good decision!:thumbsup:
You will be amazed at how much grubby backbreaking work you can get done in just a few minutes with the DK plus grapple combo. Once I was properly set up as you will soon be, I could get more done in half an hour than I could working all day without a tractor or in a couple of hours working with my trusty CK20 plus grapple.
If you are planning to take out trees I'd suggest you practice with various techniques but in general the following works very well with a DK:
Raise grapple to above your eye line and push on the tree while in 4wd low range. This will generally put enough force on a tree less than 5-6 inches diameter that it will expose some of the lateral roots. Next back off and do the same from 90 degrees if accessible. Then lower grapple and insert it under the exposed root ball if you can or at least under some of the exposed lateral roots. Drive forward and curl/lift at the same time. If that doesn't immediately pop the tree loose (for bigger ones it won't) then work it a bit with the same technique and then go back to pushing on the trunk about 8-10ft off the ground. Once you get it to tip/unroot just stick the grapple back under the root ball and drive forward to free it up.
I rarely use the chain saw for dropping a tree. Leaves too much of a hassle getting the stump out. For trees bigger than 6 inches or so it is best to use a ripper/BH combo to tear up the lateral root system before pushing the tree over and using the grapple just to carry it away.
Good luck with the grapple
