I dropped a pretty big elm in my front yard. About 24" at the stump. I cut the trunk in three sections each about 6 feet long. Then I put a chain around them one at a time and used my 420 to drag them to where I was going to cut them up. I looked up the estimated weight on a website. They average about 800 pounds a piece. The 420 had no problem with them going up hill. Needless to say I was pleased.
