Yes, I think this is right, based on my reading of the manual.  It  
says to push in the clutch before pulling up on the PTO engage lever.

I think I don't have this and won't till I get a much newer tractor.

I will ask about this when I talk to the folks who apparently have a  
field full of old implements.  sounds like a one-way coupling or free  
wheeling unit.  The helicopter I flew had one at each engine input to  
the transmission so a dead or idling engine would not load down the  
rest of it.

I wonder if it's a thing you can get to put onto a brush hog that does  
not yet have it.

I will most likely be looking for an old used but serviceable one.  I  
can replace bearings, get welding done (two doors up the road) and in  
general do mechanical stuff.  Though with the cold weather, I'd rather  
not do too much repairing this season.

Thanks for the guess as the the right size for it. I'd much rather  
take more turns around the field than go looking for PTO gears or  
transmission parts because I pushed it too hard.  The H-4 tractor was  
tested at about 29 horse power (though the manual never says what the  
rated output is.)  The service manual shows the width of the rear  
tires to be 65 inches, so a 5 foot brush hog would cut just about that  
wide.

From what I can see in the manuals, the W-4 I have is the wide front  
wheeled version of the H-4.  The I-4 is the industrial version and  
came with a pulley and a different set of speeds in the transmission.   
(My tractor has the pulley engagement lever, but not the pulley  
itself. The plow frame seems to be in the way where the pulley would  
be, and I'm not sure what I'd use a pulley for, except an emergency  
generator.)
