I am new to the forum and totally amazing at the content! I am interested in using the new blades (#795292 - flat blade w/ lengthend cutting edge) with my 60" Hustler Z. The problem is that it is about 4 years old and has blade saddles and 1/2" mounting bolt. The new blades are for the saddle-less design with 5/8" mounting bolt. I do like the idea of the new decks not "locking" the blades into place with the saddles allowing the blades to give if something was hit. It seems that the new blades should perform better as well. Can I retro-fit my Hustler Z to a saddle-less design?
