New Dump truck owner Posted August 13 Share Posted August 13 I have a 2014 Mack GU813 and my pto quit working. when i engage the PTO button my light turns on and the unit begins to beep but when i engage the lever for the dump bed to raise there is no response. no air leaks, no hydraulic leaks simply no response at all. Worked great yesterday and after 2 loads today it suddenly stopped. Any suggestions or debugging tips?
