Leeboy Graders and Parts: An Honest FAQ From Someone Who Signs the Checks

I manage equipment and parts procurement for a 40-person road construction company. About $600K a year in fleet and parts spending. Eight years running. I've negotiated with enough vendors that I've stopped trusting first quotes—and I've made enough mistakes to know which corners you can't cut.

People ask me about Leeboy equipment for a few recurring reasons: they're comparing graders, they need parts, or they're trying to figure out if a small grader can handle full-size work. And then there are the questions that make me wonder how they got my number. Here's what I tell them.

What's the real case for a Leeboy motor grader—and when is it overkill?

Leeboy motor graders are built for site grading: road shoulders, parking lots, utility corridors, drainage work. The 635 and 685 models are what I see most in mid-size road contractors' fleets. Bigger operations go for the 785 or 8500.

Here's where I'll be honest: if you're grading at highway scale, a Leeboy isn't going to replace a full-size production grader. It's not designed for that. In my experience, these machines cover about 70% of contractor scenarios. If your jobs are parking lots, access roads, and residential subdivisions, you're probably in that 70%. If you're doing interstate work at scale, you probably aren't. Know which category you're in before you sign.

Leeboy parts—OEM, aftermarket, or rebuilt?

I've bought all three, and I'll save you the trouble: OEM for anything hydraulic or electronic. Aftermarket for wear items.

Aftermarket parts run about 40% cheaper on average, based on our 2023 parts audit. But the failure rate in my experience is roughly double. They warned me about non-OEM hydraulic components. I didn't listen. A pump failure cost us $2,400 in parts and downtime—more than three years of the OEM premium on that part. That settled it.

To be fair, aftermarket parts have gotten better. Some are fine. But downtime kills a road crew's schedule, and I've learned to price that into the decision, not out of it. Rebuilt parts? I've used them for non-critical components. Wouldn't touch them for a hydraulic pump.

When does a small Leeboy grader make sense over a bigger machine?

When you need grading but can't justify $150K+ on a full-size machine, or when the site's too tight to get one in. We run a small Leeboy on about 30% of our site prep jobs—the 635 and 685 range. It's not fast. But it gets into places a full-size grader won't fit and does the work without a rental.

Not ideal, but workable.

The tradeoff is pure productivity. A small grader might take twice as long on a job a full-size machine eats in half a day. But if the alternative is renting a full-size grader for a week at $800–1,200/day, the math flips fast. Run your own numbers—the answer depends on how many days per month the machine would actually work.

How do I avoid buying a used Leeboy that turns into a money pit?

Get a mechanic you trust to inspect it. Not the seller's mechanic. Ever.

I learned this the hard way in 2022 when we bought a used 685 based on a "great" report from the seller's shop. Three months and $3,600 in repairs later, we admitted the machine was a money pit. We now require a third-party inspection for every used purchase over $20K. Costs $300–500 per inspection. Worth every dollar—especially compared to a $3,600 repair bill on a machine we could've walked away from.

This approach worked for us, but we're a mid-size operation buying mid-range machines. If you're buying high-hour equipment for parts or resale, your calculus is different. I can't speak to that—only to what I've lived.

AC compressors on heavy equipment—why do they fail so often, and what do they cost?

AC compressors on heavy equipment are fragile, and plenty of buyers don't factor them into total cost of ownership. A replacement on a Leeboy motor grader runs roughly $1,200–$2,500 in parts depending on the model, plus labor. Based on quotes we've collected through Q1 2025.

In my experience, you get about 4–6 years before replacement is on the table—faster if you're running in dusty conditions (you are). A lot of contractors budget for engine maintenance and ignore the HVAC. The compressor doesn't care about your maintenance plan. It fails on its own schedule, usually the week you need the machine most.

Does the Leeboy dealer network actually matter for parts?

More than I expected. We're about 45 minutes from our nearest full-line Leeboy dealer, and that's not an accident. When a hydraulic hose blows on a Tuesday morning, the difference between a 45-minute drive and a 3-day wait for shipping is the difference between finishing the job and losing the contract.

Not every owner needs that proximity. If you're running a machine that's down for scheduled maintenance once a month, big-box shipping works fine. But if you're in heavy use—daily, on multiple job sites—dealer proximity is a hidden cost worth pricing. "Dealers near me" isn't just a search phrase. It's a real budget line.

"Nail drill"—what is this doing on my equipment searches?

If you're here from that search, you're in the wrong place. Leeboy doesn't make nail drills, and you won't find one on a motor grader. This is probably an SEO glitch—keyword tools sometimes group unrelated terms, or a search engine got confused between construction tools and power tools.

If you actually need a nail drill, talk to a power tool manufacturer. Not a heavy equipment dealer. Honest answer: not our category.

What is a crane shot used for?

The full answer: a crane shot is a filmmaking technique—a camera movement where the rig rises or descends on a crane or jib arm. It's used in movies, TV, and commercial video to give scale and movement to a scene. Construction equipment doesn't use them. Filmmakers do.

That said, if you're hiring a video crew to film your Leeboy at work for a marketing piece, the videographer who knows what a crane shot is will charge you more. Crane rental alone runs $1,500–$3,000 per day, depending on the rig. But that's a marketing budget, not an equipment budget. Different conversation.

Bottom line: if you're shopping for a grader, this question doesn't apply. If you're shopping for a video crew, it does.

What's the one takeaway that actually matters?

It took me about 3 years and 150+ parts orders to understand that the cheapest option almost never ends up being the lowest cost. The used machine with the "great" inspection report. The aftermarket hydraulic pump. The full-size grader you rent once a month instead of buying. The math flips in ways you don't see until you're already in it.

Leeboy makes solid grading equipment. The dealer and parts network is one of the reasons I've stayed with them—availability matters more than people think until you're waiting on a backorder. But no machine is "best" in a vacuum. It's best for a specific job mix, a specific budget, and a specific crew. I can only speak to ours: 40 people, mid-size jobs, about 200 orders over 8 years and one very expensive used-machine mistake.

If your situation looks different—a smaller crew, bigger jobs, seasonal demand—your mileage may vary. The principles hold. The numbers won't.
