Yard Guys- How do you Prep for Grass?

Great suggestions. We just cut down/pulled out the dead, but still standing, weeds today. I'll wait until spring to apply weed killer. Then rent a rototiller. WevWe been thinking about buying a lawn tractor and really need to with .8 acre to mow (although the wife likes the exercise of pushing a mower, trouble is we're not getting younger!).

I know we didn't want the expense of sod, but I hadn't thought about spray grass seed, thanks @Bad Sport. Will definitely look to do that.

Would it help to rototill this winter or just wait until spring?
