Electric Lawn Mower Mulching Blades/Attachments?

Some years ago, I bought two mulching mowers. A jonsered walking mower, and a stiga ride on, as we had several acres of lawn and disposing of the arisings was a constant issue.
When new, with the blades sharp, both machines were unbelievably effective with the grass neatly cut and the cuttings seemingly consumed.
I expected, and would have accepted, very small clippings to be visible, but there was no evidence that the cuttings had not been transported away.
When the blades became dulled through use it was not the same story, and it could appear no different to using an ordinary rotary mower without a collector.
I quickly learned to sharpen the blades.
If the machine is kept clean underneath, washed proper clean after every use, and the blade kept sharp, mulching is effective.
Thats just my opinion though. Isn't here a gardening forum where this might be better addressed?

 

I think the key is more frequent mowing so there's less debris to deal with. I used a Flymo for years and only ever raked the clippings if the grass had been long before cutting. Now have a Bosch electric rotary and that came with a mulching plug.

 

Don't know as never used it. Aways have the grass box on now I have one. (Flymo didn't have the option}
