Also can you put in 3-4 inch pipe with a trencher? If so what models.
Could be compaction in the top millimeters sometimes.
Also, along the lines of surface compaction related to drainage, I don't think most homeowners or lawn services aerate at the right time of year, or enough. Many services try to do it to serve themselves to make money, not to serve the soil. That's the case if they aerate when soil is so soft that walking and mowing easily close the holes again.
When the soil is firm enough, I think it should be done twice over ... maybe more.
