Just like a lineman, gaffs n lanyard.
The city's palm contract entails some 4.5K street trees, and the company I've subbed for the longest, had that contract for two decades.
My longtime friend Brian did them with a bucket, averaging 45 trees a day.
Taking over for him when he took vacations was not something I enjoyed, I hate buckets!
The hairy ones are up there 80-90 feet, way over a 50 bucket, and you can see the old gaff trails goin up the high side!
Lots of veterans say fug that. My trick was tyin the trunk to the bucket fully extended to add a bit more stability! Kinduva big no no, but it made me feel better gaffin up to a head forty feet further up!
The only wash fans I've seen fail were planted on bedrock with a thin layer of topsoil that went over roots n all.
There's a reason palms are one of the few trees left standing after hurricanes. They are amazingly tough.
