Large, dead ash clearance job. Advice appreciated in Forestry and Woodland management Posted September 30 · Report reply Sounds interesting J. I've often wondered about a similar set up for 1st thinnings in spruce, but never got as far as actually costing anything. A couple of thoughts...… When you load the whole tree onto the forwarding trailer, with them being largely dead, brittle ash you're likely to break a lot of the branches off. Some of these will get left behind in the wood, mostly the smaller ones, but hopefully you'll retain many in the bunk. This might actually increase the capacity per load if I'm not mistaken? The same at the point of chipping, hopefully it will be more compact, resulting in more material per grab getting fed into the chipper. Jenkys are extracting brash from the mats along the road for us and chipping into walking floors in the wood, so there must be some sort of money in it. Clearfell, after everything has been extracted the forwarder lifts all the mats, stacks brash at roadside, tracked chipper comes in, loaded by excavator with grab straight into a walking floor. Commercial operation, non-grant aided as far as I know, customer getting a return on the brash. On a slight downside, if the spacing is that tight then a 30' pole is going to be quite something to manoeuvre around! Either you're going to skin the retained trees which isn't going to be good or you're going to break the poles, especially as they're brittle ash. Realistically I'd think you'd probably do both which is the worst combination. There are good reasons for short-wood working in thinnings as opposed to long-wood. Be interested to see how you get on with it and if the figures add up.
