Hotburn76, I dont have a lot of experance with Horton's I have helped a few of the guys with theirs so I am not sure if this works on them it depends on clearance. You might try using a crank down like they tie down loads on a trailer or tie an ATV down on a trailer. we put a steel rod across the slot for the wheels and crank it down enough to loosen the string to work on it. Be carful not to put any pressure on the excetric wheels. Lee
