I do it all the time, also with an 84” model. I typically spray a couple weeks ahead where I want to plant. I also plant wheat into existing clover in the fall. I run the disk gang where it disturbs about half the soil surface, leaving the other half uncut. I think it actually invigorates the existing clover. As said above, it is not a no til drill. But, it still does a great job with a little forethought. It also does some things a no til drill doesnt do, like smooth the soil surface - like if you have hog root. It is also a great piece of equipment to use on smoothing ruts and maintaining trails. I plant about fifty acres a year with mine - from clover to soybeans.
