I currently have a backhoe attachment for my mini skid (Ditch witch) and I am consistently getting jobs to tile in downspouts whenever I do a renovation of someones property. It looks like this. Now it does a great job digging them but you get big chunks of grass and soil that needs to be broken up and relaid over the trench. You also have to turn the machine to dump each scoop which tears up the grass. Is a dingo trencher worth it? They are about 3 grand used..
