    Not the Honda blade.
    But I've run dual blades on most of my 21" pushers for a good number of years.
    Smoother cut, but a bit noisier. You can also feel a little bit more flywheel effect to the mower while running.
    Make certain the retainer bolt is long enough for this trick!
    Threads in the crank hole and on the bolt need to be in excellent condition.
    Either tack weld a couple of cross bars on the lower blade so the it doesn't spin under the top blade.
    Or a couple of bolts in the "universal" drive slots (where the drive protrusions on a blade adapter usually fits).
    The blades end up at 90 degrees to each other.
    Rainy here or I'd go snap a couple of pics.

    Buddy of mine gave me a Honda Harmony HRB 215 Hydrostatic with rear bagger last year. I parked it in the shop...need to get off my ass and run through it, tune it up and let it do its’ thing. It ran when he gave it to me...he migrated to a rider and that’s how I inherited it.

    I should of added I want to try this on a 22" Toro. The hub assembly has a cap on the bottom that sandwiches the blade as it is now.

    Nice unit. They still bring around 150- 200 in my area.

    And I guess while I'm at it I'm looking for a really good high lift blade so I can throw come clippings like crazy on a Lawn Boy I want to set up for tall grass only.


    Where is Joe @Onan18 when ya need him.

    I still have my Honda Harmony 215 mower from 1995. Runs well. I love the double blade setup. I have been mulching since I bought it. No grass clippings whatsoever.
    But I thought about adopting the blades to other mowers, just never had the need to.

    Looks exactly like mine. Plastic deck. I wore out a set of wheels. Only things I have replaced other than blades, and tuneup parts.

    Stens high-lift blades work really well, I've used them on a few mowers. One thing I wonder though, is do high lift blades cause spinach to build up on the bottom of the deck faster?

    I tried to watch a video Stens made about their blades but the audio quality sucked more than Bells first phone call.


    I'll deal with the spinach I just need a set up launch some *s-word.

    Ive seen some rider blades that I might try.......

    If you are trying to mulch with high lift blades it might. High lifts are meant for bagging or discharging.

    Blades crossed to mount1.JPG bolt location detail1.JPG If you aren't the type of person who pre-walks the yard and looks for debris and hazards,
    then This is NOT the kind of thing to do to your mower.
    You'll likely end up with a damaged mower and possibly hurt yourself severely
    IF you are that person who hits roots, rocks or stumps toys, garden hoses (or shoes), then you have NO business trying this.
    It will break loose from hitting objects.

    IF you run two blades, you have to keep an eye on the retainer condition!
    This means checking it before every use.
    Always keep a stock of center bolts and fresh washers on hand to replace when they look a bit worn or the washers start to get cupped looking.
    A quick touch up of the edge is good while you are checking things, is good also.

    Here are a few of the blades I've tried over the years.
    You can see how I used a couple of bolts for anti-rotation when stacking two blades.
    Notice how the nuts area set so that the flats are parallel to the blade sides.
    Just drop a center bolt into the stacked blades and then install the bolts to fit the needed spacing.
    I think the blades with a bit of steel tacked to them (tack weld on the blade edge only) are all under the mowers somewhere now.
    Yep. A little bit of M.A.D. ..mower acquisition disease here.

    The "wavy" mulching blade and the "gator" blade seemed to be a pretty good combo after trying several types.

    The "S" shaped one didn't seem to cut any different (better or worse) in my grass. Don't recall if it was any quieter or not.

    The, high lift wing, blade would load the engine noticeably in heavy grass.
    It also seemed to stir things a bit too much and actually did a poorer job of loading the bag on a Snapper 21"
    That side tube, from the deck to the bag, seems to be a bit of a choke point I've discovered.
    If the grass was lush, the tube flow would be bad to clog when running a high air flow.
    Seemed like the bag would let a certain amount of air through and then above that point, the flow and grass clippings began to stall and choke in the tube.

    I ended up using a Murray rear exit deck, to bag leaves.
    edit: I still use the Snapper for mowing grass though!
    (Whole nother story on deck mods to get rid of stringers)

    Eventually a backpack blower curtailed my using the mowers to grind the Fall Season leaves.
    The blower is why things have gotten a bit rusty from sitting unused.

    eh. Using the crossed blades just sort of came from spending my life around various cutters, saw blades etc and looking at the surface finish.
    I had seen some discs under a few mowers, with multiple cutting tips.
    Just kind of occurred to me to try and see if the crossed blades would spin ok or possibly get into an oscillation from each others wind or some other issue.
    If you've ever had thick or wet grass buildup under the deck and cause the blade to hit, the crossed blades will likely be worse.
    For heavy grass, knee deep kind of stuff I recommend staying with the single blade.
    The heavy cut could cause the blades to shear the bolts or try to bend across them.
    IF the bolts break, you run the risk of things spinning and possibly getting loose.

    Also takes more power to pull the twin blades, so just not a good thing to bush hog with!

    Did somebody say running doubles?

    Or making high-lift into super-lift blades?

    If you have a well-designed deck and an engine with enough torque, I have good things to say about both. o_O

    You must snap belts with those double blades, No?

    Nope. 5/8" width belt on the 54" deck and 1/2" width on the 46" deck. Will it eventually wear things out quicker? Yes.

    I even ran over my Wife's gardening hand rake with the 54". Wrecked the rake. Put a ding in the blade and pushed it up against the other blade. Looked like the Honda doubles, but stayed balanced and I cut two more times with it that way before servicing the deck.
