THE EARTH ANCHOR HAND TOOL IN THIS VIDEO IS ON EBAY. COM
Look for "Earth Anchor Hand Tool".
This video shows how to manually install mobile home earth anchors by hand using the Earth Anchor Hand Tool. The Earth Anchor Hand Tool let's you install a 4 foot helical anchor into the ground using just a socket and wrench instead of an expensive earth anchor machine. With the Earth Anchor Hand Tool, you can install anchors using the inline installation method, where the tops of the anchors are slanted at a 45 degree angle toward the I-beam under the trailer. The inline method gives the anchors more holding power than the vertical installation method used with the machines. Also, the inline method doesn't require using stabilizer plates.
Installing anchors by hand makes more sense if you are only occasionally installing anchors, because it saves the cost of buying or renting an $800 machine, or hiring a contractor.. Even if you have a machine, there isn't enough room under the trailer for a machine to install anchors slanted toward the I - Beam. That's why anchors are usually installed vertically outside the trailer, so they can use a machine.
This video was made while the ground was still frozen, so we we dug a starter hole 12" deep. The starter hole helps the anchor start drilling into the ground, and also makes sure it goes in at a 45 degree angle. In warmer weather, when the ground is soft, a starter hole is not needed,. To make the ground even softer, you can pour water over the ground.
I would say that anyone in reasonably good physical condition should be able to drill an earth anchor into the ground by hand in about 15 minutes. Installing earth anchors by hand saves you the cost of buying a machine, or hiring a contractor, and it also gives you a good workout that can save you money in gym fees..
