Not trying to educate anyone in the art of egg sucking, but heres some info. I had an old L200 and fitted a nice arb winch bumper to it, got it well and truly bogged at work one day. Super winch to the rescue! errr no. The bumper seems to making nice progress across the wood, leaving the truck behind. When I had it remounted (after the farmer dragged me out and helped me put the bumper in the back) I got the garage to seriously upgrade the mounting points. Check them out, I can still hear the farmer laughing over the sound of the tractor.
