Them bloody harvesters really hit a nerve with me, I lost a position as well to one of those and swore I wouldn't again and opened my own business. The smaller wood lot owners don't want one of them things chewing through their woods but they still want to sell the timber...not everyone is in a position to open up a business I realize, so target the harvesters week points, no good on slopes and they can only handle trees up to a certain size, it's a hard industry to keep a job in so I realize cutting jobs are hard to come by, but invest the time to look up smaller companies etc and see if you can find a spot, persist long enough and some thing will come up. Other wise, I dont want to but have to agree with the above, it's a ever changing world, maybe bite the bullet and learn to operate the very thing that put you out.
Best of luck and really hope something happens for ya!!
