Do not think of mowing right now. 2 things you need to deal with, look how good it looks before hunting season.... if dead or bad, convert to something different. If ok, great. then, how do you make it top notch for next year?... Soil sample, apply proper fert & lime and I rarely see a situation where you wouldn't wanna frost seed more. If clover is all you want, you're done. If you get caught up in food plots & making a proper management plan, you'll need to think rotation, read dbltree link & join the club of habitat-rehab needing folks.
