ABSTRACT:
A combined digger and compost compacting assembly comprises a digger unit and a compacting unit. The digger unit has a drive shaft which includes a plurality of outwardly extending digger tines for digging into the compost in a mushroom bed as the assembly is moved longitudinally from one end of the bed to the opposite of the bed. The compacting unit includes at least one roller for compacting the compost after the digging tines have dug through the compost. The digger unit and the compacting unit are detachably mounted together for joint movement during the compost treating operation. The units can be separated from each other and moved independently of each other to a different mushroom bed after the compost treating operation has been completed.
