    Does anybody use an OCDC on their 7 Iron II deck for mulching leaves?

    If so, what blade setup are you using?

    I run an Exmark with the chute blocked for making rough leaf mulching passes. But, I learned that my standard lift, notched air foil blades create too much blowout. Also, my hi-lift Gators have more blowout than I would like. The best blade is a regular Gator. No, the result does not leave the debris evenly spread, but that can be solved with a wheeled blower, or with a cross pass with the mower, chute blocker removed.

    I have a JD 717A, and tried a chute blocker. The only blades I have are the OEM blades. They do a great job on turf, but create far, far too much blowout for a simple chute blocker scheme.

    Which leads me to my question: What blades are the best choice for rough leaf mulching, with a simple chute blocker scheme?

    I ended up using my 717A very little over the leaf season because I couldn't mulch leaves with it. I still had properties for discharge mowing, so I did not want to mount a mulch kit. An answer in another thread revealed that to mount/dismount the mulch kit is a large job. Therefore, an on/off procedure is out of the question.

    I posted this in another thread a few weeks ago and received no responses. Perhaps nobody is using a simple chute blocker setup on the 7 Iron II deck.

    go to home depot and get some alum. trim and use duct tape to attatch it to the front of your deck to make a anti blow out baffle. When the leaf season is over rip it off and your done. The concept is simple . let it hang under the deck in a "L" shape just a little to help direct the air flow from blowing the leaves out . its not pretty but it works and the cost is minimal. hit the search for anti blowout baffles and ther should be much info on this topic

    i have the same mower and have the full mulch kit.friend has this mower with just the cover plate.he called and wanted to play so i loaded up and went over.this nutt had put leafs all in his yard.he has stock blades and i dont know what mine are they came with the kit.he went through one side once and i went the other side.he had leafs all over him and the mower after 3 passes,after my second pass you could not see them,just like they were sucked up.i do have some blow out but it is very little.just looking at mine i dont see how it could be a pain taking it off,but might be.i mulch all my yards so no big deal for me.

    I run Meg-Mo blades on my 727A with a powered OCDC. The set-up works well with the OCDC open or closed. The closed OCDC really grinds the leaves and clippings to nothing.

    Thanks for the replies. Obviously, the sparse responses tell me that few folks are doing what I want to do (and gl1200a is already doing).

    robbo521 ... Your comments about mounting/dismounting the mulch kit imply that you have not had the opportunity to do the task. Or, if you have done it, how long did it take?

    I see my options as a mulch kit with OEM mulch blades (or Gators), or getting a OCDC and Meg-Mos (or Gators). I understand Meg-Mos take considerably more power to run (gl1200a, confirm or deny?). The 19hp Kaw on my 717A is pretty skinny on power, so the combination of Meg-Mo and 19hp may not work very well.

    I have switched to Gator Blades on my 727A, but I do not have a mulch kit nor a OCDC. I just use the gators to mulch them and discharge them in one direction and then blow off any remaining leaved on the turf with the BR600.

    The Meg-Mo's only seem to pull a little more when at start-up. Once the blades are going it seems to have no effect. I run gators as my OEM blades when I don't have the Meg-Mo's on. The gators add another demension to refining the clippings further while the Meg-mo's really dust the fall leaves and debris.
