Found myself thinking about this thread again this morning while on the tractor, mainly all the negativity floating round, especially from those freshly into it or wnating to be.
Getting your foot in the door is something I can't really help with, but ways of making yourself stand out above others and therefore helping to keep you in work I think I can.
I appreciate not everyone will agree with all of these, but these are things that in my opinion make the difference between someone who fells trees and someone who does it well.
Stumps - there's generally no excuse for high stumps (buttresses don't count as an excuse - you've got a saw, use it!). If the side of your saw isn't about on the floor you're doing something wrong.
Snedding - Everyone misses an odd small limb from time to time, but missing lots on the underside isn't good. Likewise, leaving pegs. If you've gone the the effort to cut off a branch, do it properly, especially on hardwood. There seems to be more and more people almost making pruning cuts when snedding hardwood - if your saw isn't up to growling off heavy forks then get a bigger saw!
Stacking - The other two annoy me, but as it's usually me forwarding it out, this is my absolute bugbear. Stacks that look like they've been dropped out of the sky by a chinook are no good for anyone. I'll mention it once, tell you a second time and after that I'll not pick it up until you change your ways
Cutting to length/spec - beleive it or not, stuff gets a spec set for a reason. OK, Chip and firewood aren't always so critical, but still, if your sticks measure 14 ft instead of 12, and the wagon goes out light because it can't fit enough bays on, that's at least two faily important people you've upset so far. More importantly is top diameters/lengths for things like sawlogs - if a load gets rejected because of your mismeasuring, then you'll not be very popular again.
A quick check on diameters is to have a series of marks on the side cover of your saw - the older Jonsereds used to have 5cm, 10cm and 14cm (from memeory) cast into the side of the clutch cover for that very reason.
Brash - tops left hanging and brash 4ft deep a) looks crap, and b) tend to do damage to machines (not talking about purpose built obviously), if you're asked to mash it up a bit on the way - do it. Also, when mashing up brash, try not to leave spikes (ash is probably the worst for this) as they tend to have a habit of finding the sidewalls of tyres a bt too easily.
One thing I've noticed over the years is each and every one of the above tend to surface when people try to go faster than their ability will let them. Get into good habits first and speed will come later.
Overheads wise, a couple of saws, combi can, a few wedges and felling bar and you're away - don't get sucked into needing a 4x4 straight away, surely you can carry a saw and fuel a few hundred metres can't you If it wasn't for having to shift the tractor and trailer about, I'd probably have a little van or maybe something like another subaru legacy again.
You'll likely earn very little to start with, but if you have the right attitude and are prepared to stick with it, then it can be a rewarding job. You'll have good weeks and bad weeks and at times wonder why you bother, but on the whole you should feel great
Worse case, if you don't like it you'v got all the gear you need to go and chuck brash through a chipper
