Subsoiling consists of breaking up the compact, more or less deep layers of soil. It is usually alternated with hoeing, but unlike the latter, it does not turn the soil, but breaks the clods.
Tractor rippers for drainage with tines does not change the succession of layers, as it does not cause turning of the tilled soil. This robust machine, once attached to the tractor through the 3-point linkage, allows subsoiling (or scarification).
The driving force required for a ripper for drainage is generally lower than for a plough. This makes it possible to process almost twice the surface area in the same amount of time. The machine structure is extremely compact, making it suitable for working on all types of terrain.
The tempered steel chisel is replaceable and reversible. This machine can also be used to position an irrigation pipe: the tine will create a furrow where the pipe will be placed,by passing through the channel on the back of the machine.
