NO Drilling or Modification needed to install this chute blocker. This is designed specifically for 61" Ferris ICD Deck.
Our Swivel (open / close) Chute Blocker Plate fits all 61" ICD Deck by Ferris or Snapper PRO with the slope front deck design, this will NOT fit deck with flat front. The installation is really easy. Simply unbolt the factory chute by undoing just a few bolts and attach our chute blocker plate with the provided nylon locking hardware and you're done! Please note that you should NOT tighten the nuts all the way tight because the nylon locking nuts will ensure they stay in place, you need the nut to be loose because that's how the chute blocker can open and close without interference.
Now you have mulch machine! or rather, you have a zero turn mower than won't throw rocks or any hazard randomly at your house / car / window / etc. This is essential when you're working on long overdue / heavily grassed / weeded areas.
