I have a Maple in my yard that was knocked over by the wind. The trunk at the widest is probably 5 foot across. the tree is bent. There are 2 truncks which are arch shaped and putting pressure on eachother. I bucked up the smaller logs. But the 2 larger remaining trunks are under tremndous pressure. I was able to cut a section maybe 5 foot long at the end of the trunk (towards the top). The end popped like a "Barbers Chair" I think thats what the call it. Well the rest is under maybe more pressure and when I try I am pinching my saw blade. Any tactics or advise ?? I tried to put any under cut so when I bring the blade top down it may relieve pressure but it is really so tight that the blade keeps getting pinched! Thanks for looking and any experience and advise would be appreciated.
