A device for being driven into an earthen surface. The device includes a
lubrication system having a manifold. The manifold includes first
orifices that deliver lubricant to the interior space of the pile body.
The first orifices are spaced around a 360-degree circumference of a
lower end of the device body at intervals no greater than about 50% of
the 360-degree circumference. The manifold also includes second orifices
that deliver lubricant to the exterior surface of the device body. The
second orifices are spaced around a 360-degree circumference of a lower
end of the pile body at intervals no greater than about 50% of the
360-degree circumference.
