It's an 8x8 mini forwarder...

That is pretty slick and i bet pricy too.
Notice the rutting. They'd have to shut it down and wait for the soil to dry out here. Bad, bad forwarder.
.I think that you'll find that the fowarder traveled the same route many times with the same demo logs , I seen a few more of there video's and did not notice it tearing up the woods that bad but they may have chosen better conditions .
What machines have you found that make least mess/rutting in your area ?

ground based extraction means disturbance. Visible or not, more than 3 passes with any ground based machine will creat permanent compaction affecting site potential, wet or dry. So, depth of rut does not matter as long as the rutting is mitigated through proper closeout, and the % of the site with significant disturbance is kept to a minimum (hopefully under 6% of total acreage, including landings.) In woods infrastructure can be used for all later harvests, assuming the next harvest uses the same or similar technology, which as slowP will attest to, may or may not be the case.
Forwarders will outperfrom skidder productivity where extraction distances are greater than (depends on particular equipment here) 1/2 mile.
BTW, skidders have a lower psi than human foot....... but thats not exactly measured loaded with a big ol' drag.
My uncle had a massey fergusson tractor like those but bigger it had a full role cage. It was was used for skidding small jobs out.see if this will work .http://www.payeur.com/produits/usages/P1030562.JPG . The pic wouldn,t paste up so here is a link .. What are these . I see them hooked up to the forwarder trailers and plumbed into the tractors hydraulics .. Pretty slick looking ...!!!. I still like the Forcat best .......Other than price , it doesn,t get any argument from me ..... These rubber tired jobs could be driven down the road tho ...
I spent a Saturday at a seminar. Weyerhauser had some presentations on soil compaction. Strangely enough, their studies found that the trees planted in skid trails only had growth affected for one year. Then the tree roots grew beyond the compacted area and growth was comparable to the trees planted off skid trails. Maybe different soils than other places though.
We're supposed to require subsoiling on all skid trails. My concern is that in a thinning, the subsoiler, which is often a shovel, pops the roots of the leave trees. I talked to the professor who did the Weyco presentation and he thought the subsoiling was way out of date as fare as a BMP.
The concern here, with operating in mud, is that sediment will get in the creeks. So, if the tracks are rutting for 10 feet and are 6" deep or more, it is time to shut the machine down and go home.
That really puts a limit on the days when one can skid. July, August and September, probably with a few days in July and September being too wet. Add this restriction to any fire season restrictions, and you can see a timing problem.
We are lucky to have Pumice soils which drain and dry out quickly.
