I own a used John Deere X530 with a 54" mower deck. I notice that if I try to engage the mower deck after just having started the JD, it will cause the engine to cut off. If I allow the engine to warm up a couple of minutes, then it will slow the engine until it fully engages the PTO, then come back up to RPM. Does anyone else experience this problem? Do I just need to allow the engine to warm up a bit first? Or is there something else that I need to look into? In advance, thank you for your help.
