I think you are on the right track thinking of spring strip till for HEL ground in areas where pure notill is not a viable option.

There are a couple points to be aware of however:

1) CULTIVATORS are designed to operate ON the tractor tire spacing = between the rows, where you would be cultivating.  STRIPTILL on the other hand is done OFF of the tractor tires as a planter bar is. The pivot points and about everything else you can think of on a cultivator bar is usually welded in exactly the wrong place on the bar when trying to mount any type of strip till units. Planter toolbars are much better places to start a strip till machine than a cultivator bar.

2) For SPRING strip till, especially farther north, in many soils you are better off using a coulter-type rather than a shank-type strip till machine. I think it is interesting that Orthman, long the "deep shank" strip till people, now offer a conversion kit to convert their shank type strip till unit to coulter type units. Be aware of the risks of spring planting directly over a spring made shank-type strip with a real hot band of concentrated fertilizer right at the bottom of that often still open (below the surface) slot.

Best of luck,
