    Default Re: Kena 3pt log grapple

    I'm not worried about the front end being light as I'll have a 1000lbs grapple mounted. My tractor is probably 12,000+ lbs with the FEL/grapple, loaded tires and dual weights on each rear.



    As Gordon pointed out above, I think the issue might be more one of how the reach will be with this log grapple on my tractor and moving about in the woods. Fortunately I'm clearing out a good bit as I go, so I'm have pretty decent room to move around. But I do have slopes in the 20-30 degree range, and I have to come in at angles some times where straight up and down is no possible, so I still need chains on occasion to pull up/down trees from the really steep hill sides.

    Yeah that wont be a issue, I grain drilled pasture this year with a late model 6000 seris deere set up simaler to yours. I was drilling on a hill farm and side hills would give a little pucker factor. Not used to these smaller tractors, most of my seat time has been in full size ag tractors. I never was in danger of rolling over,but you could tell you were sidehilln. LUTT

    Personally I would buy the Wallenstein over this unit. The Wallenstein is a better and thought out design. Just my 2 cents.

    Just saw a pic of your tractor. That's a big machine. I think both the Wallenstein and the grapple in question are too small for your machine.

    Have you considered a skidding plate?

    There's some pics of mine in this thread.

    Log Grapples

    Has anyone dealt with them?
    One of the PDF files in the above quote link shows the grapple fully closed into a neat little package that will grip a pretty small load. The smaller jaw needs to penetrate the larger jaw to do this and I think that's called a "bypass grapple". I don't know if the grapple in the original post for this thread is a bypass grapple or not but it looks like it could be. If you watch that video carefully when closing on the log, both jaws don't close simultaneously. One jaw closes until it hits resistance and then the second jaw closes. There doesn't appear to be a mechanism that makes the jaws move simultaneously. Not a big deal on something like my tree shear, which also has one cylinder controlling two opposing jaws. My question is, if it's a toss up of which jaw closes first, and it happens to be the larger jaw, then the smaller jaw can't bypass the larger jaw in its closed position. Am I missing something?

    That's what I was trying to hint at. But you came right out and said it. I agree 100%

    Check out Addington Equipment. They make some STOUT skidding grapples. That kena looks nice but for me the grapple itself seems a little on the small side as far as the opening. Also the cantilevered pins on the 3pt could be prone to bending. I could definitely see myself building somethin like it though. For the money it might be worth a try. You could probably break it then fix/modify it three times and still be cheaper than most other grapples.

    I did take a look at Addington Equipment. Their website doesn't really have a lot of information. I understand it is more or less a one man operation and there is wait time of a couple of months. Not that would necessarily be an issue. I'll call him up and find out what he would have that would be a good fit for my tractor.

    I agree that the Wallenstein is too small. What intrigued me about the Kena was the category 2 hitch and claim of being a good match for a tractor up to 100hp, which is why I wanted to solicit you guys advice. A range of 25-100hp seem very wide for a single implement.

    So looking at the grapple/rotator specs, would this be a better match? Addington Equipment appears to be using a grapple of similar specs on their 50-100hp 3pt hitch grapple.
