Windmill Tower Mounting
-- The whole idea is to get some weight in the ground so the windmill tower does not blow over in a strong wind. Concrete mounting is a good idea.

Tower Mounting: GROUND RODS | IN CONCRETE POST HOLE
One simple way to mount the windmill tower is to use the three (3) Koenders supplied four (4) foot long, one (1) inch diameter steel rods set directly into concrete filled post holes and tightened in the tower leg clamps. In the photo above the mounting technique also levels the tower on a slope.

Another Method: GROUND RODS | NO CONCRETE
In strong winds tower ground rods mounted directly into the ground with no concrete as in the photo above can pull up and blow over -- especially in water soaked sandy soil.

Ground Rods into 3 concrete pedestals

Typical Koenders Windmill Tower Mounting:
Three (3) ground rods | 1 in. diameter steel rods | 4 ft long
The Koenders Windmill tower comes with three (3), 1 inch diameter | four (4) foot long steel ground rods that attach through a clamp on each of the three legs of the tower and can be sledge hammered into clay soil, and the 7/8 inch in diameter clamps are then tightened. If you have sandy soil, or a taller tower you'll need to determine the best way to anchor your tower for your pond site. Some customers have made concrete footing pedestals for mounting the windmill towers at severe wind pond sites.

Windmill Tower Mounting | Using A Compression Anchor
At Tweedy Lake concrete footings were dug, formed and poured.

Windmill Tower Mounting
-- Dig holes
-- Pour concrete footings at the proper tower leg stance distance
-- Position the Windmill Tower legs on top of the concrete footing (without the windmill attached)
-- The Windmill Leg clamps are 7/8 inch in diameter
-- Use 3/4 inch threaded Red Head (Compression Anchors) -- they come in all different sizes
-- At Tweedy Lake 3/4 inch | 8 inch long Red Heads were used
-- Put the Red Heads (Compression Anchors) through the tower leg clamps
-- Accurately mark the proper position of Red Heads through the tower leg clamps
-- Using a Roto-Hammer (or a Hammer Drill)
drill a hole a minimum of 2 to 3 inches deep or more into the solid concrete footing
-- Then put the Red Heads back through the tower leg clamps
-- Raise up the tower -- now with the Windmill and Air Line attached
-- Position the tower properly on the concrete footings
-- Then hammer down the Red Hats and install a flat washer and nut
The way a compression anchor works -- With a flat washer and nut already on the threaded Red Head -- place the Red Head through the tower leg clamps into the hole -- then drive the Red Head down with a sledge hammer until it seats at the bottom of the whole -- then tighten the nut. As the nut is tightened, the compression anchor compresses itself against the sides of the concrete hole and will not pull out.
