Around here, the contractors working roads plant as they complete the road projects, no matter what the time. They run rippers a coupla inches deep (some til, but most don't) then seed. Then they blow a mulch (Hay) mix over it. Finally, they run a straight bladed disk over it to push the hay/seed into the ground.
It's not lawn, but they generally get good results planting K31 fescue.
