Keith; As a "recy mech"(towie) of many years experience, what is pictured are ground anchors and pins. Plates may be coupled together by the "D" shackles at each end. Each plate when pinned will support a load of 7 tons pull. Used for anchoring snatch blocks, or recovery vehicles during a pull. I have them as part of the kit on my Diamond T. When pins are properly driven into the ground, especially clay, you need a bloody wrecker to pull them out.

Intriguing, received wisdom here suggests the ground anchors were supplied as a plate with 9 pins, 8 being used on the plate and one as an "extractor".

Reputedly, the pins are hexagonal to make extraction easier by using the 9th spare pin as a lever in the pin eye and rotating it to create a now loose(ish) circular hole.

I guess you're saying the theory and practice don't exactly agree. . . . .
