So I finally got all the bugs out (for now) and my old girl is ready to work, going to hook up the finish mower and take her down to my property. Is the top link what I use to set the level front to back? And as far as using the hydraulics, if I understand correctly I need to engage the PTO in order to do so? That seems a little scary, if I lift the deck the blades will be spinning? Sorry for all the dumb questions, never had anything like this, I'm a city boy!
