hello, we will have to clean up a long abandoned agricultural land, for this purpose we will use a six ton excavator, with the standard bucket we lose a lot of time, they advised us to adopt the bucket rake ripper, ie a wide bucket type rake comb that hollowed out of the ground roots and stones very wide stones, like bucket clean ditches, it costs an eye so we would like to make a rake craft using a bar profiled steel, about fifteen twenty millimeters thick to weld some pieces of steel rod long forty fifty centimeters, some consanguine or example of an example already done in the home by hand, thanks for the attention
