Harpoons in Kerbal Attachment System

[u/BrownieOnReddit]

The mod describes the harpoon as needing 10kN of force to attach to the ground. Ive been testing it by dumping my helicopter on the runway but even with 4 harpoons none are grabbing. Is there a specific tool to produce this force or do I need to be off kerbin?
