I didn't think about that before, but after 5 seconds of looking at it, it all seems obvious. I always give the mower a washdown and a blow off after use, and these would actually be a pain in the rear in that regard, unless there are sections that allow easy points to stick the hose in without getting it on the engine itself.
The slightly lower price V40 Mustang of the same period I put up here recently would be your dream catch then!
Looks great and easier to clean.
