Apparatus And Method For Aerating Soil

摘要

A soil aerating apparatus movable along a soil surface in a first direction during soil aerating operations comprises a frame assembly and a plurality of reciprocating arm assemblies. Each arm assembly comprises a tine holder for retaining a tine, an upper arm pivotally attached between the tine holder and the frame assembly, a lower arm pivot attached between the tine holder and the frame assembly, wherein the lower arm is positioned below the upper arm, and a drive arm pivotally attached between a crankshaft and the lower arm. In an embodiment the crankshaft comprises a plurality of central shaft sections and a plurality of eccentric shaft sections, wherein each eccentric shaft section moves in the first direction when each eccentric shaft section is positioned above the plurality of central shaft sections during soil aerating operations.
