I have an '04 sears craftsman 18hp garden tractor and whenever I engage the cutting blades I get a squeeling sound at the mower deck? Does anyone know what causes this and what can be done to correct this problem? I did check the belt and also put on a belt lubricant.

Thanks
Fritz

Don't know what you mean by belt lubricant... ick. Anyway, have you ever greased the deck spindles ? It could be the grease is gone and your bearings are failing. Check underside for grease fittings on each blade spindle.
