If you put a tachometer on the engine and check the rpms (not a bad idea anyway to make sure it is running at the 3600 rpm setting) unloaded and then after you engage the blades, you should see the engine have a short drop off in rpm's and then it should gain back the rpms back to within 50 rpms of original reading, if the governor is set properly.

With the bagger going, I'm not sure if the governor will be able to compensate for that much extra rotational mass being turned.
Thanks, I thought he was blowing smoke. I had never heard that claim before and I have heard some good ones over the years!
