generally, different blade can make very big different effect.

for example, the second blade in the first photo, it is small H blade, and the first blade in the second photo, it is also small blade. BUT, because of different material, the second one's price is double as the first. After testing and compare with both of them, the second blade is much better than the first one.

BUT, till now, now customer would like to buy the second blade, because of its price.

By the way, you can find your blade in the first photo.

Thanks for the pics. I believe the 2nd blade in the first photo is the hammer blades I purchased optionally as they were what Betsco was selling and I had no experience... I have not tried them yet as I see no reason it will mulch leaves any better. But I guess I should go ahead and replace them as the current Y blades do nothing to leaves. May change them out tomorrow morning.

My use of the hammer blades was likely borderline abuse. At the time we had been experiencing a feral pig problem and I had significant areas of rooted turf so I lowered the flail to the point it was ground engaging and used it to smooth as I cut. Of course my friendly pigs managed to unearth some rock as well. I busted a fair number of blades. Beyond that I did first time mowing in areas of heavy fern wainaku grass and some guava growth. When I had worn out the hammers and no more replacements, I switched over to the Y blades. I had bought a set of each with spares when I bought the flail. I reason that I'd probably like the results of a hammer type with an edge, hence my wondering about a scoop type blade.

Thank you so much Leonz for your time with this matter. After taking a look at the current blades, I was going to change them out sometime and it may as well be now. I will take a look at what Flailmaster has.

I may PM you with some questions before I commit to purchase anything. I understand the fitment issues you mention on the sides- simple clearance items. But am fuzzy about the slotted knives replacing my current non-slotted knives and creating a lifting effect, as my current knives are not mounted rigidly and are free to move on their axis.

OK NOW HUMOR ME.

removing the spacers will let the knive pairs move
horizontally to the end of the slot mounting to the left
and to the right creating a pair of airplane wings.
when the rotor speeds up because the knive is being
forced outward AND TO THE END OF THE SLOT MOUNTING HOLE by the centrifugal force.

The slotted mounting hole permits the side slicer to become horizontal due the force exerted
by the rotors speed of rotation.

The P51 mustang=
NAVY version with folding wings?
is an oversized example of the airfoil I have been talking about

hope this helps

I'd be very interested in what you get and how it works out as I like Leonz idea. I had toyed with the idea of trying without the spacer, but haven't.

That H in second pic looks interesting. Wonder where I can get to fit my EFGC 175. Never seen the 90 before.

I think till now, the only way for you to get these blade is directly buying from my factory in Chinese. Because of its expensive price, none of my customer buy this model blade till now.

Here are photo which I took when we test this blade, you can see, it have a much sharper blade than the H blade which you are using now.

Yep, that's interesting and looks like it could be sharpened. Hope they become available.

Yes, I'm trying to make it become available in US market.

Leonz, I am going to purchase new, high quality blades as he ones on my mower- aren't. Whether or not they will do leaves will have to be tested. Either way, new ones will be coming when I get them figured out.

I have the mower tilted 90 degrees up- sitting on the front A-frame hitch mount, ready for blade replacement. I have all germane measurements and know what my clearances are. Now I just need to translate my measurements into something workable from Flail-master.

When you say a 3" blade, where is that measurement taken- the total length of the blade assembly- from top to bottom, the distance from the center of the mounting hole down to the end of the splayed "Y" or just the cutting portion?

Some of my current blade measurements:

- 2" length from the very top of the blade to the 45 degree bend.

- And then 2 1/8" length from the 45 degree bend to the end of the blade. This encompasses all of the cutting edge and a small bit of non cutting up to the 45 degree bend.

- 1 7/8" blade width at the cutting area.
