Diskbine blades for lawn mower?

[SGBotsford]

I have issues with lawnmower blades. Couple times a summer, I take the blades off, sharpen them on the belt sander, and put them back on. There's only two chances per revolution of the blade to get a grass stem, so if I mow fast, I do a crappy job.

Occurs to me: Anyone put diskbine blades on a finish lawn mower? I've seen the blades on sale for 60 cents each, and each one has two edges. Instead of removing and resharpening, just flip or replace. And you have a lot more edges that have a chance at the stem.

Some years ago there was a company that designed something similar to what you are talking about. Never went anywhere.

Google meg-mo.

I'm too cheap. I use 2 sets of blades in each spindle. Blades perpendicular to each other and tack welded to hold them 90 degrees apart.

Gotta have a powerful mower to spin them though. Got 27hp on a 61" deck and I certainly wouldn't want any less power or more deck.

Don't mow fast,that's no good regardless of blade. If your time is simply too valuable to slow down you can afford a Z-turn that can go lickty-split.

I have only had issue with mower (lawn mower or finish mower) of giving poor cut, either running engine too low rpm so blades are not turning as fast as they are suppose to or cutting too heavy grass normally meaning too tall or with blades that are dull or worn out. I also have a 37 hp mower on a 61 inch deck and with standard blades even in heavy grass it cuts great, but still have to slow down once in while due to the type of grass.

I have used my rear finishing mower to cut a field of coastal that was sprigged this year and when I cut as instructed at 7 inches high no issue but at 12 inches high it just could not handle that much under the deck.

It make's all the difference in the world when mowing tall grass if deck is a mulching type rather than one that eject's grass as it's cut. I have a 6' Rhino on a 60hp tractor that alow's going to a higher gear if defector chains are removed from deck. It will also throw objects out at sonic speed if chains are removed,I don't mow much without chains in place.:ambulance:

Well, I've got a Grasshopper 725D, but I'm doing 12 acres of tree farm. With it at present it takes 16 hours to do all the mowing.

I like to mow high most of the time -- 3.5 inches.

I had my 6 foot john deer MX-6 chuck a baseball sized rock out the back. Went about 300 feet.

My grasshopper ejects the grass, but even with high lift blades ejects it as huge wads. This was pasture at one point. Lots of brome, quack grass, some alfalfa. Even mowing weekly it's 6 inches high in the coarse grasses where the grass is getting watered by the seepage from the irrigation system.
