tow-behind garden 'sled'
I would like to make a simple sled to tow behind my lawn tractor. I have a little trailer but I find it much easier to rake or hoe dirt, etc. directly onto a ground level semi flat/curved surface. My neighbor had a long (8' or 10') sled of fiberglass with slightly curved sides and wooden stiffeners underneath.
I'd thought of getting a thick panel of vinyl or some thing and attaching a towrope but how do I keep the front from digging into the lawn/dirt?
