I have a 2007 John Deere Z-trak 777. I am looking for a chute that I can raise/lower while I'm mowing to help me around edges that have a few small pebbles so I don't break any windows and would be helpful around flower beds. Does anyone know of a manufacturer out there that might make one that will work on my machine? If so, is there a website I can visit? I appreciate any ideas out there. Thanks!
