I picked up this odd looking sickle mower and had a hard time finding info out about it. I'm guessing it was made in 1941, since that's what the Briggs model A dates back to. The engine starts right up and runs fine, the sickle engages and functions fine, but I have to do some work on the drive engagement clutch. I did find a brochure on the machine, but I was wondering if anyone has a pic of the drive clutch assembly.

Well, I just figured out what was wrong with the clutch. Somebody tinkered with it and had the fingers way out of adjustment. The clutch engages and disengage fine now. I had another old Firestone Power Tread tire laying around, so I swapped out the bad tire. Those split rims are a nightmare! Anyway, I took it over to some tall grass and gave it a try. The old machine works fine, but I'll have to sharpen the cutter bar and replace one broken rock guard.

I did find a post here by member DB1 regarding one of these sickle mowers. It was on page 6 of the "walk behind of the day" thread. Here are the pics of DB1'S mower.

DSCN2562.JPG I`ve seen 3 of those larger National mowers here in New England, for some reason they aren`t too rare around here. Here`s a picture of their small mower that I was lucky enough to find at a flea market this past summer, it is from the 1940`s and has a Briggs Model N on it. I`ve used it, but the teeth need to be sharpened, plus the tall weeds get tangled up in the cutter drive mechanism. But I like it anyway!

Rustysteele, the smaller one like yours would probably be more useful to me. I did use mine for a bit and it worked good, but it needs some tinkering with. I found a new cutter bar with the same teeth that's new and has been laying on a shelf for years. The owner doesn't know what it fits, so he said that I can have it for cheap. I plan on restoring my sickle mower and use it around the place once in a while. I like the looks of the thing, and I'm a fan of those old hand crank Briggs engines. It fires right up cold, with one or two cranks. The mower is bigger than I thought, and it weighs 260 lbs. according to the pamphlet. The owners father would use it to cut some hay for his horse once in a while, years ago.
National did make a wire grass/weed guard that stood above the cutter bar and would push the weeds forward and away from the cutter bar. There is a pic of the guard in the pamphlet. I see that there are 4 holes in your sickle bar, two at each end. You could fab up a grass guard to keep the grass and weeds away from the bar and shaft assembly.
