Riding Lawn Mowers

I have a 2010 GTH26V48LS with less than 30 hours that just started making a rattling sound from the brake/clutch linkage area. After searching this site, I see this possibly a known issue for certain models and maybe related to the drive belt or links. Can you tell me if my GT is one of the affected models and what the fix is for this. My nearest dealer is over 150 miles away, so I would like to be able to order the parts and make the repairs myself. Thanks in advance for your response.
