I have an old Craftsman 42inch machine that refuses to disengage the blades; in other words, the blades keep spinning, even though the blades have been put in the disengaged position. What needs to be replaced?

The lever has worn out....thus it is not locking up immediately when fully disengaged. You'll need to trace down the lever right down to the blade mechanism and then you'll notice a fork shaped part that shows signs of wear....very common on craftsman riding mowers.
If the machine has a manual blade engagment, there is normally a small brake block that presses against the upper blade pulleys to slow and stop them, these may need replacing, if not then the drive belt may be dragging in the pulleys
A very common problem since mowers were made noise compliant, to collect grass you need draught, this is produced by putting a large wing on the ends of the blades and having a high engine speed, unfortunatly large wings and high engine speeds mean high noise, so today the wings are very small and the engine revs low, this leads to low draught and grass blockage, you need to keep the under side of the deck clean and free from old grass clippings, make sure the machine is fitted with collection blades, not mulch blades, i cannot tell you to increase the engine revs, however if for some unknow reason the engine were to start reving higher it would help.
If this is a manual engagment system all the lever does is to pull a jockey wheel into the back of the belt to tention it thus starting the blades to turn, so either the cable is jammed that pulls the jockey wheel in, or the jockey wheel arm is seized and needs freeing off to allow the jockey to to move to the relaxed position.
