Sow grass in March or wait?

Exactly, a 5-tonner pulls everything smooth at the height of my lawn edges to the pavement. The soil is from the farmer who has a large screening plant.

Then let him leave me a pile of soil and loosen everything up and distribute the stuff with a shovel/rake.

I come from the North, meaning lots of rain and 5 degrees at night.

As I already said: too cold. And once the northern rain sets in, the seed gets washed away. Isn't turf an alternative?

No, unfortunately not. It's not that thick in the wallet anymore. Rolling over could have been done earlier, but it would mean a top somewhere around a 1500€ watch.
