At least on USA-style "cylinder" (here called "reel") mowers the engine
usually drives a countershaft through a clutch, the countershaft drives
a chain driving the reel and the reel drives the wheels through pawls
pinions and ring gears at the ends of the reel shaft. At least that's
the norm on traditional consumer reel mowers circa 1960.

Fancier greenskeeping mowers sometimes have separate drive for the
reel and wheels, but I suspect you'd see the difference easily.

The clutch is rarely a disk type, much more often it's some kind of
belt tensioning arrangement, either an adjustable idler pulley or
split sheaves that can be tightened up to drive the belt.

What you're describing sounds like a loose belt or belt tensioner.

Just out of curiosity, can to post a link to a photo or diagram?

The diagrams for that particular mower are readily available online with a
Google search. That is what I based my S.W.A.G. upon.

Example:

That's _much_ more complicated than I imagined it would be. I can't even
_find_ the clutch....

As best I can tell it uses belt tensioning to provide the clutch action. It
would be much easier to tell what is going on if one had the mower with the
side cover removed.
