I "think" most of the 7000 drills ended up back at Flexi-coil in S'toon and were tore down and scrapped out??
I do KNOW that the slim design with regular shank/opener (not a para-link/ independent opener) were a poor machine.
They had lots of trouble getting penetration and even placement.
Everyone I know of that had one switched to a bourgault 5710 or upgraded to a BG or seed twin drill.
I think the newest independent versions in Case-IH and NH paint have major improvements and work well.
I like the slim transport idea but have no personal experience using one.
