I agree about being able to push down sizeable trees. If you use good leverage by placing the front edge of the FEL bucket up high on the tree, you can take down a good sized tree. Obviously, you need to make sure that by raising the bucket a lot when you are not on level ground, you are not raising the center of gravity enough to create a dangerous tip-over situation. You can make the task easier by grubbing around the bottom of the tree. Obviously, if you remove some dirt on the side of the tree opposite from the side you are pushing on, that dirt doesn't provide resistance to the tip-over in that direction. And you can obviously make the task easier by grubbing out the roots on the side you are pushing on. I have done it many times. At first, I made the mistake of pushing sometimes with the front edge of the FEL bucket lowered. I bent the bucket down a little bit in the middle doing that. After that learning, I push the tree with the bottom of the bucket level so that the stress on the bucket is distributed widely and not concentrated.
