摘要

The aerator for ground covered with grass has tines mounted on holders (10). These are attached to levers (8), allowing them to be raised and lowered. The angle of penetration of the tines can be adjusted by moving stops (18) which the holders rest against as they are lowered. This is achieved by moving a slide (25) which is connected to them.
