[Farmall] overrun clutch question

[DBigdog]

Lisa,
    A slip clutch and an overrun clutch are different things.  The slip 
clutch will "slip" if the implement binds up and protect (hopefully) the 
drive system.  An overrun clutch allows the implement to coast when the 
input shaft (pto) is running slower than the driven shaft (mower).  It has a 
ratchet mechanism that allows force in one direction only.  Your H would not 
have that feature built in.  Adding one would not affect the operation of 
your sicklebar mower.
    Overrun clutches are available at places like TSC.

Hey all-

I am not tractor savvy, so excuse if this is a really dumb question ;-)

#1 I just bought a used "Bush Hog Squeeler" pull type mower to run off my 
1943 H. I've read  recomendations to use an overrun clutch on the PTO when 
running these kind of implements on old tractors. The Bush Hogs manual says 
that it has slip clutch between the connector shaft and the drive housing. 
Is this going to stop the implement from  driving back down the PTO and 
running my trans.? Or is it something totally different?

#2 how would I tell if my tractor already has a overrun clutch on it's PTO?

#3 I also got a JD #5 sickle mower -- if i need/get an overrun clutch for 
the tractor will it effect operating the old sickle bar? ( I  have manual 
for that  says it has a slip clutch to protect it's shaft to drive mechanism 
blah blah blah)

#4 if I need to get an overrun clutch for the H- where's a good place to get 
one?

I have  old famah  neighbors that babysit me and my learning curve with the 
old H ;-) ....but they don't seem to know anything about this overrun clutch 
stuff-- they didn't think it was anything to worry about? I haven't run 
anything yet
