To make a garden hiller, bolt two angled wings to a handle or frame so each pass funnels loose soil into a straight ridge.
A garden hiller is a dirt-moving tool that mounds soil onto a row. It’s handy for potatoes and sweet potatoes, and it works for garlic, leeks, beans, and any bed where you want a raised row for drainage and cleaner weeding.
You don’t need fancy gear to build one. A drill, bolts, and scrap metal are enough. Below are two builds: a hand hiller you pull like a hoe, and a wider hiller you can clamp to a wheel hoe or a small push frame.
| Build | When it fits | Scrap parts that work well |
|---|---|---|
| Hand V hiller | Short rows, small beds, quick touch-ups | Old shovel blade, angle bracket, hoe handle |
| Hand V hiller with skid | Rocky spots where the tool wants to dive | Flat bar, hardwood block, extra washers |
| Fixed-width push hiller | One crop, one row spacing all season | 2×4 frame, bolts, sheet metal wings |
| Adjustable-width wing hiller | Mixed crops with changing row widths | Slotted flat bar, carriage bolts, fender washers |
| Wheel-hoe mounted hiller | Long rows with a steady walking pace | U-bolts, clamp plate, two steel wings |
| Furrower plus wings | Open a trench, then mound soil later | Narrow point, removable wings, spare bolts |
| Wide “mulch” hiller | Pull soil over straw or leaf mulch | Wider wings, smooth edge trim, light handle |
| Bed-edge hiller | Pull soil back onto a raised bed after rain | Short wings, stiff bracket, compact handle |
What A Garden Hiller Does And When You’ll Use It
Hilling moves soil from the walkway between rows up onto the row. That buries tiny weeds, dries the surface faster after rain, and gives tuber crops a deeper, darker zone to form. In potatoes, many extension publications describe hilling in more than one pass as plants grow, building a ridge over time before bloom.
A hiller saves effort because the wings guide soil toward the center. With a plain hoe you can do the same job, but it takes more strokes and the row width tends to wander.
How To Make A Garden Hiller? With Scrap Materials And Basic Tools
Step 1: Pick The Row Width And Wing Size
Measure the open space between rows and decide how wide you want the ridge at the base. For many gardens, a 10–14 inch base width feels right. Taller ridges usually come from repeat passes, not from one deep cut.
Step 2: Gather Materials And Tools
- Two wings: sheet steel, an old shovel cut into halves, or two plates about 6–8 inches wide.
- Center bracket: angle iron, a thick L-bracket, or two flat bars that bolt into a V.
- Handle or frame: hoe handle, broom handle, or a short push frame made from 2×4 lumber.
- Hardware: four to six bolts with washers and lock nuts; U-bolts if mounting to a toolbar.
- Tools: drill, saw or grinder, file, wrenches, marker, tape measure, clamps.
Step 3: Set The Wing Angle
The wing angle sets how hard the hiller pulls and how much soil it moves. A good starting point is a 35–45° opening from wing to wing. Lay both wings on a flat surface, set the bracket between them, then mark and drill holes so both sides match.
Build 1: A Hand V Hiller You Pull Like A Hoe
This build is light and quick to tune.
- Cut two matching wings. A handy size is about 7 inches tall and 8 inches wide at the back. Taper the front edge and round corners.
- Drill the wings. Drill two holes per wing, set back from edges.
- Make the bracket. Cut 6–8 inches of angle iron or a thick bracket. Drill matching holes.
- Bolt it together. Use washers on both sides and tighten lock nuts.
- Attach the handle. Bolt the handle so the wings sit flat when you stand upright.
- Smooth the edges. File burrs and add a small bevel on the leading edges.
Depth control with a simple skid
If your hiller dives, bolt a flat strip under the center as a depth shoe. A short hardwood block can work as a skid too. Set it so the wings run shallow on the first pass.
Build 2: A Wheel-Hoe Or Push-Frame Hiller For Long Rows
For long rows, mount the wings to a crossbar and clamp or bolt that bar to your tool.
- Make a crossbar. Use flat steel bar, or a straight 2×4 with a thin strap where bolts pass.
- Drill wing holes evenly. Mark a centerline, then measure out the same distance on both sides.
