Cut it just like you would a green one except push it very gently, just enough to get it to go over. If you rock it or push it fast the top could break out. Push it gently and in case you didnt hear me, push it gently. Dont cut all the way through it, leave about 2" holding in the middle. And one more thing, push it gently, just enough to get it to lean. And let the saw man get out of the eay before you push it
