Being as most lawn mowers are made of some kind of metal,
they should be taken to a local recycling center.
Thus proving raw material fur future use. If the mower is still in working condition for the most part many small engine shops still take trade ins on new equipment, probably wont get any cash but will get a brake on that new one you've been looking for.
take apart a lawnmower that is worn out and take it to a scrap metal place.
As in grass on a lawn? Lol....no.
of course they can
use a blower or rake to get the clippings
i dont know this variety but most grasses can spread by clippings
Yes and no. Some modern lawnmowers are designed to 'mulch' the grass. That is, when used without the grass collection box/bag, they chop the clippings very fine and dump them on the lawn as you mow. This, if done every second or third cut, actually helps the lawn by feeding it. The grass needs to be quite short already to do this. If it is too long the mower will continually clog. If you leave heavy grass clippings on you lawn you will prevent light from reaching the grass and therefore stop photosynthesis and the grass under the clippings will die.
grass (or any plants in general) is organic.
The grass clippings provide a great source of nitrogen for the grass. It is best to leave the clippings. It does help retain moisture. The grass clippings can even be used as a mulch for plant beds.
If it's a pile of grass left on the lawn after you mow it, cal it a clump of grass.
Grass clippings and other plant material can be returned to the environment for recycling if collected in a pot. This is keep the earth healthier.
A compost bin, heap, pile or pit and an incinerator are respective places where grass clippings and weeds can be disposed. Grass clippings can be left in place as a natural fertilizer recycling nutrients back into lawns or removed to the cultivator's own compost container or corner or the neighborhood center (if there is a block-wide effort at recycling kitchen scraps and lawn litter). The individual who burns weeds must be in compliance with local fire regulations and in contact with dispatch and the person who composts needs to sort diseased, germinating debris and weeds into heavy plastic bags for the fire pile or the landfill.
If there are still alot of wet grass clippings on the ground I would not recommend it. Fresh clippings can easily impact a horse and cause them to colic. Remove the clippings or allow the clippings to dry throroughly before you put a horse in the pasture.
The Answer to your question is composting
