To answer the query about the whistle, in the UK it is part of the recommended ppe to be carried in arb and forestry work. As to whether it can be heard over a 660 on full song, I honestly dont know. My eye contact was on the hazards around me, buggered if I want to be making contact with Steves eyes anyway, lol. As far a debating whether or not we used correct procedure, well we probably didnt do everything text-book style, but not every job fits in the the book ways. But we did have a plan workedout with what we had to hand. The tree was firmly lodged in the beech, the tractor available to us was only about 100hp, to tried to pull it out with that, at the only available angle we could get, may have exacerbated the problem. Everything we did, from beginning to end went exactly according to our plan, and the trees ended up exactly where intended. We can go on and on about thist till the cows come home, I'm not saying this is the way for others to do the job, but the way we did the job. I'm always open to constructive criticsm, and am probably my own worst critic at that!! Anyways, lets see some vid of the work of others!! Its always interesting and keeps the forums alive.
