I had a friend help me on a recent tree job. I was ~50 feet above the ground in a large multi spoked maple. The spoke I had to remove was split near the base and overhanging the roof and power line to the house. The job was going very slowely (intentional) so I brought my friend along to help me reduce the climb up climb down climb up climb down scenario of working alone,.....Anyhow....at one stage I had him tie one of my saws on a line so I could pull it up to where I was....He tied a pretty good knot....it held until the saw was about 10 feet from my grasp and then came untied.
My saw went straight down and struck a stump, bounced up in the air and then stuck bar first into the turf......broken handle bar, broken spark plug, broken cover bent cylinder head cooling fins, broken trigger. I ordered the parts and drilled some holes in the broken handlebar, pieced it togtehr with wire, replaced the spark pug, carefully straightened the coolinf ins and bzzzzzt ran perfect.....finished the job and now the replacement parts are in so time to break it down and make it whole again.
so boys and girls...check yer knots!
