Nothing but rock. The claw/hook is tearing it up. Bulldozer just humming along.

He definitely needs to work on reangling the ripper shank once it’s in the ground. That’s why he’s not able to rip better and more effectively. Once it gets into the ground, you have to angle the upper ripper hydraulics out so the tooth on the shank gets a better angle and can apply more of the force on the tip of the shank rather than on the entire body of it. The way he’s doing it is damaging the entire ripper shank and it’ll eventually break it off.

Los que verdaderamente amamos los tractores gozamos al escuchar el motor,las orugas,el sonido del acero contra la dura roca.Y no alguna tonta música que ponen en los reels.

Komatsu made a big splash when this was introduced several years ago. Then it just died, this is the first I have seen of it since. CAT even had a helicopter fly around and take pictures of it. CAT still owns the large dozer market with their D10 and D11. Rumor is they have a D12 designed on computer but have not built any or disclosed any to the public.

Look,to all of you that bash Cat. Cat could build anything they want. Just watch a D11 working along side a 475 or 575. There is no comparison. Cat is #1 in heavy equipment for a reason. To build the biggest doesn’t mean the best.

I think the 575 is like 80,000 pounds heavier than a D11. And just the fact they quit making them says a lot. I’ve been an operator for 40 years and have run both Komatsu and Cat they both make good machines. But in my opinion the mining machines I’d give the nod to Cat.

Believe me I’m not a “It’s gotta be Cat and only Cat” type guy. But run a Cat on a 12-14 hr shift,then do it in a Komatsu the next day. On the 3rd day you choose which one you want to run.I bet I know what most would choose.
