We got along just fine w/TC clutches. We had 16 clutches on JD1790 16/32 planter. They were in groups of 2, as you can see from photo. Next yr we'll put them on single rows. We have RTK for differential.

I thought we had a compressor problem, but it was a pinched ground wire. I do wish they used a heavier-duty compressor, especially for the retail price of a replacement ($499) from them.
