All loaders are not equal. My Great Bend 330 Loader frame does a real nice job of blocking the tray. I imagine some of the thought/design process centered on access to engine. Frame is pretty much at same height as hood so it interferes very little for most of the engine access (filters/starter/etc.) and I can always remove the tray if I need to get to the top of the engine for injectors or anything else up there.
