Quick verdict
A hundred 3.3 inch polypropylene pegs with a hook for the wire and a cross-ribbed shank that grips the soil, for pinning robot mower perimeter and guide wire flat until the turf grows over it. Shorter than the long barbed pegs and stiffer, they suit firmer soil where a long peg hits stones and snaps. The hook holds the wire against the ground without cutting it. Keep them for straight runs and use closer spacing on curves.
Strengths
- Cross-ribbed shank grips firm soil
- Short 3.3 inch peg drives where long ones hit stones
- Hook holds wire flat without pinching
- A hundred covers a medium lawn
- Heavy-duty PP does not go brittle in a season
Weaknesses
- Short peg holds less in very soft wet soil
- Plastic still snaps on a stone
- Pegs are temporary until the grass grows over or the wire is buried

Pegs for Ground That Fights Back
Long boundary pegs are right for soft soil and wrong for firm or stony ground, where they meet a stone two inches down and snap. QWORK’s pegs are 3.3 inches of heavy-duty polypropylene with a cross-ribbed shank that grips in a short depth and a hook for the wire, a hundred to the pack, for robot mower perimeter and guide wire.
This review is based on the listing specifications and on how short ribbed pegs perform in firmer lawns generally. We have not used these pegs ourselves.
Short and Ribbed
A short peg needs grip to hold, and the cross ribs along the shank give it. In firm loam or clay the ribs lock in and the peg stays flat. In very soft, wet soil a short peg holds less, and that is where long barbed pegs belong; many installs use both kinds along one loop.
Spacing
Seventy-five centimetres on straight runs, 30 on curves, one at every corner and extra pegs where the wire crosses a hollow so it lies in the dip rather than bridging above it. The mower’s wheels catch any wire that stands proud. A hundred pegs covers a medium lawn or tops up an installation.
Driving
Set the hook over the wire and push the peg in by hand or tap it with a rubber mallet until the hook meets the soil. Never hammer the hook onto the wire. If a peg meets a stone, move it an inch; forcing it snaps the shank.
After Installation
Grass grows over the pegged wire in a few weeks and the turf then protects it. Where beds are dug or lawn edges are cut, burying the wire with an edger is the permanent answer.
Who Should Buy It
- Robot mower owners with firm or stony soil.
- Anyone topping up a short install kit.
- Installers pegging guide wire across a lawn.
Common Owner Complaints
Lifting in very soft ground. Use long barbed pegs there.
Technique Tips
Peg corners first and pull the wire taut between them before filling in the straights, so the loop follows the line you planned rather than the line the wire wants. On a slope, peg from the top down so the wire does not creep. Keep a dozen spare pegs with the repair kit; the first season always needs a few more at the places the mower lifts the wire.
Care
Pegs left in the lawn are mowed over without harm once the grass has grown through. If the loop is lifted for a change, pull the pegs with a twist and they come up clean for reuse.
Alternatives to Consider
The Auto-Mow 100-pack barbed stakes for soft soil. Metal U-pins for stony ground. Burying the wire with an edger.
Verdict
For firm ground, short ribbed pegs hold a loop flat without snapping, and a hundred of these is good value. Space them to the manual and push them in by hand.

QWORK 100-Pack 3.3 Inch Heavy Duty PP Plastic Boundary Wire Pegs for Robot Mower Perimeter Wire FAQs
Short ribbed pegs for firm or stony soil where long pegs break. Long barbed pegs for soft wet soil where a short peg lifts. Many installs use both.
Every 75 cm on straights, every 30 cm on curves and at every corner, and extra where the wire crosses a dip so it does not bridge above the soil.
The hook is rounded. Push the peg in rather than hammering it onto the wire and the insulation stays whole.
Yes. Guide wire is the same gauge and is pegged the same way.
