Replacement blades for MMM on bx1860

[casolorz]

I want to change the blades on my bx1860. It has the 54inch MMM. I don't know the exact model of the mower. I know I do not have a mulching kit but I was wondering if it was possible for me to get some mulching blades and what would be involved with installing the kit? I saw some cool looking gator blades, can I use those? what model? model #90996?

Thanks,

I am in the process of buying a BX2360 with a 54 inch MMM to mow my yard.The dealer has told me that there is a mulching kit for the deck that has mulching blades and a plate of some sort to cover the chute.I have not actually seen the kit but it can be bought through the parts department.I am not sure of the price but it would be different where you are.Hope this helps.

I also have the 54" deck originally bought with my old BX1860. Last I checked, there were no direct bolt on Gator blades for this deck. The closest fitting blades have a larger diameter hole than the OEM blades. Don't recall the size differences off hand. I have read where some guys have cut down a cat 1 to cat 2 bushing to the appropriate thickness so they can use the Gator blades.

Interesting, so what size of blades should I be looking for? suggestions of where?

OK, looked it up and your deck model should be RCK54-23BX. The Kubota blade part number should be K5351-99040. You can go to this link and download a PDF of all the Oregon blades but I just checked and didn't find a match for the OEM blade number.

OREGON brand Lawn Mower Blades

So, you'll have to measure your OEM blade length (diagonally, corner to corner), hole diameter and thickness (maybe not so critical), and find a match except for the hole diameter. I forget which specific bushing is used to close the hole diameter down, but I'm thinking it's the Cat 2 to Cat 1 3PH bushing. I'd love to get a set of gators for my deck (have them on my WH garden tractor) but I have no means to cleanly cut down the bushing to the correct thickness.

Do I need to get any kind of kit with a gator blade or are they all I basically need?

The gators are designed to re-circulate the clippings inside the mower housing for re-cutting with the vertical, back of blade "wings" without the need for a kit or baffles, etc. I use them on my Wheel Horse and I definitely notice the clippings are smaller and therefore disappear better into the lawn.

I wonder if this will work for me without having to get special bushings

Here is a document that a fellow TBNer compiled awhile ago that I saved for future use. It may help you in your search.

Edit - This may not help now that I look at it closer. The blade sizes are for a 60" deck.

Go to www.jackssmallengines.com. According to the part lookup on his gator blade link, part #396796 should fit your MMM. Call them, I did to be sure his G blades were right for my LandPride deck. His prices are good also and I received the blades in 3 days from order.
