Propagation by seeding
There will be many different opinions on this, most of us have methodology that has worked well for us in the past. For the last 27 years of my lawncare career I have seen " seeding " services morph from one extreme to the Next.

How did it become a service considered for uniform establishment of a turf stand??...
The answer / marketing by big companies that sold the service on that very premise and distorted the Agronomic principles of beneficial services.

I prefer a land pride 38" PTO driven seeder behind a tractor for most of the open work, then utilize the smaller ones for the trim and clean up.
Success cultivating depends on timing, proper seed selection, equipment, and knowledge in which method suits which situation as well as weather monitoring.
