Verti-Quake

A make of tractor mounted linear aerator, with more than one model. The working widths range from 1.1m, 1.6m, 2.1m and 2.5m. The number of blades on each unit varies from 12, 18, 24, and 30 depending upon the width of the model. The maximum working depth is 250mm, except for the largest 2.5m wide machine, which has a maximum working depth of 380mm. Each model has coulter knives, like curved chisel tines, which are slightly offset. The rotary action of the knives creates a side-ways decompaction of the soil profile; it is manufactured by Redexim-Charterhouse.
