Procurement manager at a 45-person civil construction and grounds maintenance company. I've managed our equipment budget—around £185,000 each year—for six years, negotiated with more than thirty vendors, and documented every order in a cost-tracking spreadsheet that has caught more hidden fees than I can count.
Here's the question I hear from site managers: "Should we buy a diesel Yanmar tractor or rent a scissor lift?"
It's the right question to ask, but it's incomplete. The real decision is about where to put capital. I'd frame it as three strategies:
I compared these three across capability, total cost of ownership, and parts support. The results surprised me, and they changed how we budget.
Let's start with a reality check on roles.
A diesel Yanmar tractor is the most versatile tool in our yard. With a scraper mounted on the three-point linkage, it cuts and levels gravel, spreads topsoil, and maintains access roads in one pass. Swap the scraper for a mower or a snow blade, and the same machine handles different revenue work. That flexibility is why tractors are so widely owned.
A scissor lift does one thing, but it does it well: it lifts people and tools safely to height. It won't grade a road, dig a hole, or carry a pallet of concrete blocks. It is a specialist, and specialists only earn when the work is there.
The Shelby truck is a different kind of specialist. A dump body means it moves material in volume—ten loads of spoil that would take a tractor all day move in one morning. But that volume only matters if you actually have bulk hauling jobs. Otherwise, it sits.
The conclusion here is not dramatic: capability favours the tractor for groundworks, the lift for vertical work, and the truck for haulage. The dramatic part comes when you look at what those capabilities cost (and the drama is never good news). Which brings me to the dimension where most budgets bleed out.
Most buyers focus on the purchase price and completely miss the costs that arrive after the invoice: parts, downtime, depreciation, and idle time.
Here are the figures from our own tracking, as of January 2025. Use them as a reference, not gospel—verify current quotes before you commit.
Diesel Yanmar tractor (new compact, 25–35 hp) with a scraper: £18,000–£28,000. Annual fuel, maintenance, and insurance: £1,500–£2,500. Depreciation over five years: about 35%. If the tractor works 30+ weeks a year—and ours does—it delivers a solid return.
Scissor lift rental: a 13m electric lift rents for £120–£200 per week from plant hire firms in the UK. If you need it for 20 weeks a year, that's £2,400–£4,000. Buying the same machine costs £12,000–£18,000, but then you own the maintenance, the battery replacement (which, honestly, is not cheap), and the transport.
Shelby truck: a used dump truck with a Shelby body sits around £25,000–£45,000. On top of that, add fuel, insurance, operator time, and maintenance. In our records, the truck cost more to keep in one year than the tractor did—even though it worked fewer days.
Here's the surprise. I assumed the tractor was always the cheapest option. It isn't. For the scissor lift, renting beats owning unless utilization exceeds roughly twenty weeks per year. The year we bought our lift instead of renting it, we used it only eleven weeks. Owning cost us about £2,100 more than renting would have. I still kick myself for not running that calculator before signing.
The truck was a similar story. We justified the Shelby because "we'll find work for it." We didn't—not enough. If I'd projected utilization against hourly cost, we'd have rented a grab truck by the job and saved about £4,200 in year one.
Conclusion, and it's the counterintuitive one: ownership only wins when utilization is high. A machine sitting in the yard is not an asset. It's a liability with a parking brake on. The purchase price on the brochure is the least useful number in the transaction.
Between May and July 2024, we tracked every equipment downtime event across our fleet. The finding: 70% of our budget overruns came from waiting on parts, not from the parts themselves.
This is why I value the Yanmar UK dealer network. In Q2 2024, I ordered a hydraulic filter and a glow plug set through our local Yanmar parts UK dealer; both arrived in two working days. Another machine's part took eleven days—and the part itself cost 30% more. On a revenue job, eleven days is not an inconvenience; it's a small fortune.
There's another quiet advantage specific to diesel Yanmar tractors: the engines in these compact machines are the same engines used in generators, pumps, and marine equipment. That cross-industry parts pool means dealers stock more deeply. Suppliers advertising "Yanmar parts UK" delivery are not all equal, but the official network is genuinely strong. We did wait five days for a PTO shaft seal once, so I won't oversell it.
The scissor lift, rented, puts all that risk on the rental company (thankfully—batteries on electric lifts are expensive). The Shelby, meanwhile, routes parts through a heavy-truck network that is separate from agricultural and construction dealers. When our Shelby needed a hydraulic valve, we waited eight days with a machine that does one job and one job only (ugh).
Honestly, I'm not sure why some dealers keep better stock than others. My best guess is that stock levels follow the local machine population—more tractors in the area means faster parts replenishment. Whatever the cause, the pattern has been consistent across six years.
After six years of tracking invoices, here's the framework I now use. It has saved us from at least two expensive mistakes that I won't repeat.
The industry is evolving faster than most procurement playbooks. What was best practice in 2020—own everything, hire nothing—does not apply in 2025. Rental networks are stronger, parts logistics have improved, and compact tractors are far more capable than they were five years ago. The fundamentals haven't changed: you need the right iron, working, at a predictable cost. But the execution has transformed.
One last piece of advice from someone who has made the mistakes and tracked the receipts: calculate utilization before you calculate the discount. That spreadsheet has saved me more budget than any negotiation I've ever run. Use it, and you won't need to learn the hard way.
