The lower trim piece lifts right out, it just sits over a couple of pins, but it turns out that the next obstacle is the loader arms. I was just at the dealer this afternoon and asked what I needed to know to safely lift the loader arms straight up, and then work under them, since I had seen the mechanic do that to access the oil separator etc. Answer: just lift straight up and then engage the lock lever and turn engine off. Bucket position doesn't matter he said ( probably best to sweep manure out of bucket first). I sort of think it still is dangerous without a proper backup support for the bucket and it seems like I have seen some threads on the forum about building some. If all you're going to do is reach under and pull the screen out should be ok.
