Update to first clearing project over the weekend:
Didn't go as well as planned. I just don't think I have the right tools. I decided to go ahead and venture into the brush (will post photos tomorrow) with a chainsaw and take down trees under about 6-8in in diameter at about 4 feet, then pull out the trunk and roots using chain and tractor. Then I tried to just topple everything else with the FEL, although I have no teeth on it. My JD 4200 seems to struggle pulling the larger ones out, and I ran into one section that had a multiple stump system of five 6inch diameter trees that would not budge, so I had to cut it real low and will have to grind it later. The chain-hook attached to my drawbar even started to bend out after awhile.
Some of the trees were too far gone leaning toward the fence and a couple fell on the fence. I cut them really high, and they weren't all that large, so no major breaks, but one top-rail cracked and popped off. The fact that these trees are so close to the outside of the fence makes me think that the previous owner was an idiot.
The tractor rake I bought was ok, but I bent one tine on a root.
Also wouldn't recommend this undertaking with turf-tires, which is what I inherited on my tractor when I bought the property (came with tractor and gator). Tractor has only 400 hours after one full year of my own use.
The Virginia burn regulations this time of year really cause problems also. You can't burn anything until after 4pm, which means you really only get two hours before it is dark.
The biggest problem I encountered is this:
I would cut down the trees, then pull out the remaining stumps about ten-fifteen feet down the fenceline. This left me with root systems of the biggest trees, tons of tanglefoot and other plants, dead logs, fallen branches, and other debris. It seemed to be too much for the tractor rake, but impossible to pick up with the FEL. Short of hiring some commercial company to come in and tear everything down, I have to completely rethink whether selectively clearing multiple acres of everything but the large trees may be too difficult.
To top off the "perfect day", I decided to go into the pasture and take down an 80 foot, 12 inch diameter non-hardwood tree (I am slowly trying to clear trees inside my pastures as well). Well, even though I notched it and cut a perfect hinge cut on the back, sucker fell the exact opposite direction of what I intended and the very top of it took out one fence top-rail. Great.
Any more suggestions?
