OK, so today I was bush hogging the pasture until the universal broke, and I said to my self, I really need to find some better way of doing this. What I have a problem with is not the grass (the horses keep the grass eat to the ground) it is with the sweet gum, blackberry and like bush and trees that pop up every year. I have 2 4D but it is a bigger pain to spray than to cut. My question, it there a critter out there that eats the broad leaf plants and not the grass as we need all the grass we can grow. Are there any ideas for a new family member out there?
