Gravel driveways are one of the most common skid steer jobs in Canada — and one of the most frequently botched ones. The mistakes are predictable: wrong attachment, wrong pass direction, no crown, no drainage plan. This guide covers the full process from assessment through finishing, with real attachment decisions along the way.
Already know the attachment side and just need to compare box blade vs land plane? That's covered in detail in our box blade vs land plane comparison. This guide is about the grading process itself — the sequence, the technique, the drainage considerations.
Seriously. Walk it. Take 10 minutes to identify:
This 10-minute walk changes your entire plan. Skipping it and just driving up and down produces a flat, poorly draining surface that looks fine until the first rain.
Three attachments handle driveway grading on a skid steer. Each has a distinct role.
The bucket is what most people start with because it's what they have. It moves material well — scraping high spots and dumping into low spots — but it can't create a controlled crown and it's difficult to use for final finish passes. Use a bucket for the heavy work: filling ruts deeper than 6 inches, pulling material from edges back to centre, and redistributing large amounts of displaced gravel. Then switch to something else for finish grading.
One legitimate bucket trick: tilt the bucket back slightly (curl toward you) and drag it backward over the surface. This creates a mild grading action. It's imprecise but works for rough levelling when you don't have a blade on site.
A box blade is the most versatile option for driveway work. The cutting edge grades forward; the rear drag board smooths on the back pass. The box (the enclosed sides and rear) catches material and carries it, which lets you fill a low spot by collecting from a high spot in one pass.
Box blades are available in widths from 60" to 96". A 72" box blade is the standard for residential driveways — wide enough to cover the surface in a reasonable number of passes, narrow enough to maneuver in tight spots. Blade depth is controlled by angling the entire unit; most skid steer box blade mounts let you set the attack angle to control how aggressively the blade cuts.
The limitation of a box blade is that it requires skill to produce a consistent crown. You're manually holding the machine position and blade angle across the whole pass length. On a 200-foot driveway, small variances compound.
A land plane has a self-levelling mechanism — the blade section floats on a pivot and averages out undulations rather than following them exactly. This produces a smoother, more consistent final surface than a box blade, especially on longer driveways where operator variance would otherwise show up.
Land planes are better for maintenance grading (restoring a driveway that's still basically in shape). Box blades are better for restoration work (a badly rutted or washed-out driveway that needs real reshaping). If the driveway needs actual regrading, use a box blade for the heavy lifting and a land plane to finish. If it just needs spring maintenance, a land plane alone often does the job.
Order matters. Doing these out of sequence produces a driveway that looks done but fails in the first rain.
Drive along each edge of the driveway, pulling material from the edges toward centre. On a typical gravel driveway, the edges accumulate low-grade material (silt, organics, decomposed edge vegetation) mixed with the good gravel. Those edges need to come up and go toward the middle, not get pushed further out.
Keep the blade low enough to cut into the material, but watch the shoulder — you don't want to sink a wheel off the edge in soft spring conditions. If the edges are overgrown, a quick trim with a brush cutter attachment before grading saves a lot of frustration.
Work the centre of the driveway, pushing material from the ruts toward the edges (yes, this temporarily contradicts pass 1 — you'll bring it back). The goal here is to break up the compacted rut surface and loosen the gravel so it moves in subsequent passes. Deep ruts, 4"+ down, need bucket work first — a box blade can't fill a deep rut efficiently, it just bridges it.
Now make full-width passes from one end to the other, collecting from high spots and depositing in low spots. With a box blade, you're working the box — capturing material from high areas and releasing it gradually by adjusting the rear drag. This is the pass that actually shapes the surface.
This is the critical pass most DIY jobs skip. A crowned driveway sheds water; a flat one holds it and destroys the surface over time. Target a 2–3% cross slope — that's about 2 inches of rise per 8 feet of width on a standard residential driveway.
To establish the crown with a box blade: start in the centre and work toward one edge, leaving the blade set to deposit material as you go. Then repeat from centre to the other edge. The resulting centre-high profile is the crown. It'll look extreme after you grade it — it won't look extreme once it's driven on a few times and settles.
Final pass with the rear drag board on the box blade, or a dedicated land plane pass. The goal is a smooth, consistent surface — not perfectly smooth like asphalt, but no peaks and valleys that will pond water or create jarring transitions. Keep speeds moderate; trying to go fast on the finish pass produces washboard.
The grading itself is only half the drainage equation. Check these:
Culverts. If there's a culvert at the road approach, confirm it's not blocked. A buried culvert with 3" of sediment in the bottom kills drainage for the entire lower half of the driveway. Dig it out before you grade — otherwise you're just moving the problem around.
Ditch grade. The side ditches need to drain toward the road, not toward the property. If your ditch runs uphill, water from the road will migrate back up under the driveway. This is common on driveways built on lots where the road was cut below the natural grade. Fixing it properly requires a surveyor and sometimes a culvert relocation — but at minimum, don't let gravel fill in the ditch during your grading passes.
Top of grade vs bottom. The top of a sloped driveway doesn't need the same crown as the bottom. At the top, a cross-slope of 1.5–2% is enough. At the bottom, where runoff concentrates, 3% or more. Grade accordingly — don't treat the whole driveway as uniform.
Spring grading in Canada is different from fall grading because you're dealing with heaved material. Frost can push gravel 2–4 inches out of position over a single winter, concentrate it in the tire tracks where the surface compresses under load, and create high-centre conditions where the crown has become a hump rather than a gentle rise.
Wait until the ground is fully thawed before spring grading — usually 2–4 weeks after daytime temperatures are consistently above 5°C, depending on drainage conditions. Grading while the subbase is still partially frozen produces a beautiful-looking surface that immediately begins to heave and distort as the freeze releases. You're doing the work twice.
In Alberta and Saskatchewan, the freeze-thaw cycle can be dramatic enough that late April grading is ideal — the frost is out, but the surface hasn't yet dried and hardened enough to resist the blade. The window is real. Miss it by 3 weeks and you're grading hardpack instead of workable material.
If the driveway has lost significant depth — more than 1–2 inches across the surface — grading alone won't restore it. You'll be redistributing thin material over a bigger area and the driveway will still be undersized in depth. Standard recommendation is 4–6 inches of compacted gravel base (typically 3/4" crushed) for a residential driveway, with a 1–2 inch topping of finer material like 3/8" chip or crusher dust.
For a typical 200-foot by 14-foot Canadian driveway, restoring 2 inches of depth requires roughly 12–15 tonnes of gravel. Price varies by province and distance from the pit — budget $25–45/tonne delivered in most regions as a starting point.
