I wondered about that hose too, but I have not had any problems with it.
Do you have interference with the left bracket that mounts underneath? My mower linkage does not clear where it passes through the bracket. I cannot have the bracket and mower linkage on at the same time. I contacted Woods about it. They said they had only 1 or 2 complaints and that all others fit ok. They sent me another bracket, but it has the exact same problem.
