Thank you for responding I will definitely check what you mentioned. Its a 2020 peterbilt 567 super tag dump truck. Not sure about the kind of pto but it came equipped from the factory. It has eaton automatic transmission. I bought the truck used with 170k miles .
Hahaha you already know the struggle man but I'm making it work. My mechanic said there could be a setting on the engine which prevents it from working with the brake. For that I would have to find someone with a computer to connect and see if thats the case.
You have to throttle up to use the pto with your foot on the brake.I’ve got a 2020 Pete 567 with auto trans and do asphalt and all types of work with it. Your truck should be in neutral, it won’t work in a drive gear
