Sorry Q/S-farmer and I don't mean to just sound critical, but from the 3rd picture in Post 6, it doesn't look to me like the Meg-Mo does a good job of cutting at all. It looks like the Meg-Mo just lays over the heavy grass rather than chopping it up like your rough mower.

I don't envy your task of keeping that stuff cut down though. I have a small patch, maybe 50' x 50' of it and find it's almost impossible to cut in one pass. In fact, I've already burned up the clutch in my Hus.54" mower once trying to do just that.

Can you tell me what causes the striping? I have that problem too, and would like to see a smooth cut all the way across.

Thanks for your post and the pictures.

QSFarmer, a good flail mower with hammers wouldn't even know it was cutting any of that and it would cut it as low as you would want it to be cut. Most of that stuff is way more than you should be cutting with your mower. I have one question for the MM. Do they have mulching blades for that setup? I run mulchers on both of my JD ZTs.

You are certainly testing them in a manner in which finish mowers werent designed.

My the nature of the short deck, and relying on the suction created by the blades....finish mowers just dont do well on tall grass. They tend to just lay it down and by the time it stands back up you are already beyond it so it takes several passes to accomplish what a rotary cutter can do.

MY understanding of the meg-mow blades were to replace blades in standard mowing applications....like your weekly mowing of a lawn.

The jury still seems out on just how good they are at replacing a standard blade. On dedicated mowing forums.....they dont seem to get much love. But I think half of that is people just resistant to change. Why try and fix what isnt broken. And I think the other half is simply the cost.

My opinion is they have the ability to leave a better cut and/or at a faster ground speed since you are effectively doubling the number of cutting surfaces. But Alot of guys (and I have done in the past) is simply stack two standard blades on each spindle.

MY concern is clutch life. Either with the MEG-mo's or double blades....there is alot more rotating mass to start and stop everytime the deck is engaged. But according to the professionals on dedicated lawn forums....some people are saying that there just isnt enough of a improvement to be worth the hassle. And some say they just dont stripe or distribute clippings as well.

For me the pet peeve would be the cutting height. It annoys the $hit out of me when the numbers on your mower height dont match reality. I have worked on toro, scag, exmark, bobcat, and kubota mowers. With few exceptions the running theme seems to be the mowers cut 3/4" closer than what the setting says. IE: set it at 4" according to the mower and actually measure it and its at 3-1/4. But they werent all exact. A few were 3/4" off, some were 1/4" off, some spot on, etc. Which makes it challenging when I services a dozen mowers for a landscape company. When they are set at "4".....they need to ALL cut the same height. Not really an issue for a homeowner, because they can use the number simply as a reference. But for a mow company.....trying to explain to the people actually mowing that "this" mower needs to be set at 4-1/2 and "that" mower needs set at 4, and that other mower needs to be 4-1/4, etc etc.

Some of the mowers had enough adjustment to make them spot on. Others didnt without other modification, like changing the thickness of blade spacers between the blades and spindles, or slotting the adjustment holes to give a little more travel.

On a mower like my scag.......in order to get it to read true (it was 3/4" off), the factor adjustment only allowed me to get 1/2". so I was still 1/4" off. So I shaved 1/4" off the spacer between the spindle and the blade. Switching to this blades would throw that off again. OR like if I could convince a mow company to buy these to "try" on a mower....now the deck calibration would no longer match the rest of the mowers in the fleet.

The double blade thing has always eluded me. Stacked blades are effectively cutting the grass twice or the top blade is not cutting at all. So that blade is basically along for the ride and putting additional load on the mower. It's sort of like having a bush hog set up incorrectly with the front higher than the back making it cut twice.

i strongly considered these, over a set of gators, my mother is a fanatic about clippings, starting to think i prolly should have got these, not thrilled about the lack of the star pattern, curious to see if that bolt is going to loosen or the assembly spin

The double blade has a few advantages.

1. with one blade higher than the other....you are effectively making the clippings smaller. Dont think of it as the top blade not cutting at all. Rather the top blade cuts the grass higher than you want, then the lower blade cuts it again. ITs like mowing the lawn once, then dropping the deck a notch and mowing it again, just in one pass instead of two.

2. More blades also means more suction if you have a grass that dont like to pop back up after it is ran over

3. What the lower blade cuts and gets tossed up, the upper blade comes around and makes it a bit smaller.

4. If you have ever mowed too fast and leave strips uncut, or the dreaded dandelions or buckhorn plantains that like to duck and pop back up after you have passed unless going real slow....double blades help tremendously.

I used to mow exclusively with double blades when I had a tough to mow lawn, with wirey grasses and weeds. Yes its additional load on the mower and harder on the clutch. I have slowly been working on the lawn to rid it of noxious weeds and the issues I was using double blades for. So now I am just back to grass.

Same with the bushhog. Sometimes it IS desirable to mow with the back lower so you get a double cut and finer clippings and a nicer appearance. Just depends on the job. To each his own

I dont think lack of star pattern is an issue. MOST commercial mowers just have a round hole and rely only on bolt clamping force. The star pattern or blades that have an index pin are usually something only seen on residential grade mowers.

The commercial mowers do usually use a 5/8" fine thread bolt. I wonder if the retaining bolt is smaller and has less clamping force in spindles that use a star pattern??

Which blade cuts first is dependent on which one gets to that particular blade of grass first. I run mulchers so I don't have any clippings or discharged grass.

Thanks for your testing. Please update this thread as you continue to use them. Are there sharpening instructions with them?
