I haven’t had problems with clearance, except for the very first hold down on one of my mowers (Deere #5, IH #100, Dearborn) don’t remember which one, part of the knife head so I rivet the two sections? that run under that. The cast knife head connection (thicker causing clearance problem) don’t remember would have to look. But for all the rest I use the bolts. I might be able to swap out that first hold down for a high arch one, but its not a big deal to me.

I've thought about getting some of those bolts for replacements/repairs. Cousin runs them on grain header--rocky land and soybeans are a bad combo. Will they clear standard "hold downs"?

I will still replace sections on a knife, whole replacement knife is nicer, but I don’t rivet them anymore I use section bolts. First used the bolts on combine sections and thought why not mower? The nut sticks up a little more than rivits, but I don’t have any problems mowing my alfalfa/grass hay.

Sickle mowers can be a pain.

First off keep anything you don't want to cut from the area in between 
the guards--especially when raising and lowering the blade/working on 
mower. I always grab by the back of the blade or the heavy cast piece 
out on the end.

Second, run the sickle mower for edge/ditch trimming first. They don't 
like thatch/debris form rotary mowers, tend to bunch up right where the 
blade bolts on. Also if you head into a field that was previously 
overgrown and has been bushogged while leaving large clumps, you are 
going to hate life as the blade will choke up often. Sometimes you can 
hold the blade up or install a clipping wheel on the end to manage this 
situation.

Third, they either are in mowing condition, or not. Unlike a rotary 
mower with dull blades that you can limp along with, these things tend 
to be all or nothing. One broke guard or section and it just plain won't 
work. I have found it cheaper and easier to NOT put new ledger plates in 
the guards replace the whole assembly. Also when the blade is worn out, 
I order a new assembly instead of changing all those sections. Lot of 80 
year old guys will talk about how easy it is to do, but they aren't 
doing it. Also they are basing it on their memory of doing it in 1975 
when parts were more pricey, Its not that bad to buy a complete blade 
sent to your house ready to change out. FWIW, I have one of those tools 
you brad rivets with, works great if you break a section and want to fix 
it in the machine.

Here is where I get my parts from if I have to "overhaul" a cutterbar. 
Last one I did was a 7' IH two years ago. https://www.cuttingcomponents.com/

Any kind of grass/weed/vine these things do great in. Small trees much 
more than a couple feet tall and you risk breaking a section and 
possibly a guard---or even the blade. Be sure to ask for whatever spare 
parts the guy has to go with it.

You should be able to adjust the pitch of the blade, but more than 
likely its already set up OK. I'd try it first.

I'm sure you know, but to save some cussing--if one of the guard bolts 
has to be pulled off and the square doesn't want to stay in the  hole 
(think plow bolt), don't use your thumb to hold it in!!!
