Looking for suggestions on how to turn square bales into chopped straw. So far I've tried using loppers and shears inside a garbage can, without much luck. Both those tools are kinda dull however....the straw just twists sideways between the blades. I'm not opposed to buying new tools, or sharpening these ones, but don't want to spend any $$ on them if they aren't the tools I need for the job anyhow. I thought about using a weedwacker.....anyone tried this?
