I would not attempt to do any tree removals for landscaping customers without tree insurance. Just my one centDon't worry about it.
I have a copy of TCC and others books.
My gear is coming and as it arrives I'll be able to practice.
Fortunately I have some experience with chainsaws and other equipments as I
have my own landscape maintenance business.
Don't punish yourself with cheap pads on your spurs. Even when you get them adjusted right they will kill your legs after a couple hours. I got climb right aluminum pads with the velcro straps for a little more than 100 and they made an 8 hour day feel better than 30 minutes on the old pads.
