Small Engines (Lawn Mowers, etc.): 2 out of 3 blades not turning, mower deck, horse rider

Question
John, I have a Murray 19 horse rider and I was rolling along when the deck vibrated hard and I thought something flew out from underneath but, I didn't see anything. I stopped mowing and checked the belt, but it looked fine. I started back up but the left and center blades stopped turning, so I was left with a 14 inch cut on the right side. What is my problem? Thanks, Ronnie H.

Answer
 Hello Ronnie:

 Remove the Deck and Inspect it Carefully. I have Never Seen a Mower deck Cut on the Side like you are Describing. I have Seen then Cut in the Middle and the Two Outside Blades Not Cut. Send me the Model Nimber of the Mower, Please. Not the Engine. I can then Look Up the Mower in my Manuals and See what Style Mower and Deck we are Talking about. Hope this Helps.

 Good Luck

 Respectfully

 John
