Zd1211 blades

Well thank you for asking, I’ll be on the lookout to see if anything pops up

My ZD1011 has a 15/16 hole in the blade. I could find a Gator blade that was correct in every dimension except the center hole so I bought a set with the smaller hole and a 15/16 diamond hole saw and drilled the bigger hole with the drill press. It took some testing and a good bit of cutting fluid but, it worked. The Gator blades are HARD steel and the newest version has carbide on the bottom of the blade.

First post here so be gentle! I just modified my ZD1211-72 to use the old style blades with the 1-1/8 hole. I ordered an extra set of K5955-34380 Spindle Boss (three each) at a cost of $45 for the set. I then machined the ends of the bosses down to 1-1/8 to fit the blades with the smaller holes. It's a simple mod that any machine shop can do in a few minutes. You can change back to the new 1-5/16 hole blades by simply installing the original blade bosses. I am installing Oregon Gator G6 mulching blades part no 396-814. I'll post my results with the cut quality shortly. I'll also put pictures of the mod in my album as soon as time permits.

I just cut about an acre with the Oregon blades and I am pleased with the outcome. Mostly leaves, weeds and some centipede. They cut and mulch leaves as well as my ZD326 Pro deck which was built prior to the "improved" ACS deck with the 1-5/16 spindles installed on the ZD1211. End result is better quality cut and longevity compared to OEM at about a 25% cost savings.

Did you get any pictures of new and old blade bosses. Just trying to understand what you did. Thanks. Have same mower and need rid of factory blades

I have pictures but have to first transfer from my phone to computer. Mod essentially consists of reducing the diameter of the end of the boss which protrudes through the 2 washers into the blade from 1-5/16 down to 1-1/8. The small end of the boss is machined down to 1.120" for a distance of .205" from the end. The rest of the boss is left at 1-5/16 in order to still fit the original washers. I should be able to post the pictures later this afternoon.

Ok thanks. If not message me I’ll give you my email or cell to send them to me

Hopefully I'll get this right.
The ideal depth of cut is .206 instead of the .200 shown in the pic. The diameter of the turned down section should be about 1.120".

Thank you, I will look into this. Bet if you had a bunch of these made up, everyone with an acs deck would buy them.
