When I was running a 3 pt. hitch snow blower on my 2005 M6800, a very noticeble rattling/knocking sound started coming from the tractor. I at first thought something like a valve broke in the engine. I disengaged the pto and brought the engine back up to speed and no noise. I went back to snow blowing (just clean up, not much of a load) and the noise returned. I disconnected the snow blower from the pto, engaged the pto with no load and brought it back to 540 rpm with tractor not moving and no rattle. Also, the pto does not spin freely when disengaged, should it? Anyone have any clue what I should be looking for or what is going on?
