    I'm gonna wait until he's built and got too familiar with the 135 I see coming, then I'll bring out the English Beer offer.

    Any reason you went with the Biojack over TMK? I like the looks of the moving blade over pulling the tree into a stationary blade with a TMK. Any idea what it's rated for in hardwood? TMK 300 is suppoused to do a 10" hardwood, but I imagine it will struggle with a 10" osage orange.

    Biojack in my opinion is a superior product, yes it costs more, but I can use it as a wood grapple which you can't do with a tmk. Cutting trees is great, but what do you do with them once they're on the ground? I hoe chuck as much if not more than cut with it.

    Second, it grapples before it cuts, making it a much safer shear especially if you're working around houses or power lines, most other shears cut as they are grappling.

    This 300 is rated for 300mm, I just cut a 330mm (13") pine a couple days ago. They rate for a 10" cut in hardwood, and I don't doubt it would do it with ease. For me, definitely worth the extra money!

    So the cutter uses a shear instead of a saw? Does that mean the wood is wasted or used for fire wood?

    Yes this one is a shear.

    This project is for a city, and most of the wood is small and useless.

    We are going to send some samples to a mill shortly to see how much fiber is pulled.

    I got some custom made tracks on today, since you can't buy single bara for mini excavators. In my quick test, these proved to be amazing for climbing hills. Very happy,!

    Those do look very effective!
    And the hill you’re on makes for a convincing argument!
    Where did you get those?

    That's quite a set of toe nails you have there. Do you have enough weight in the machine to make them bite. You have become quite the R&D engineer!

    Yes they seem to grab well, got them from www.interiorundercarriage.ca

    Oh ya it seems to be heavy enough, it was nice climbing a hill with no slipping. Makes for comfortable climbing with no puckering!
