Does any one have any info on a Kemp Chipper shredder? I see that one is for sale, used locally that is powered by a Gravley two wheeled tractor. I cannot find any info on these shredders. Are they made by another company or did they go out of bussiness? Thanks for any info. If I can get this shredder I can handle all of the light debris generated landscaping saving on some dumping fees in the process. Thanks for any info.
