clipping on grass

do most of you guys leave the clipping on the grass when mowing or you guys pick it up??? does'nt it turn yellow after couple of days and make your lawn looks awful??

If I can be included in "you guys" ....

I leave the clippings.  Since I mow high, the clippings don't matt.  Instead, there isn't all that much in the way of clippings.  The clipping fall between the other blades of grass. 

Leave 'em, be lazy! It will help, not harm your lawn.

I do both, actually I don't have a lawn but a country yard. 

Most of the time I let my grass grow very tall, when I cut I collect the clippings for mulch for my garden or for fodder for my compost.

If you don't allow your grass to grow too tall and you cut on a regular basis it's best to leave the clippings, as long as they are not too thick and matting they will  break down and provide valuable nutrients for your lawn.

so how can i leave the clipping on the grass??? don't put the bag in lawn mower??? or change the blade??

I think it would be best to get a mulching blade. although they could just be a marketing gimmick

No bag.  Having your mower configured to do the mulching thing is the best, but if you can't do that, then ... yeah ... just take the bag off.

An important ingredient is to mow high and mow regularly.  Then when you are done mowing you will probably see hardly any remaining cut grass blades.
