I have a John Deere 2210 with 680 hours. The parking brake has stopped working. It will not engage when I push on the brake pedal. I can find nothing on line re: how to adjust the parking brake, and the local dealer’s only answer is to bring it in for a costly repair. I think the 2210 and 2305 use the same system for the pedal brake and parking brake. Can anyone tell me how to adjust the parking brake so it will work? A You Tube video or a page from the technical manual (which I do not have) would be very helpful. Thanks!
