We pull trees over when we can. I don't think there is anything unprofessional about it. I just don't like leaving a yard with excessive damage to the turf if I can avoid it. To me, that looks unprofessional. I've only had one bad experience pulling a tree over. It was an American elm, close to 110 feet tall, 5 foot diameter trunk, and infected with Dutch Elm disease, so the city had tagged it for removal. It was located in a side yard with a large vacant lot to drop it in. The only problem was that the tree still had 75% of its' leaves, and the wind was blowing hard from the wrong direction. We used a bucket truck to set a 3/4 inch line high in the tree, and hooked it to the bucket truck out in the vacant lot. The wind kept picking up, and I asked the boss if he really wanted to try this today. Yep. I suggested cutting a traditional notch due to the wind and the amount of pulling he would be doing with the truck. No way, bore cut it. He only allowed us to bore cut trunks over. I didn't feel that it was a good idea, and let him know that, but he's the boss. I bore cut, got out of the way and signalled to start pulling. The wind is blowing hard, the line is stretched to about half of its original diamater, and the tree isn't coming over. The boss guns the truck, gives the tree a big jerk, and the butt breaks free and slides off of the stump. The butt dug into the ground, the boss is backing up like a mad man, and the tree ends up laying down about 45 degrees from the way we wanted it to. No damage to anything, but big time pucker factor watching the butt slide out.
