Repairing Lawn Damage from Heavy Equipment Ruts

Contractor's chipper and trucks caused 300 ft of 2-6 inch deep ruts, mashed soil. Contractor's minor repair made it worse. Wind dried mud. Planned to reseed, fertilize, aerate but delayed. Soil soft from grading. The expert advises leveling ruts at the right moisture. Drag an I-beam or chain-link fence behind a vehicle to smooth. Soil too wet clogs, too dry needs power.
