    Here are some pics of our new hammer we just picked up. Should have some frost to bust through with it in a few days. It's a 1300 ft lb NPK unit. I hope it will break some decent rock and concrete. Man the tool is expensive. I priced out an extra one and they range from $750 - $1250 plus frt and taxes. I think we will be charging by the hour and by the inch, especially in the rock. The unit set us back about $25,500 including tax and shipping. We are going to build a bracket for it so we can quick connect it to our new Bobcat A 300 as well.

    Those NPK hammers work good,I had bought a used one a few years back when I started out it was a NPK 4X,the only reason I got rid of it was the place I bought it from said it had a new seal kit in it but it was still losing nitrogen,so they took it back and bought a new MAGNUM RHB 306,it is a 1250 ft/lbs and it works great.
    I too think that that NPK would be too big for that Bobcat.

    I didn't believe that price tag either, Go on ebay search hydraulic hammer. The ones for the mini excavators go for 10k and the big ones like this go for 18+. Big bucks for something so small and doesn't have it's own power source. But boy do they break some concrete and stone!

    THAT should do some damage. There's day's I wish I had something that big. I have a 500 lb'er on my 250, and it is fairly hard on the arms. The fast pulsating on the lines is especially tough on the hyd. couplers. Let us know how it works on the skid if you decide to try it. :salute:

    Was it 25K Canadian? Anyway, it should make you money but they can tear up a machine if used exclusively on one carrier and used a lot.

    Nice unit, best of luck with it

    i think what he means is that the bobcat wont have the hydro flow to properly power the breaker, not necesarily how heavy it is. and the 1250lbs is impact force not weight of the breaker.

    Thats a real nice unit though! have the 310 bust the concrete and use your A300 to clean up the broken pieces. do you have a grapple for it?

    You can save some serious money by getting your bits made up by a forging company.A few years ago,a huge road building co. in our area got theirs built by my next door neighbor--stronger and will last longer than OEM.

    I checked the weight it also weights 1250 LBS and requires 13-32 GPM to make it work. A reg flow A-300 is 20 GPM and a high flow is 37 GPM. So buy the numbers it should work great.

    Those are slick rigs. I ran a power line for my folks two winters ago and we had to get one to bust up 18" of frost. Pretty slick. I wouldn't want to run one for 8 hours straight though.....

    Thanks. Good to know. This is our first hammer so there is a learning curve for us.

    I also looked at the numbers and Bobcat makes a 1000ft lb breaker for the A300. It weighs 1200 lbs and requires high flow. The unit I just bought weighs about 1300 lbs not including the skid bracket that I will need to make. NPK suggests a flow rate of 13 - 32 GPM. My bobcat has 37GPM and my 310 Deere has 42 GPM. We are going to try it on the deere for now and see how it goes. We decided to go with a hammer for the backhoe instead of the skid mainly because we thought the Backhoe would get more use because of the reach. Now if it can work it out on the Bobcat in tight situations,such as in buildings that would be great. A local builder needs to dig some trenches and the frost is 3 - 5 feet thick in some spots. He has a 550 ft lb on his CAT skid steer and it doesn't have enough kick. Because we have so little snow the frost is crazy deep this year.

    Best thing I did last year was buy a 500# hammer for my mini. I can do so much with it. Kept me working all year with misc projects. Now I bail out buddies that don't have them. Works great! Mine isn't as large as yours but it will still do the job, just takes a little more time.

    I really don't think your hammer has enough ass for 5' of frost,maybe the 3' with a little time.You definitely need to establish a face ASAP and work off that face continuosly.That amount of frost after a while gets to you.Certainly not fun,I'd rather be hammering rock any day.I'd use that 892 of yours with a narrow bucket to hump out material.
