I bought today a zero turn rider model 247.28933 . i drove 4 hrs to get it . the lawn mower make 2 noises 1 is the motor. the second is i dont know to me it sounds like gears are grinding. the second noise is louder than the motor. When i called to ask question i just got passed from one person to another. i got no answers. is this normal. when i call a different store they wouldnt answer my question. when i tried to set up a apptment. they tell me it well cost me if their is nothing wrong. i dont know if their something wrong i just know that ive never heard a lawmower that is this loud and with 2 complete noises. when i asked about returning it i still cant get a straight answer. WHAT CAN I DO
