I installed a snowblower on my x758 but I forgot to latch the draft arm rod to the latch plate (item 25 in the image below). So now the pto shaft rubs on the draft arm rod. For some reason I can't lift the draft arm rod high enough to sit in the cradle of the latch plate. Any idea what I'm doing wrong? Should the draft arm rod move freely or do I need to adjust the range/limit somehow so that the draft arm rod will go higher? thanks
