This invention is a soil backfilling device mounted on a vehicle used for producing a plurality of aeration holes in a single operation. A control is provided for metering the backfill media into a plurality of metering tubes and a second control is used for selectively disbursing the backfill from the metering tubes into the aeration holes. The backfilling device is shown in conjunction with one type of multiple aeration hole forming machine but, of course, it could be used in conjunction with other machines accomplishing the same results.
