I bought a used Kubota F2690 lawn mower with rear discharge a couple of months ago. I read with interest about some of the comments about the mess it leaves under the mower. Mine does have some which I will be cleaning in the spring before I use it. I thought that some kind of cover could be attached underneath to minimize the problem. I even looked at my grand kid's sleds and wondered if I could fasten them. I'm thinking that a number of materials could be used including plastic, fiberglass, etc. Has anyone ever done that and if so, how has it worked? Thanks.
