Pruned Cabbage Palms today at one of my accounts. I do this once a year right after they produce their flower stalks. I did 15 and have 7 more to do.
This is called a "hurricane cut" - one that only leaves the newest shoot plus one or two more fronds.
I use two different size extension ladders plus a Milwaukee M18 cordless Hackzall with a 12" carbide pruning blade and a Kebtek cordless pruner.
