Using my Kubota L3301 HST Diesel Tractor to Push Black Willow Over and Pull it out of Lake

Using my Kubota L3301 HST Diesel Tractor to Push Black Willow Over and Pull it out of Lake. This used to be a 5 trunked Black Willow tree, that has slowly been dying. Two of the trunks had already fallen. Two were pretty much dead, and the last one was not healthy. Two of the trunks were leaning and easy to fell. The last one leaned several ways at once, and my attempt to make a cut to fell it, left it standing. So I simply used my tractor to encourage it to fall.