- Add slots for width changes. Cut short slots and clamp with wide washers.
- Mount to your tool. Clamp to a wheel hoe toolbar with U-bolts, or bolt into a push frame so it stays square.
- Add a skid plate or small wheel. Depth control keeps the pull manageable.
Tuning Your Hiller So Rows Stay Straight
If you’ve ever asked how to make a garden hiller? and ended up with lopsided ridges, tuning is the fix. Small changes beat a rebuild.
Work Soil That Breaks Apart
If soil smears, it’s too wet and wings pack it into slabs. If it’s powder-dry, the ridge falls apart. Aim for soil that holds together when squeezed, then breaks apart with a tap.
Set Width First, Then Build Height In Passes
Keep wing width steady and build height over two or three passes. Potato notes often describe hilling more than once as stems grow, keeping tubers under soil and out of sunlight. See Growing potatoes in home gardens and Potato production for timing examples.
Stop Side Drift
- Check symmetry. Measure wing tip to centerline on both sides.
- Square the handle. A crooked handle steers the tool.
- Back off toe-in. If wing tips point too far inward, one side bites harder.
Lighten The Pull
If it feels heavy, the V is too steep or the depth is too deep. Flatten the wings a bit and take a shallow first pass. For wheel hoe setups, raise the mount so wings ride higher, then lower in small steps.
How To Use A Garden Hiller Around Plants
On the first pass, stay shallow. You’re shaping the row and cutting weeds in the path. Keep the wings centered. If plants are already up, keep soil off tender top growth and mound around stems instead.
For cleaner ridges, do one pass down each side of the row. Two side passes pull soil inward evenly and keep you farther from stems.
Mark A Guide Line For The First Pass
If your rows snake, your hiller will follow. For the first pass of the season, stretch a string between two stakes and walk the hiller just outside the string. Keep your eyes on the end stake, not on the wings. That small habit keeps the tool tracking straight. After that first straight pass, the shallow track becomes your guide, and the next passes fall into place with hardly any steering.
When you reach the end, lift the tool before you turn. Turning with wings in the soil makes a gouge that steals soil from the ridge. If you run drip tape, keep it centered on the row top or tucked a bit off to one side, then hill from the opposite side so the wing edge doesn’t nick it.
| What you see | Why it happens | What to do |
|---|---|---|
| Soil piles on one side | Wings are off-center | Re-measure, add washers, or re-drill the bracket |
| Tool skips and chatters | Soil is cloddy or too dry | Water lightly, wait, then pass again |
| Tool clogs with slabs | Soil is wet and sticky | Wait for crumbly soil, widen wing opening |
| Ridge collapses fast | Rushed, deep first pass | Build the ridge in thinner layers |
| Hiller dives deeper | No depth limit | Add a skid shoe, raise the mount point |
| Pull feels heavy | Wings too steep, depth too deep | Flatten wings, reduce depth, add a skid |
| Plants get nicked | Working too close to stems | Hill from the sides, narrow the wings |
| Wings bend on rocks | Thin steel, no stiffener | Add a rib from flat bar or use thicker steel |
Care, Storage, And Quick Safety Checks
Knock off dirt after use and let the tool dry. Wipe metal with light oil to slow rust. Tighten hardware after the first session since new holes and bolts settle.
Before each session, check for burrs, loose nuts, and handle cracks. Wear closed-toe shoes and eye protection when cutting or drilling metal. Clamp work pieces so they can’t spin.
One-Page Build Checklist
- Measure row spacing and pick a ridge base width.
- Cut two matching wings and round the corners.
- Set wing angle and mark holes on both sides.
- Drill wings and bracket, then bolt the V together.
- Mount a handle or crossbar and square it to centerline.
- File burrs and add a mild bevel to the leading edges.
- Test a short row, then tweak width, angle, and toe-in.
- Add a skid shoe if the tool dives or pulls hard.
- Store dry and wipe metal with oil.
Build it, run two short passes, then tune the wing angle. If you hit a snag, change one thing and test again. If you’re still wondering how to make a garden hiller?, the answer is two wings, one solid bracket, and a setup that stays centered.
