good video, thanks. I've been looking for something like this that tested those tractor supply anchors. I use them quite a bit as I live in hurricane country, but never really knew what they'd hold. An interesting test would be driving 2 in the ground fairly close to each other, pulling one immediately like you did and pulling the other 6 months to a year later after the ground settles and seeing the hopefully large difference.
Thanks for watching! Keep in mind the pulling force required to remove an anchor is *highly* dependent on ground conditions, the angle of pull, depth, and other factors which need to be considered. I would expect to see an increase in holding ability over time as well although I have not tested this. Even anchors installed within inches of each other can exhibit surprisingly substantial differences in holding ability in my experience so a time duration test may not be able to be consistently proven. Pull testing (proof testing) to a target value is essential to be able to have confidence in an anchor's ability to hold a given force. Even then ground conditions can change (ground moisture levels can significantly affect holding ability) which can reduce it so some safety factor should also be incorporated. Many times it's difficult to determine the anticipated maximum loading on the anchors so there are a lot of factors at play and potential unknowns. I plan on doing more anchor testing videos in future to share what was found and help increase general knowledge and application of anchors.
