When our operations team first came to me asking for a compact excavator, I thought I knew the answer. Buy it, obviously. That's how we do things—own our equipment, depreciate it, done. That was my first mistake.
I'm an office administrator at a mid-sized construction company. I manage our equipment procurement and rental vendor relationships—roughly $800k annually across a dozen suppliers. When I took over purchasing in 2020, I assumed 'same specifications' meant identical results across vendors. It didn't. Now, after a few expensive lessons, I've learned to actually think through the rent versus buy question. Here's what I wish I'd known.
Why This Comparison Matters
The compact excavator market is crowded. You've got the SANY 60 (a solid entry-level mini excavator) and the SANY SY135C (a more capable small excavator often used for rental fleets). But the question isn't really which model—it's whether you should rent or buy one in the first place.
I'm going to compare renting versus buying across three dimensions: total cost over time, operational flexibility, and maintenance responsibility. And if you're expecting me to wrap up saying 'buying is better,' you might be surprised.
Dimension 1: Total Cost Over Time
Let's start with the obvious—money. When I first calculated costs, I compared purchase price versus daily rental rate. That's a rookie mistake.
Buying: The SANY 60 excavator specs suggest a purchase price in the $35k–$45k range (depending on attachments and delivery). That's a big upfront hit. But over 5 years with moderate usage—say 500 hours per year—that averages to $14–$18 per hour, not including interest or depreciation. If I remember correctly, we ended up financing ours at about 6% in 2023.
Renting: Rental rates for a SANY SY135C small excavator for rent at a local dealer run about $250–$350 per day. For a week, that might be $800–$1,200. Per hour, that's more expensive at low usage—but if you only need it for a specific project, it's cheaper. I learned never to assume the daily rate is the real cost: after we rented one for a month in 2024, we were hit with a delivery fee, a pickup fee, and a small damage waiver. That added $400 we didn't budget for.
Conclusion: For high usage (over 200 hours per year), buying is almost always cheaper. For low usage (under 100 hours per year), renting comes out ahead. What surprised me? The break-even point isn't as sharp as you'd think—it depends heavily on how good your rental vendor is. A bad rental deal can make buying look like a bargain.
Dimension 2: Operational Flexibility
This is where the admin buyer in me gets interested. We didn't have a formal equipment approval process. Cost us when an unauthorized rush rental showed up on the invoice.
Buying: When you own a machine like the SANY 60, it's yours. You deploy it when you want, for any project. No calling a vendor at 7 AM to see if it's available. I've had mornings where I needed a plate compactor and a mini excavator on the same site—owning the SANY 60 meant it was sitting in the yard, ready to go. That kind of responsiveness is hard to value until you've missed a deadline because the rental yard was out of stock.
Renting: On the other hand, renting gives you fleet flexibility. Need a different size? Want an SY135C instead of the smaller 60? No problem—you just switch. Buying locks you into one machine. We bought a 60, and then our next project needed a larger machine. Suddenly we had an idle asset and a rental cost. If I'd rented, I'd have just swapped out.
Conclusion: Buying wins on availability, renting wins on adaptability. I'd say this: if your projects are predictable (same sizes, same locations), buy. If they vary wildly every quarter, rent. That said, we chose wrong our first time—I assumed our projects were predictable, and they weren't.
Dimension 3: Maintenance Responsibility
Here's the one that caught me off guard. The third time we ordered the wrong consumables for our owned excavator, I finally created a verification checklist. Should have done it after the first time.
Buying: You own the maintenance. Greasing the pins, tracking oil changes, sourcing replacement filters—that's all on you. The cost isn't just parts; it's time. Our team lost half a day when a hydraulic line blew, and nobody knew the correct part number. We had to call three dealers. That downtime cost easily $1,000 in lost productivity.
Renting: With rental, maintenance is the vendor's problem. If a machine breaks, they bring a replacement. I'm not a logistics expert, so I can't speak to carrier optimization—but I can tell you from a procurement perspective that a vendor who doesn't handle breakdowns quickly is a bad partner. (Should mention: we switched to a rental vendor in 2023 after our previous one took 48 hours to deliver a replacement. That 48 hours meant we missed a concrete pour deadline.)
Conclusion: Renting eliminates maintenance headaches. But you lose control over how the machine is maintained. We rented a machine once that came with a poorly maintained plate compactor attachment—bent base plate. That cost us a day of work. You trade one set of problems for another.
A Perspective That Changed My Mind
I'll admit: I started this process thinking buying was always the better long-term move. It wasn't until I got into the details—attachments, delivery fees, idle time—that I realized the decision isn't about the machine. It's about the workflow.
If you're buying a SANY 60 for a steady rental fleet or a predictable job site, do it. The specs are solid: the 60 has a reliable Yanmar engine, decent reach, and good breakout force. But if you're a general contractor who needs a machine for a few weeks, or if your project sizes change constantly, renting a SY135C small excavator for rent is likely a better call.
Oh, and I should add—don't forget to factor in how you'll even get the machine to the site. Do you own a trailer? Can your truck tow it? We ate $1,200 in transport costs our first year because I assumed our team had the right towing capacity. (Turns out, not a great assumption.)
Final Recommendation
This gets into operational territory, which isn't my expertise. I'd recommend consulting your project managers or even a rental specialist before finalizing. But from a procurement perspective, here's my rule of thumb:
- Buy a SANY 60 excavator if: You have consistent, ongoing work within its size class. You have a maintenance system in place. You're okay with the upfront cost and depreciation.
- Rent a SANY SY135C if: Your workload is project-based. You need flexibility in machine size. You don't want to manage maintenance or storage.
One last thing: pricing as of January 2025. Verify current rates with your local dealer—they change often. And whatever you do, don't assume the first rental quote is the best one. We saved 15% by asking three vendors to bid on the same scope. That was a lesson I only had to learn once.
