You got some right answers as far as what the slots are for, but to make the adjustment, that's another thing. Take the unit off the tractor, remove the 1/4 inch bolts, and separate the two halves of the pulley. Typically the pulley has been 'adjusted' with a hammer and punch, which muchrooms the thin material it is stamped out of. grind off the mushrooming, and use emery cloth to get a smooth finish and the two halves should rotate easily when reassembled. A little graphite during reassembly doesn't hurt either.
