For those who have a MYMERTIA or MYMESIA stone picker and have a lot of small stones in their fields, JYMPA has developed the HALLEY stone windrower.
This is a helical mill with 64 easily interchangeable tines which, driven by the tractor’s power take-off, allows the small stones on the surface of the soil to be moved to one side, forming rows of up to six meters wide. These stones are then collected in a few passes with a MYMERTIA or MYMESIA stone picker.
