Small Engines (Lawn Mowers, etc.): Sears Riding Mower, mower blade, seat safety

Question
I have a Sears riding mower that was running fine and all of the sudden the engine died when I let out the clutch or engage the mower blade.  it starts fine and runs as long as the clutch is in or the mower blade is disengaged.  The seat kill switch had been bypassed by the previous owner.  I found the switch that kills the engine from the mower blade engagement lever.  Any help would be appreciated

Answer
 Hello Jaime:

 ReCheck the Seat Safety Jumper. Go to this Addy http://www3.sears.com/ and Click on teh Lawn Equipment Box. Then Follow the Instructions to get to the View Diagram/View Parts List Page. From here you can View the Breakdown or the Parts List you Require. Hope this Helps. I am here if you Require more Assistance. Let me know what Happens, Please. Thanks.

 Good Luck

 Respectfully
