forward link 310 is rotated so that spikes 315 are driven into the ground as the spikes of link 310 are driven into the ground coils 316 of link 310 are moved to the ground segment 313 of link 320 which is disposed through coils 316 of link 316 is thus moved closer to the ground causing link 320 to rotate such that the planar portion 317 of the link 320 is positioned tangentially to the wheel 500 and spikes 315 of link 320 are pointed closer to orthogonal to the ground as shown in fig5 b as portion 317 is planar wheel 500 may easily continue rolling once spikes 315 of link 310 have been completely driven into the ground the wheel 500 then rolls over the link 320 and forces the spikes 315 of the link 320 into the ground similarly as the spikes of each link are forced into the ground the planar portion 317 of the subsequent link becomes tangential to the wheel 500 and spikes 315 of the subsequent link are oriented closer to orthogonal to the ground since all the spikes 315 are electrically connected by the ground strap 330 of fig3 the equipment is grounded when the ground strap.
