Craftsman Mower Deck Won't Disengage

I recently bought a used (approx 12yrs old) Craftsman Riding Mower with a 15.5 HP Kohler engine and a 42" mower deck. The problem that I'm having is that the blades engage soon after I start the mower. This is with the "Attachment Clutch lever" in the "Disenaged" position. I have replaced the belt (as per catalog part#), pulley brakes, and confirmed that the clutch lever and assembly are working properly. There seems to be sufficent slack in the belt, however I have noticed that the belt seems to "catch" on the main drive pulley soon after the engine starts, and then forces the mower deck into action. Is this a know issue with these type of mowers?

Is this craftsman deck actuated via cable or linkages?

I'd say the belt guides needs adjusting. With the belt engaged (with the engine not running) the guides need to be 1/8"-3/16" away from the belts backside.

Thanks for the responses. V8-Springs are in place, Cheese - Linkages, Puey61-I noticed that the belt gets sucked way into the Main engine pulley (approx. 1"-1-1/2") and binds. Is the pulley width adjustible?

The pulley width is not adjustable, but if it has a bent spot on a sheave, it will cause your problem. Otherwise, since you have the linkage type, there is an adjustment for belt tension on the rod that engages the blades under the mower frame where the rod connects to the engagement arm that runs up to the dash. Are you sure you have the correct belt? This one probably takes either a 144200 belt, or 144959.
