Helical ground anchors for vineyard trellis systems

Helical ground anchor. The smart solution for flat terrain

Helical ground anchors transfer the tension of every wire in the row from the end post into the soil. Made of galvanised steel, they screw directly into the ground like a corkscrew, disturbing almost no soil.

When to choose a helical anchor

The helix is the practical choice on flat terrain without rocks or deep roots, and when retrofitting an established vineyard where excavation would damage existing root systems. It performs well in firm soils, poorly where large stones can deflect the blade.

Compared to concrete base anchors, the helical model installs faster and needs no heavy machinery. It handles lower peak loads, so on long rows or heavy canopies the concrete base remains the safer option. In softer ground, an anchor plate spreads the load further.

Sizing the anchor

Wire tension on a vineyard end post commonly reaches 400 to 1,500 kg, depending on wire count and gauge. The anchor must match that load and the soil type. For the full method, see how to anchor grape trellis posts.

Helical anchors pair with end posts in Mini Strong 56 x 46 and Strong 68 x 56 mm sections. See all trellis anchors and the full range of vineyard supplies.
