Does anyone have experience with duckbill-type earth anchors for
row-ends in trellis orchard or vineyard?
Compacted glacial till is a common feature below about 18-20 inches
here. I am looking for anchoring against
possibly as much as 2000 pounds force. Can aluminum duckbills be driven into
glacial till? Does galvanized cable
rust out after a few years? Other important observations? I didn’t mention
that the soils here are abundantly
supplied with a wide range of stone sizes and types.
