When we cleared off 30 acres of new property (it was old grape fields that were overgrown) we used a JD 450G. Cleared all the fields which contained brush, trees, grape roots, post, wire and some topsoil all at once. We pushed everything into large piles and set them ablaze after they had a couple days for the weeds to start drying out. As you can imagine, 30 acres makes a lot of big piles. We burned about half of them and let the other half stay for now (makes nice hiding places for rabbits and birds). We do not need permits here and are allowed to use tires to start a brush pile on fire (only 2 per pile). The fires would burn for days as the post would burn down under the topsoil that was in the pile as well. Once the piles burned down enough we dug out a hole with the dozer and buried some of them. After a year the other piles the TN moved into the brush and others got piled into larger piles since it was mostly top soil left as most of the wire was destroyed after the fire weakened it so much that it just rusted away in a years time. Now it has been 4 years since we cleared the fields and the piles we left are what we are pulling topsoil out of now. It is some of the nicest top soil around and it is FREE /forums/images/graemlins/smile.gif
Now for the reason I started this long tale, when we were burning we used the dozer to control the fires. We would not drive up onto the fire but use the blade to push the pile into itself as it started burning down. The 450 had a 10' blade on it so it could push a nice pile. The biggest worry we had was the hoses if the fire was too hot as there were a lot of hydraulic lines for the blade but we were lucky and did not have any problems with them. So good luck and make sure you clear away any dead grass that might want to start up before you start your fire. Our fields were barren dirt when we burned so we didn't have to worry about them catching on fire but if we were to burn any piles now (there are a couple left) we would plow up the ground around the piles first and till it down to give the field a buffer from the fire so we don't have a bigger fire then we wanted /forums/images/graemlins/blush.gif
Well, have fun and keep your truck away from that fire /forums/images/graemlins/wink.gif
