This was accurate as of mid-2024. The heavy equipment market shifts fast—especially with emissions rules and supply chain quirks—so I'd suggest verifying current pricing and lead times with a local dealer before making a final decision.
Comparing the Leeboy 685 Grader vs. Full-Size Motor Graders
If you're a contractor debating between a Leeboy 685 grader for sale and a full-size motor grader from one of the big names, you're not alone. I've been in that seat. In my role coordinating equipment procurement for a mid-sized paving company, I've handled roughly 30 grader acquisitions over the last four years—everything from small rental returns to capital purchases over $300,000.
Here's the honest take: the comparison isn't about which is 'better.' It's about which fits your actual jobsite, crew, and budget. And in a few key ways, the Leeboy 685 wins in places you might not expect.
We're going to look at this across three dimensions: jobsite mobility & access, operating cost & maintenance, and versatility disguised as specialization. Let's dive in.
Jobsites & Mobility: The Size Factor Isn't Overrated
This was the biggest surprise for me. I used to think 'bigger blade = more work per pass.' But on a tight commercial site or a neighborhood resurfacing job, a full-size grader (think 140-class or larger) becomes a liability, not an asset.
Leeboy 685 Grader
- Overall width under 8 feet. This means it fits through standard gates, between curbs, and on narrow shoulders without blocking traffic.
- Turning radius is tight enough to work cul-de-sacs and roundabouts in a single pass setup.
- Ground pressure is lower—less risk of tearing up soft base material or finished subgrade.
Full-Size Motor Grader (140–160 HP class)
- Width is around 8.5 to 9 feet. That 6–12 inch difference sounds minor until you're scraping against a jersey barrier or trying to squeeze through a residential street with parked cars.
- Turn radius requires multiple three-point maneuvers in confined spaces.
- Weight can cause rutting on soft ground, especially in spring thaw or after rain.
The conclusion: For 80% of the small-to-medium jobs most paving and grading contractors handle—parking lots, driveways, subdivision roads—the Leeboy 685 grader is a better fit by a significant margin. The big grader only wins if you're running mile-long highway projects or heavy earthworks daily.
—or rather, I should qualify that. My experience is based on about two dozen jobs in the Midwest U.S., mostly asphalt and aggregate base. If you're in rocky terrain or doing mining work, the full-size machine still rules.
Operating Costs & Maintenance: Where the Leeboy 685 Really Shines
Here's where I got skeptical at first. A smaller machine that costs less upfront—surely the maintenance and part availability would be worse, right? Actually, no.
Leeboy 685
- Engine is a common diesel (often a Tier 4 Final Cummins or similar). Parts are widely available through Leeboy's parts network or aftermarket suppliers.
- Fuel consumption: roughly 2.5–3 gallons per hour under normal load. That's about half what a full-size grader burns.
- Hydraulics and drivetrain are simpler. Fewer joints, fewer leak points, less expensive hydraulic oil changes.
- Leeboy parts online ordering is straightforward—I've had same-day shipping on wear parts like blades and moldboard components.
Full-Size Motor Grader
- Fuel burn: 5–7 GPH is normal. On a 10-hour day, that's 20–30 gallons extra fuel cost—roughly an extra $80–$100 per day at 2024 diesel prices.
- Larger tires cost more to replace. A set of six 14.00-24 tires can run $4,000–$6,000.
- Transmission and axle service intervals are longer but costlier per service. Some require specialized dealer tools.
The conclusion: If you're running 800–1,000 hours per year on a grader, the Leeboy 685 will save you roughly $15,000–$20,000 annually in fuel and routine maintenance alone. That's not a small number for a mid-sized contractor.
"I learned these cost comparisons in 2022 when we ran a side-by-side trial on a six-month project. The numbers have held steady since, though fuel prices have fluctuated."
That said—if your shop already has a big grader and a mechanic trained on it, the savings from switching are less dramatic. The real benefit comes from replacing an oversize machine with one that fits the work.
The 'Specialization Trap'—Why the Leeboy 685 Is More Versatile Than You Think
This is the part that surprised my team. Everyone assumes a specialized grader like the 685 is less capable than a 'do-everything' full-size machine. But specialization doesn't always mean limitation.
Leeboy 685 Grader
- Can be fitted with a rear scarifier attachment—I've used ours to break up compacted base material on parking lot repairs.
- Blade side-shift and tilt are fully hydraulic, giving you precision control on slopes and crowns.
- Light enough to be towed on a trailer behind a dump truck. That's a game-changer for mobile crews—no need for a costly lowboy and CDL driver.
- A third of my customers use theirs solely for finish grading after a dozer or excavator does the bulk work. They don't need the brute force of a 30,000-lb machine.
Full-Size Motor Grader
- Of course they can do more heavy ripping and deep blading.
- But that capability comes with drawbacks—larger transport requirements, higher fuel costs, and more expensive wear parts.
- And realistically? On a residential street or parking lot, you're never using that extra 100 horsepower.
The conclusion: The Leeboy 685 grader isn't a 'lesser' version of a full-size machine—it's a purpose-built tool for a specific range of work. If that range is 80% of your jobs, it's arguably more versatile because it makes more of your jobs easier, cheaper, and faster.
So glad I convinced my boss to try the 685 before committing to a new full-size unit. Almost went with a big Cat 140 just out of habit. Dodged a bullet there—would've overspent by at least $40,000 on purchase price and ongoing costs.
When Should You Buy a Leeboy 685 Grader?
Based on my experience and our internal data from 30+ grader decisions, here's my take:
Buy the Leeboy 685 if:
- Most of your work is on sites under 5 acres
- You need to tow the grader frequently between jobs
- Fuel and maintenance costs are a major factor in your bid pricing
- You want a grader a less experienced operator can handle safely
- You value parts availability via Leeboy parts online ordering
Stick with a full-size grader if:
- You're doing highway reconstruction, heavy roadbuilding, or mining
- Your crew is experienced with full-size machine controls
- You need maximum blade pull for deep ripping and hard material
- You already own a fleet of full-size graders and standardizing is easier
That's the honest breakdown. No machine is perfect for every job—but the Leeboy 685 grader fills a specific niche that the big guys don't serve well. And sometimes, being the right tool for the right job beats being the biggest tool on the lot.
