Last September I wrote about the mower belt slipping off the drive
pulley on my Craftsman lawn tractor. I discovered the solution quite
by accident while I had the mower off for the winter.
There are two brake pads that hit the blade pulleys when you disengage
the drive; these stop the blades' rotation instead of allowing them to
keep spinning after disengagement. Both pads had deep groves worn
through them, down to the metal on which they were mounted. This was
just enough extra play to let the belt slip. I replaced both pads and
now the belt stays put.

No special skills required. First, remove the mowing deck from the
tractor, which is fairly easy and described step-by-step in the user
manual. The pads are stuck on pivoting metal bracket thingies which
can be removed with a socket wrench; you buy new bracket thingies and
bolt them back on. Fairly obvious what goes where, but there's a
connector rod between the two that complicates things slightly. I did
it without blaspheming or throwing tools around the basement.
