WOW, What a machine! Seems like its double my previous LESCO/Echo backpacks output. Pipes are bigger. No more curved tip at the end of the pipe, just a straight 2 3/4" series of pipe extensions. Echo said that it wanted to push the tube backwards into the ground at full power with the curved tip. I was just out in my driveway playing push the brick around. I'll let everyone know how she holds up.
