Careful using the machine on buffalo, it grows on top of the ground and if you go to far it'll remove your growing points.
If you do, set the height on a concrete surface so that the tines only just hit the ground and the wheels take the weight.
Aeration is the real long term solution, that will encourage the bacteria and microbes to break down the organic matter naturally and the plant will get a feed from the bi-products of the process.
