Hi, I'm trying to find out how/where to adjust my parking brake on my 2013 LTX1046 hydrostatic lawn tractor. I usually empty my bags of grass while leaving the engine running using the parking brake/cruise lever. For some reason, the parking brake doesn't want to engage when I have the brake pedal depressed all the way. I don't know what, where and how to make an adjustment to remedy the problem. If anyone can point me in the right direction of doing so, I would sincerely appreciate it. Thanks, Ray
