it doesn't reach the work.

Water Pumps and Pool Jobs: The Hidden Pump Side of a Dig

The surprise wasn't the price difference between machine classes. It was how often the schedule was controlled by water. Excavating a pool, a basement, a utility trench, or a drainage line in wet ground means dealing with groundwater, and an excavator does not make water disappear.

This is where a dewatering water pump becomes the most important piece of support equipment on site. A 2-inch or 3-inch trash water pump, the right suction hose, and a discharge line can keep a hole dry enough to continue work, and the machine you chose matters less than having that pump ready before you dig. I learned that after losing most of a day waiting on a rental pump that should have been in the truck at the start.

Pool jobs are also pump-heavy jobs in a second way. Once the shell is in, the equipment pad gets graded and set, and a pool pump and filter start doing the circulation work. The contractor who ignores the water side—both the temporary water pump during excavation and the permanent pump pad around the pool—ends up paying for downtime.

Transport: How to Load a Mini Excavator on a Trailer Safely

Transport cost is where the comparison gets concrete. A 925E or any 22-ton excavator usually needs a lowboy or float trailer, a heavier tow vehicle, and often someone with the proper license and insurance to move it. That cost appears on every single mobilization.

Moving a 9035E is completely different. I tow it behind a heavy-duty pickup on a properly rated equipment trailer. In practical terms, that's how to load a mini excavator on your own trailer without turning the move into a major production. Here's what has worked for us:

1. Check ratings before anything else. The trailer's payload rating must exceed the machine's working weight, including bucket, cab, and undercarriage, by a comfortable margin. Verify against the spec plate on the machine and the trailer.
2. Set up on firm, level ground. Chock the trailer wheels, and lower stabilizers if the trailer has them. A spotter stands well away from the machine and the ramps, never between the track and the trailer.
3. Load straight and slow. Keep the upperstructure facing forward, the bucket low, and approach the center of the ramps at a steady track speed. No swinging while moving.
4. Once on the deck, position the machine centered front to back, lower the bucket and blade so the machine cannot rock side to side, and chock both tracks.
5. Use four separate tie-downs. Attach them to the manufacturer's designated securement points, not around hoses or cylinders, and tighten from opposite corners.
6. Recheck everything after the first few miles. Trailer straps shift, and the first ten minutes shows it.

That whole process is a 20-minute part of the day. By comparison, a full-size excavator move involves booking a truck, coordinating road permits in some areas, and paying for a machine that does mostly nothing while it sits in transit. When you run the numbers, this one dimension can change the purchase decision by itself.

Total Cost of Ownership: What I Misjudged for Years

My recurring mistake was comparing unit prices, rental rates, or operating rates while ignoring the full system around the machine. The TCO for a setup includes purchase or rental cost, financing, insurance, transport, maintenance, support equipment, and the cost of jobs you cannot do because the wrong machine is on site.

Bigger machines have bigger versions of every one of those line items: more fuel, larger filters, higher tire or track costs, heavier tow requirements, and higher repair bills. A big excavator makes sense when it runs. It's painful when it sits. After the third mistake, I built a one-page checklist that starts with utilization, access, transport, and water management, and only then asks which machine price wins.

To be fair, I get the appeal of one big versatile machine. A 925E can do site prep faster, break pavement that a mini can't, and reach deep basements with less effort. For a contractor with steady large-site work, that is a productive machine, not a mistake.

For my job mix, the math flipped. The compact machine earned on small jobs consistently, moved itself for nearly no cost, caused less site damage, and let us rent a big excavator for the rare days when we truly needed one. Over the past 18 months, we rented a full-size machine on nine days total while our 9035E worked through the season. That is utilization the big iron would never have achieved in our market.

Which Setup Fits Your Contractor Profile?

Scenario one: most of your work is in open spaces. You're cutting pads, digging ponds or basements, and mobilizations are few. A Liugong 925E excavator can earn its position in your fleet. Match it with a maintenance program and a consistent schedule, and the bigger machine wins.

Scenario two: most of your work is residential, tight, or access-limited. You're doing pool digouts, water lines, drainage repairs, and landscaping jobs where the opening is a gate and the neighbor's driveway is the machine yard. A Liugong 9035E mini excavator, a decent equipment trailer, and a reliable water pump will likely produce more net profit because they show up every day.

There is a third scenario: you're not sure of your job mix yet. In that case, starting smaller and renting bigger when needed is the lower-risk path. You can always size up after a year of field records. Sizing down after buying a 22-ton machine is a much more expensive lesson.

As of February 2025, exact weights, transport dimensions, and configurations vary by dealer spec, cab options, and undercarriage choices. Verify the current Liugong specs and your trailer ratings before signing anything. The point isn't that one Liugong model is universally better. The point is that total cost of ownership, not the base price, should make the call.
