Don't know but this may be more of an East coast question. Most all of the trees over 24" that I cut are oaks, followed by maples, and a few beeches and poplars. Only rarely do I cut other species of that size. Yesterday was one of those rarities. LO asked me to cut a 28" locust. Heretofore my experience with locust has been spindly weed trees 15" and under and splitting for fence posts as a teenager. This tree was more like an oak - it had a nice straight truck and a large bushy canopy. It was located on a small bank at the intersection of a county lane and a county road and was weighed over the lane. I treated it like I would an oak and tried to fall it against the weight into a field but with four rows of wedges maxed out and a rope not high enough in the tree, it required hinge thinning beyond my comfort zone to start the fall. You guessed it - the hinge broke almost immediately in the fall, the rope tension pulled the trunk forward which caused the stem to plunge straight into the ground about three feet from the stump whereupon the tree spun and fell almost 90* from the intended. Four hours later my cutting partner and I had the canopy out of the lane - not talking firewood here - lengths as big as my 4wd truck would pull. The downed telephone pole blocking the road only took about 5 minutes - thank GOD no was passing by at the time. Real YouTube stuff. Long intro to, the landowner has some large doggy walnuts to cut as well as some sycamores. Clearly, I was not experienced enough with the characteristics of locust. I have zero experience with large walnuts and very little with sycamores - other than parking my saw any advice on what I should look out for with these species?

Oh no...
Well, my only suggestion, if you plan on continuing these escapades.
Get your self a Big Shot, some throw line and a couple throw bags. Makes it effortless to put a line 90' up a tree.
Follow that with some good arborist rigging line, (I like the 9/16 samson stable braid) add at least one snatch block for redirection and you can move the world.
Worst case scenerio it will keep the trees out of any high value targets.
As for locust, the only one I was ever involved in, I managed to talk our way out of doing, as it had all sorts of height and bad lean, with no where to go. At the time we neither one of us had insurance or anything.
