Some of my clients I do a full lawn aeration on the property, then I pass with my dethatcher, then once all the thatch is picked up, I fertilized and overseed at the same time. It's a BIG boosting package for a lawn in the spring. Usually in spring it's always damp, so the seeds take no time to germinate. You cut the grass a bit shorter than usually before doing that, that way the customer can stay away from his lawn extra longer.
The only bad thing I can see if your mowing your lawn that has fresh seeds, is the seeds might fly away or get displace.
