Abstract: An aeration machine 10 comprising a drive mechanism 16 connected to sets of tines 18 by a vibration absorbing linkage arrangement 34. The arrangement 34 enables the tines 18 to remain vertical when extending into the ground thereby avoiding elongation of the holes formed thereby. The aeration machine includes a linkage arrangement including a vibration absorbing member. The vibration absorbing member comprises a first part located at least partially within a hollow housing and is held within the hollow housing by a plurality of resilient members.
