If you're looking at a Komatsu D85 bulldozer for your first major equipment purchase, I'd say hold on. Most people—and I was one of them—assume the biggest machine is the best investment. But after managing purchasing for a mid-sized construction firm for the last four years, I've learned that the machine with the highest upfront cost and the biggest footprint often has the worst total cost of ownership. You're likely better off starting with a Komatsu mini excavator and a wheel loader.
Why I'm Skeptical of the 'Bigger is Better' Approach
In 2022, our operations manager pushed hard for a Komatsu D85EX-15. He'd run one years ago and loved it. The machine is a beast—perfect for heavy dozing and ripping. But when I ran the numbers for our specific projects (mostly site prep and utility work for commercial buildings), it didn't make sense.
The D85's purchase price was around $450,000. Then you add transport—you need a lowboy trailer and a permit for anything over 90,000 lbs. Our typical job site was tight, with limited turning radius. The D85 is 12 feet wide. It wouldn't fit through standard gate openings. We'd have to dismantle fencing or work around the schedule of a larger crane. Plus, the fuel consumption is roughly 8-10 gallons per hour under load. That's $80-$100 an hour just in diesel.
Instead, we bought a Komatsu PC88MR-10 mini excavator (about $85,000) and a WA320-8 wheel loader (around $200,000). Total cost: $285,000. The mini excavator could get into those tight spots, and the loader handled material moving more efficiently than a dozer ever could on our flat sites. The D85 would have been a monument to our ambition, but a disaster for our cash flow.
The D85 Makes Sense For...
I'm not saying the D85 is a bad machine. It's legendary for a reason. But its sweet spot is specific:
- Large-scale mining or quarrying. Think moving thousands of yards of overburden daily.
- Heavy land clearing. If you're pushing trees and stumps all day, a dozer is the tool.
- Road building on raw terrain. Cutting and filling for highways.
If your work is primarily utility trenching, building pads, or landscaping, a D85 is overkill. You'll burn money on fuel and idle time. Take this with a grain of salt—I'm not a heavy civil engineer—but from a purchasing standpoint, the numbers didn't work for us.
The Total Cost of a Komatsu Excavator: More Than the Sticker Price
Here's a practical example from last year. We were comparing two quotes for a Komatsu PC200-8 excavator. Vendor A offered it for $180,000. Vendor B quoted $195,000. Easy choice, right? Wrong.
Vendor A's quote was 'machine only.' No delivery (that was $4,500 extra), no bucket (add $2,800), no hydraulic thumb ($3,200), and no warranty beyond the standard one year. Vendor B's quote included delivery, a set of buckets (general and trenching), a mechanical thumb, and a 3-year/5,000-hour powertrain warranty.
When I totaled the TCO over 3 years:
- Vendor A: $180,000 + $4,500 delivery + $6,000 for bucket and thumb + estimated $12,000 for two minor repairs (out of warranty) = $202,500
- Vendor B: $195,000 + $0 delivery + included attachments + warranty = $195,000
The 'cheaper' machine was $7,500 more expensive in the end. And that $12,000 repair estimate is conservative. A final drive motor failure on a PC200 can easily run $7,000-$10,000. Oh, and Vendor A's delivery window was '4-6 weeks, give or take.' Vendor B delivered in 3 weeks. Time is money when a project is waiting. So glad we didn't take the bait on the lower sticker.
Bidets, Pool Pumps, and Reach Trucks: The Randomness of Admin Purchasing
Here's where my job gets weird. One week I'm approving a $200,000 excavator. The next, I'm comparing bidet attachments and pool pumps. This is the reality of being an admin buyer in a company with diverse needs. We're a 400-employee firm with 3 locations, and I process about 60-80 purchase orders annually across 8 different vendor categories.
Bidet Attachments: A Lesson in Specs
Six months ago, our facilities manager asked for a bidet attachment for the main office. Sounded simple. It wasn't. The cheap $40 model had terrible reviews (leaks, weak spray). The $150 'premium' one required a specific toilet shape. I'm not 100% sure, but I think we ended up with a Toto washlet that was $400 after installation. The lesson: for anything with plumbing, the upfront cost is meaningless if you can't return it after installation. I now always include 'returnability' in my TCO for non-standard items.
Pool Pumps: The Vendor Who Bungled it
We needed a pool pump for the employee recreation area. I found a great price from a new vendor—$350 cheaper than our regular supplier. Ordered it. They couldn't provide a proper invoice (handwritten receipt only). Finance rejected the expense report. I ate $350 out of the department budget. Now I verify invoicing capability before placing any order. The reliable local vendor at $650 was actually cheaper than the $300 online gamble.
Reach Truck vs. Forklift: A Common Debate
This is a classic choice for our warehouse. A standard counterbalance forklift (like a Komatsu FG25) is great for loading trucks and moving pallets around a flat yard. But for narrow aisles and high racking, you need a reach truck.
The assumption is that a forklift is cheaper and more versatile. The reality is a reach truck can double your storage density, which saved us from renting offsite storage. We leased a Toyota reach truck for about $1,200 a month. It paid for itself in 8 months by freeing up floor space. So the cheaper machine (a forklift) would have been the more expensive decision.
What About Komatsu Under Warranty / Service?
People think expensive dealers deliver better service. I've found it's the other way around. Dealers who deliver quality service can charge more. We had a catastrophic final drive motor failure on a Komatsu PC130 just before a big project deadline. The local dealer first said 'two weeks for parts.' After I escalated twice, they found a reman unit in stock and had our tech install it in 3 days. Cost was $8,500. But the alternative—two weeks of downtime on a $1,500/day project—would have been a disaster. The dealer's ability to prioritize us (because we'd built a relationship) was worth the premium.
Honest Limitations: When This Advice Doesn't Apply
I should add that my TCO framework has limits. If you're a cash-strapped startup and the difference between a $450,000 D85 and a $285,000 combo is the difference between buying and not buying, you buy the dozer and make it work. Cash flow is king.
Also, this is my experience as an admin buyer for a company that does $10M+ in annual revenue. A smaller operation might be better off with used equipment or a different mix. And if you need a bidet attachment? Just buy the Toto. Trust me.
