Almost sounds like you have some slippage. Is the clutch adjusted so when it’s engaged the bell is tight up against it?  
 Take a scroll thru the manuals section, I’m sure we have yours in here.

You add tension by turning this trunion, closer to the PTO handle, a little bit at a time.

@gris71 question , how easily can you move that drive belt by hand?  tractor shut off , key in pocket ,collective attachment  drag , from  related bearings , grass build up under deck  , as well as clutch adjustment can add up to very heavy belt drag . the easier it all spins up by hand , should be easy for the drive belt to move it , pete

Also inspect this area and the bracket. There should be a pin holding it on which is common to fail after 30-40 years. If it's not attached correctly you can't adjust enough.

Post a pic of yours so we can see it
