If you've ever asked whether you should buy a compact excavator, a skid steer, or a scraper, you know the challenge: there's no straight answer until you dig into your own numbers. I've managed equipment and procurement budgets for a mid-sized contracting company for the last six years, and I still start every purchase with the same question: what's not included in the sticker price?
Trust me on this one. The machine that keeps working is usually the one that makes sense for your specific workload, not the one with the fastest demo.
Start by putting yourself in a scenario
I structure equipment decisions into four common scenarios. If you're honest about which one you're in, the choice gets clearer.
- You need digging and trenching capability, with a machine that can move between sites. The Doosan 75 excavator is worth comparing here.
- You need a compact loader for tight spaces, cleanup, loading, and material handling. A Kubota skid steer is probably on your short list.
- You need to move huge volumes of earth across an open job site. This is where a scraper becomes interesting.
- You already own a machine and it's running poorly. Before you buy more iron, find out if it's a fuel pump issue.
Notice what's missing: there's no 'best machine' category. That's deliberate. The most expensive equipment decision is buying the wrong class of machine at the right price.
When a Doosan 75 excavator makes sense
If your jobs are mostly digging, trenching, demolition cleanup, and utility work, the Doosan 75 excavator—or rather, the DX75 series—should be part of your comparison. It's a compact machine that still has enough reach and breakout force for a lot of common contractor work.
From a procurement view, the bigger reason I like the Doosan 75 is parts availability. We had a hydraulic hose fail in Q2 2024, and the dealer had the replacement in two days. A class-leading machine is useless if it sits for three weeks waiting on parts.
But here's what I see people miss: the buy price is not the total cost. I compared quotes for a used Doosan 75 excavator and a comparable model from another brand. The other brand's base quote was about $2,100 lower. Then I added delivery, freight insurance, a bucket wear package, and the first scheduled service. The other brand's final cost was $3,400 more total because those items were not included in the base price. The lower quote wasn't honest—it was just easier to compare at a glance.
Pull up the Doosan manual before you make your final call. If you can do oil changes, filter swaps, and minor electrical checks yourself, the ownership cost drops significantly. That's the kind of math I do in my cost tracking spreadsheet, not on the tailgate.
When a Kubota skid steer is the better answer
If your work is more about loading, carrying, grading, and cleaning up around a site, a Kubota skid steer may be the better fit. It won't dig like an excavator, but it can do many of the small jobs across a day. The SVL75 vertical lift model comes to mind, though I might be misremembering the exact specifications for the current generation.
The cost angle is real. A skid steer is often cheaper to own and run than a mini excavator when you're doing more material handling than digging. I saw a crew lose most of a day waiting for a loader that was too big for the gate, when a skid steer could have handled the entire pallet run in a couple of hours. That wasted day cost the project around $850 in crew time and downtime.
The same logic extends to forklifts. If you've got a Doosan forklift in the warehouse and it starts acting up, don't immediately book a dealer visit. I once had a lift that was throwing a warning code, and the dealer quoted $400 just for diagnostics. I ordered the Doosan forklift manuals from the local dealer, found a low hydraulic fluid level that wasn't setting off the gauge properly, and fixed it with $35 of fluid. The manuals paid for themselves on that one call.
When a scraper should enter your world
A scraper is a strange beast. It loads, carries, and spreads material without needing a separate excavator and dump truck cycle. If you're moving large volumes of earth on an open site, a scraper can give you the lowest cost per yard of material moved.
But scrapers are not for every contractor. They're expensive to maintain, and a bad tire or a ripped hydraulic hose can eat your margin fast. From the outside, owning a scraper looks like a way to cut earthmoving cost. The reality is that it only works when you have enough volume to keep it running and the haul distance is not absurdly long. If you're cutting a 40-space parking lot, rent one. If you're moving 100,000 yards for a subdivision, then talk to a salesman about ownership.
One more thing vendors won't tell you: the hourly rate quote is rarely the final number. There's usually a component charge for high-wear parts. I ask everyone to write down what's not included before I sign. That's not rude. That's procurement.
Before you buy anything: how to tell if fuel pump is bad
This is the least flashy but most valuable scenario. If your machine is hard to start, loses power under load, or dies unpredictably, do not assume you need a new engine or a new machine. Check the fuel delivery system first.
How to tell if fuel pump is bad? Most of the time, you'll see one of these patterns:
- Hard starting after the machine sits overnight, especially if the fuel tank is low.
- Engine sputters at high RPM or under load, then smooths out at idle.
- Loss of power when going up an incline or when the hydraulic system is working hard.
- Engine starts after hand priming, then dies once the bleed pressure drops.
- No fuel flow at the injector pump inlet when you crack the line while cranking. If you get nothing, work backward from the tank: pickup tube, fuel filter, then the pump.
I still kick myself for replacing a lift pump years ago without checking the fuel filter first. The pump cost $320. The actual problem was a clogged filter that cost $9. That mistake shows up in my notes every time I'm tempted to skip diagnostics.
A mechanical fuel pump can fail, but so can a cracked pickup tube, a plugged vent, a bad lift pump, or an air leak in the return line. If you're not certain, use the manual's troubleshooting chart. The Doosan 75 excavator and Kubota skid steer manuals both walk you through fuel flow checks before you pull a pump. If you own a forklift, the Doosan forklift manuals have the same structure. That's not a coincidence; it's a maintenance standard.
Bottom line: if the pump is bad, replace it. But verify first. A misdiagnosis costs you not just the part, but the downtime of a second repair.
How to decide which scenario you're in
If you're still torn, ask yourself three questions:
- What is the machine supposed to do every day? Digging points toward an excavator. Loading and cleaning points toward a skid steer. Large-volume earthmoving points toward a scraper. Material handling under a roof points toward a forklift.
- How many hours per month will it run? Higher hours justify better spare parts support and a dealer close to you. Low hours make rental a better answer.
- Can the problem be fixed instead of replaced? If the machine runs poorly, go through the fuel system before you decide it's worn out.
There's no universal answer, and anyone who sells you one is probably trying to close a deal. But there is a right answer for your site, your volume, and your budget. There's something satisfying about a machine that starts on the first crank and a budget that isn't surprised. Whether you're looking at Doosan, Kubota, or another line, keep the procurement mindset: get the full cost, use the manual, and check the fuel pump before you replace anything.
