No expert here, but it looks like there was a tensioning idler pulley in
that black plastic part that sort of "sandwiches" the belt. The marks for
it's axle (pivot) bolt head (or nut) seem to still be evident. Perhaps there
was no pulley on the motor shaft, the drive just using friction on the shaft
itself, with the help of the missing idler pulley? Does the self-propel
control lever or bar move this black plastic part? Parts breakdowns are
easily found on the internet for most machines, if you have the model
number.

That's true, Oh well, sounds like a replaceable part, off to the mower
shop tommorow.
Thanks!
