Thinings value

[muldonach]

Spot on, not a commercial wood.

 

Although it is very clear that this is not a commercial wood the point remains that trying to remove a random selection of trees from a planted matrix will be both expensive and difficult. Talk of winching tushes of 20 poles through such a matrix is naieve - and thats after you get them on to the deck in the first place.

 

In our conifer woods whch were all originally FC planting there are regular missed rows (racks) which were missed so as to provide future access - are there no missed racks in the wood in question?

 

Assuming there is not then there is still a middle ground which will accommodate some of your clients wishes and greatly aid with getting timber to roadside - bend the extraction racks, get then cleared and then herringbone into them. You will need a skidder or forwarder - but you need that anyway

I'm glad someone else knows what ' tushes ' mean, it's a word that is rarely used these days, since mechanised harvesting took over. Tushing out with the county a thing of the past!!

I know it'll be difficult and expensive for the customer but that's the way they want it done. I have given them the options and they want it done the way they've asked.

The site is around a house plot so any equipment has to come up the driveway.

I don't have a harvester or forwarder in the shed so have to use the kit I have. I cannot put a vehicle into the wood so any plan that involves that is out.

I'm not as green to not realise the trees will be tricky to extract.

The damaging the remaining stems concerns me though.

We knew the term and would call the bunch of logs a tush but tended to say skidded out.

 

Long gone the days for me when I came blaring out of the woods with 8 half tonne larch trees, tip first behind the County, still got the machine though. In fact it was very versatile from second thinnings to big hardwoods but by 1984 I had succumbed to shortwood for softwood and fitted a grapple loader on the roof.

The damaging the remaining stems concerns me though.

 

Actually if you run the winch tractor perpendicular to the line of extraction you can steer the stems by moving back and forth.

 

I found 4 chokers per drum was about optimum, even though I would double choker two stems to one chain frequently (I tried rope chokers but the igland 4 tonne double drums snapped them too easily).

 

Back in the day when I did first thinnings the trees were about 20 years old, seldom bigger than 6" diameter or 12m long, so the only damage was turning out of the rack and that tree would be felled last.

 

Then the trees were at 5ft spacings and to make any money we had to cut a large selection of PSR and rustic poles, losing money on anything sent to pulp.

 

The larger trees which were not wolves were less good for PSR and because of the price size curve being what it was also not big enough to produce bars, so there was no real advantage in felling them, they would be more valuable in later thinnings or final crop.

 

Being idealistic then I reasoned that a geometric 1 line in 4 thinning would lose 25% of these trees with higher potential, so I would produce my rack at right angles to the planted lines, with the Holder and tongs I could skid stuff out without damaging the remaining trees as I cut and selected and formed my rack to avoid the better trees.

 

Elsewhere the FC had largely caved in and were taking 2 lines out of 6 to allow volvo 868 forwarders to work as their target was for volumes of industrial wood rather than concentrating increment on premium stems.

 

My efforts all came to nought as the plantations were bought by RSPB some years later and clearfelled to revert them to heathland.

 

I realise if you are on a steep lope there is little option but to go straight up and down..

Just hack trees down randomly, drag them out, when the customer gives the big thumbs up, call the Timber lorry and be happy with what they give you.

Sounds like a perfect job for a wee digger and grab

You say they ( the owner/customer ) want it to look like a natural wood but that is never going to happen if its a soft wood matrix . It will never look like a broad leaf random natural wood . Just a thought .

Call in JJ Baldwin!

Brilliant !!

[TimberCutterDartmoor]

I KNOW!!!

 

Since the customer's got money to burn, why don't you get a freakin' great tower crane in and crane every single tree out straight! Up through the canopy!

 

Deliver it to your working area and process!

 

Absolutely fantastic!

 

You'll need to put the civils in place first and maybe crane the tower crane in with another crane but it will be less grief than the landowner wants for himself.

Heli-Log it all out!!!
