I have this idea for a winter project to take a 52" Toro walkbehind and drill a 2 1/2 in hole in the deck with a holesaw. My idea is to drill the hole directly over the center blade where the sharpend part of the blade would connect with the wood. Does anyone have a source to get a flange to mount in the deck so a metal pipe can be screwed in to use as a chipper when needed and a cap can be in place the rest of the time. I just want something to chip up the dead fall so I don't have to take it away. This should work with double blades since the blade that cuts the wood is in the spindle cradle. Comments please.
