Very interesting indeed. Super find. Thanks Tabora. FWIW my mower is labelled "commercial" and it is powered by a 5 hp briggs. Poking around the web I have seen no pictures of a unit with that label. Rather in that spot the say "Self Propelled " These behind the scenes letters cast light on that. The blade on mine measures 20 inches, 16Here's an interesting series of documents from 1982 about NOT certifying the Sarlo 416 & 416SP as consumer products...
Ya, from the reading you provided, it would seem so. So maybe my machine was a requested build from a landscraper, or farm, etc. Paper did state they built to order, just up-motored a 416 chassis?? Does say commercial. One other thing different on mine that I don't see on others from google image search is the drive uses a bale (or whatever you call it) at the handle bars, not a lever. Anyway, its all fun.That's interesting... My understanding was that the 416SP was 4HP, 16" wheels, Self Propelled.
right? there is a new crack extending from a old repair at a place which supports the wheel drive mechanism. I think those egg shaped wheels put an undo stress on it. Engine bolts were not tight either and one is clearly worn as well. A clattering collection of contiguous junk! Like the Tin Man in Oz.
Not boring at all, love these type of threads, especially on a machine I have never seen before or will probably never see again.I got the engine off today. If I continue to spend one hour a week on this it will be ready by fall. The engine sits on a cradle that is the part cracked, so that comes off for welding. The cradle is bolted in through slotted holes so the whole engine slides to provide for blade belt tension adjustment. A few boring pics below.
