I was doing some bush hogging yesterday on my MF150, when I was done for the day I was pulling into my shed so I turned the throttle down to ease into the shed. When I pushed up on the throttle to slow it down the tractor made a loud noise like something letting pressure off and died. The tractor turns over but it will not start. It doesn't quite sound right when it turns over either. Any ideas what happened. It doesn't use oil and it is full. All my fluids look good and my oil pressure guage showed good oil pressure all afternoon. The loud noise worries me.
 
It's really difficult to diagnose a noise you did not get to hear. Not sure if we're dealing with a gas or diesel engine. Fluids are full, so I assume this includes the fuel tank.

Mowing often sends pieces of wet grass or other debris on to the spark plug wires, which can cause a backfire then hard starts. Of course that is out if it is a diesel.
