Went to a dealer today & drooled all over a ZD1511 72" Rear Discharge unit
Man I like it but just ain't sure on tier4 DPF BS.

Then get the 1211. Ours should be in at the end of the week supposedly.

$4 Grand MORE for 6 extra hp.
Us farmers & shade tree guys are clueless when tier4 electronics starts acting up.

The 1211 is the same mower but with 24.8 hp and no tier 4. You can get a 72" rear discharge. That's why we're getting it is to keep from having emissions on a lawn mower. Biggest difference is a real nice suspension seat vs the air ride on the 1511

I just couldn't make myself pull the trigger today on the ZD1511 "Tier4 LawnMower".

I always buy the bigger engine on EVERYTHING I buy, BUT the Tier4 is pushing me towards the ZD1211 24hp.

The ZD1211-72 frt & rear axle widths looks the same as the ZD1511-72 as far as I could tell ?

Both has 61.4" wheelbase.

I couldn't find much difference between the two besides air ride seat, more hp but chocked down by emission stuff. I don't think adjusting the governor to 3200 would hurt anything if your low on power but the one I ran wasn't lacking at all. They are awesome and will mow full out if the ground will allow it

I turned the blades to 3&9 o clock & visually looked at them from frt of deck, today in the showroom.

I'd estimate 3/4-7/8" blade overlap. Not near as much as I'd like to see :-(

When tips of blades get worn off from grit & pebbles at 18k rpm, you have VERY LITTLE blade overlap.

IDK why mower mfg's don't have 1.5+" blade overlap like Bush Hog RFM do.

They could move center shaft housing out more & use longer blades.

Didn't you notice how thick those blades were? What did you think about that?

I'd "guess" the blades were 1/4" thick idk.

I did notice the rear discharge blades didn't have as big of air lift wings like the side discharge blades.

The rear discharge deck also has a narrowed discharge opening so the opening isn't 72" wide and the grass gets double cut on the Rear discharge the way it's designed ...

The ZD1#11 72" rear discharge deck is open all the way across the back with Three Separate Rubber Deflector flaps partially hanging down to keep exhausted clippings off engine & transmission.

I really like the way it's designed, as I've been mowing with rear discharge since 2001.
