I just got done modifying a DMI 30' machine for a neighbor to put dry fertilizer on in the fall. He pulls a flexi-coil air cart behind it, hasn't used it yet, but I can let you know. Other then that, when I was working on it, it seems to be built really well, I know its heavy, I even had to pry out how thick of steel they use for it (they never did tell me). But it will last.
