The History Behind Leeboy’s Grading Machines
Leeboy, founded in 1964 in North Carolina, began as a manufacturer of asphalt pavers and quickly expanded into compact road maintenance equipment. By the early 2000s, Leeboy graders had carved out a niche in municipal fleets, small contractors, and rural road departments. Unlike full-size graders from Caterpillar or John Deere, Leeboy’s models were designed for tight spaces, lower operating costs, and simplified controls.
The Leeboy 685 and 785 series graders became particularly popular in North America, with thousands of units sold across county road departments and private contractors. Their compact size, hydrostatic drive, and mechanical simplicity made them ideal for gravel road shaping, shoulder maintenance, and light snow removal.
Design Philosophy and Operator Appeal
Leeboy graders are built around accessibility and ease of use. Most models feature:
An operator in Saskatchewan once described his Leeboy 685 as “the pickup truck of graders”—easy to maneuver, quick to learn, and reliable in rough terrain. That sentiment is echoed across rural America, where these machines often serve as the backbone of gravel road upkeep.
Hydraulic and Mechanical Considerations
Despite their simplicity, Leeboy graders require attention to detail in maintenance. Common issues include:
Terminology Notes
Leeboy graders offer a range of cab configurations. Open cabs are favored in warmer climates and for visibility during shoulder work, while enclosed cabs with HVAC systems are preferred in northern regions. Controls are typically mechanical levers or simple joysticks, with minimal reliance on digital interfaces.
Seat suspension, visibility, and noise insulation are modest compared to premium graders, but adequate for short shifts and light-duty work. Some operators retrofit their machines with aftermarket seats or LED lighting to improve comfort and safety.
A contractor in Maine added a heated seat and auxiliary lighting to his Leeboy 785 to improve winter performance. The upgrades cost under $1,000 and made early morning snow grading far more tolerable.
Blade Control and Grading Precision
Leeboy graders excel in light grading tasks but require finesse for precision work. Blade adjustments are typically manual or hydraulic, with limited automation. For fine grading:
Parts Availability and Dealer Support
Leeboy maintains a strong dealer network across North America, with parts readily available for most models. Common replacement items include:
Recommendations for Long-Term Ownership
To maximize the lifespan and performance of a Leeboy grader:
Operator Anecdotes and Field Wisdom
A retired operator in Georgia recalled using a Leeboy 685 to grade church parking lots and rural driveways. He praised its maneuverability and low fuel consumption, noting that he could run a full day on less than 10 gallons.
In Alberta, a road crew used a Leeboy 785 to shape gravel shoulders after spring thaw. Despite muddy conditions, the grader’s articulation and mid-mounted blade allowed precise feathering without rutting.
Conclusion
Leeboy graders offer a practical, cost-effective solution for light to medium grading tasks. Their mechanical simplicity, compact footprint, and operator-friendly design make them ideal for municipalities, contractors, and rural road crews. While not built for heavy-duty mining or highway construction, they excel in the everyday work of shaping roads, shoulders, and lots. With proper maintenance and thoughtful operation, a Leeboy grader can deliver decades of reliable service and smooth results.

Design Philosophy and Operator Appeal
Leeboy graders are built around accessibility and ease of use. Most models feature:
- Hydrostatic transmission for smooth speed control
- Articulated frames for tight turning radius
- Mechanical or joystick blade controls
- Open or enclosed cabs depending on configuration
- Perkins or Cummins diesel engines ranging from 80 to 130 horsepower

Hydraulic and Mechanical Considerations
Despite their simplicity, Leeboy graders require attention to detail in maintenance. Common issues include:
- Hydraulic Drift: Blade cylinders may slowly retract due to internal seal wear. Repacking the cylinders restores holding pressure.
- Steering Play: Articulated joints can develop slack over time. Replacing bushings and checking torque specs helps maintain precision.
- Pump Noise: Hydrostatic pumps may whine or chatter if fluid is contaminated or filters are clogged. Regular fluid analysis is recommended.
- Electrical Gremlins: Older models with analog gauges may suffer from grounding issues or corroded connectors, especially in humid climates.
Terminology Notes
- Hydrostatic Drive: A transmission system using hydraulic fluid to vary speed and torque without shifting gears.
- Articulated Frame: A jointed chassis allowing the front and rear halves of the machine to pivot independently.
- Blade Drift: Unintended movement of the grading blade due to hydraulic leakage or pressure loss.
- Valve Block: A centralized unit housing multiple hydraulic control valves.

Blade Control and Grading Precision
Leeboy graders excel in light grading tasks but require finesse for precision work. Blade adjustments are typically manual or hydraulic, with limited automation. For fine grading:
- Use short passes and frequent blade angle adjustments
- Maintain consistent travel speed to avoid washboarding
- Check blade wear and replace cutting edges regularly
- Use articulation to feather edges and shape crown profiles
Parts Availability and Dealer Support
Leeboy maintains a strong dealer network across North America, with parts readily available for most models. Common replacement items include:
- Hydraulic filters
- Blade cutting edges
- Steering bushings
- Electrical connectors
- Seat assemblies
Recommendations for Long-Term Ownership
To maximize the lifespan and performance of a Leeboy grader:
- Perform hydraulic fluid analysis every 500 hours
- Grease articulation joints weekly
- Inspect blade cylinders for drift monthly
- Replace cutting edges every 1,000 hours or sooner in abrasive conditions
- Keep electrical connectors clean and dry
