The Tri-Anchor anchors 3 points into the ground to spread the ground purchase. Simple to set up, just stand on it and dig the 3 points into the ground. The points pull into the ground further when the irrigator weights comes on.
The Tri-Anchor is great in places when there is nowhere to anchor to:
Paddocks that are longer that the wire rope
To take the stress off fence posts
On hump and hollow paddocks you can anchor on the centre of the hump when an in-line post isn’t available.
