I have a MTD Lawn Flite rider. The seat as been replaced along with the Id number. The engine is a 11hp with a 38" cut and a five speed trans. This is a real work in progress I could really use your info concerning this rider. This rider runs well and cuts well, I broke the drive belt and need to replace it. I,ve tried 84" seems to be too long, 83",83.5" too short can anyone help.
