Just like hooking up rear except for it's UNDER the tractor. It is off set to one side a bit. ( I think right ) so best to crawl under the right side as not as far to reach. Sometimes it goes on lickety split other times...well to me it's like plumbing. ...lots of cursing but I get it eventually!! SO if it comes off and on a lot you may consider keeping your RFM. I am trading 4010 for 2520 and going with RFM. Easy on off and 1/3rd the cost!!
Also better pic of rock shaft hanging down with blade lowered

When I take the deck off my 4110, I tie those brackets up high under the tractor with zip ties, it keeps them up and out of the way, and its easier than removing them.
