Customer Question

My YTH21K46 makes a high pitched whining noise only when the blade is engaged and mostly when making a right turn. Although is will make noise on the straightaway at times. If I disengage the blade the noise stops. It will not make any noise at all when the blade is disengaged. Perhaps an idler pulley bearing????
