Yup, me too, I'm allergic to gravity. After 45 years of repeated fall safety training at work, and the fact my dad had a life changing injury from a fall (at age 39) from only 6 feet when I was 12, no one's gotta tell me the safest way to climb is DON'T. He spent the next 26 years of his life in a VA hostpital because of his head injury. I'm not afraid of heights, but that sudden stop at the bottom worries me. I ain't as bouncy as I used to be. If I'm more than 6 feet off the ground these days, I'm wearing fall protection. An ounce of prevention, and all that.
I only use mine indoors, so never bothered getting more than one section. The platform is rarely higher than the bottom notch (or I couldn't stand up under our ceiling). It was a life-saver when I was building my shop (10 foot 'ceiling') and while me and the missus are renovating inside the house. I stood most of my trusses up by myself thanks to that little platform. Sure beats the heck outta going up and down step-ladders and moving them and it is actually a lot safer. I put a small rope across the back side of mine when I'm using it so it reminds me not to step off it, or both sides if I'm out on open floor. Even at a couple feet, a fall at my age may be the end. Ducking under one small rope is a lot better than stepping off backward. Besides that, I can hang tools on the rope too, and keep them close so I don't have to bend over. The older I get, the less bendy I get.
I'm assuming you leave that attached to the tractor for more stability? Setting up scaffolding on uneven ground is not a fun thing to do.
I've got some tree work that needs doing, and would like to do it myself by renting a tow-behind EWP, but every one of the equipment rental places around here have specific prohibitions about using the lifts for tree trimming/removal. Guess too many idiots have dropped trees on the lifts. Looks like I may be stuck paying through the nose to get the tree work done because there's no way I'm climbing up a tree that I'm taking down. There's a reason I'm taking it down, mainly because I don't trust it any more and don't want it to fall on my stuff. I sure as heck don't want it falling with me in it.
