So I was just out cutting a big swath of the farm trees which have been overrun by vines. Some are grape, we have thousands of those(make great jelly)and most are climbing poison oak and ivy. Does anyone have anything they have tried, not to toxic...it is farmland. We grow rye and other types of hay, clover and veggies. I just cut about 30 trees from 3 inch to an ash well over 30 inches at the base. Just about every time I cut the tree, the vines pull other trees on top of me. Thanks to my head gear and chaps I'm still able to get things done. I'm just frustrated with the vines. Now I am off to fix the Kubota tractor, blew the air chuck off the front tire. Pushinn stuff around. Time to start burning the brush too.
