Adjusting the parking brake on a New Holland Genesis tractor 8670, 8770, 8870, 8970

This is a hands-on, under-the-tractor walkthrough of adjusting the parking brake cable on a New Holland Genesis 8670/8770/8870/8970, filmed by an actual owner working on their own machine. It shows the cable location behind the tire, the jam nut adjustment with a 7/8" and 17mm wrench, and discusses when adjustment runs out and a $1,300 parking brake disc replacement becomes necessary. Useful for owners doing their own maintenance rather than shoppers evaluating the tractor.

An owner-operator sharing a real maintenance task performed on their own tractor, not a dealer or promotional video.
