The Sovema new model SQ circular rotary ditcher, is designed to make surface drainage ditches using your own farm tractor. Both models 20” and 26” are equipped with parking stands, for easy hook-up and disconnection. The standard 20” 6-paddle impeller on the SQ 20 is ideal for running in extremely trashy or wet conditions, while the 26” 5-paddle impeller moves more dirt per pass, making a wider shallower ditch.
