Zd1211 blades

[gonnasellit]

Does the Gator G6 blades throw heavy grass clippings out a SD Deck good after you guys have modded the blade holders to accept the RD blades with smaller center hole ?

The clipping discharge in the heavy stuff seems to be as good or slightly better than the original blades. May be my imagination but mower seems to have more power with the mulching blades.

... 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. .

Would 1-1/8 Rear Discharge (or older SD) Blade holder bosses fit these Newer ACS Side Discharge Gearbox Spindles ?

No. The new side discharge decks have blade bosses with a hex shaped hole in them rather than the splined hole of the older decks.

That’s right, now I remember my RD deck having splined blade holders when I replaced blades.

So I did the blade boss mod to run 1 1/8” center blades. Threw on a set of Kubota non acs blades from dealer and within 4 hours of easy flat mowing they were flexing and bent slightly.
Only noticed because I check deck level every spring and my measurements were way off, Took the blade off and looked down them and they were all slightly tweaked in one way or another and not true anymore All 3 of them, no i didn’t hit anything and mow at around 4” height in perfect weed free grass in this instance to try them out.

The blade width is much narrower than the original oem 1211 s/d blade In a vice you can flex them by hand where the originals you cannot.


What 1 1/8 center blades are you guys running because the Kubota non acs ones i have aren’t heavy duty enough
72” side discharge 1211

That’s exactly why I went with the 1/4” thick 3” wide Oregon 396-814 G6 Gator Blades.
Their Strong & more flat than the curved, thin cheesy Kubota OEM blades
