Summarize the following:
You can use any kind of rotary-action garden lawn mower to mulch leaves. Two types of lawnmower that are work particularly well for this task are high power mulching lawnmowers and side-discharge lawn mower.  If you want to leave the leaf mulch on the lawn to improve your grass, take the grass catcher or bag off the lawn mower, being very careful of the blade. However, if you want to use the mulch elsewhere, you may want to leave the grass catcher attached to the mower, as this saves you the effort of raking up the mulch afterwards.    {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/3\/3e\/Mulch-Leaves-with-a-Lawn-Mower-Step-1Bullet2.jpg\/v4-460px-Mulch-Leaves-with-a-Lawn-Mower-Step-1Bullet2.jpg","bigUrl":"\/images\/thumb\/3\/3e\/Mulch-Leaves-with-a-Lawn-Mower-Step-1Bullet2.jpg\/aid5012614-v4-728px-Mulch-Leaves-with-a-Lawn-Mower-Step-1Bullet2.jpg","smallWidth":460,"smallHeight":345,"bigWidth":"728","bigHeight":"546","licensing":"<div class=\"mw-parser-output\"><p>License: <a rel=\"nofollow\" class=\"external text\" href=\"https:\/\/creativecommons.org\/licenses\/by-nc-sa\/3.0\/\">Creative Commons<\/a><br>\n<\/p><p><br \/>\n<\/p><\/div>"} If you plan to leave the mulch on the lawn, distribute the leaves over the whole area. Use a rake to spread them out over the entire surface of the lawn. If you're lucky, the trees may have already done this for you!  If you plan to remove the leaf mold for use elsewhere, consider raking the leaves up into a smaller area. That way, after mowing you will have less area to cover when gathering the leaf mold.    {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/6\/65\/Mulch-Leaves-with-a-Lawn-Mower-Step-2Bullet1.jpg\/v4-460px-Mulch-Leaves-with-a-Lawn-Mower-Step-2Bullet1.jpg","bigUrl":"\/images\/thumb\/6\/65\/Mulch-Leaves-with-a-Lawn-Mower-Step-2Bullet1.jpg\/aid5012614-v4-728px-Mulch-Leaves-with-a-Lawn-Mower-Step-2Bullet1.jpg","smallWidth":460,"smallHeight":345,"bigWidth":"728","bigHeight":"546","licensing":"<div class=\"mw-parser-output\"><p>License: <a rel=\"nofollow\" class=\"external text\" href=\"https:\/\/creativecommons.org\/licenses\/by-nc-sa\/3.0\/\">Creative Commons<\/a><br>\n<\/p><p><br \/>\n<\/p><\/div>"}  Alternately, you can leave the grass catcher on the lawn mower and scoop the leaf mold out of there. You may need to keep emptying this, depending on how much leaf litter you have.    {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/c\/ce\/Mulch-Leaves-with-a-Lawn-Mower-Step-2Bullet2.jpg\/v4-460px-Mulch-Leaves-with-a-Lawn-Mower-Step-2Bullet2.jpg","bigUrl":"\/images\/thumb\/c\/ce\/Mulch-Leaves-with-a-Lawn-Mower-Step-2Bullet2.jpg\/aid5012614-v4-728px-Mulch-Leaves-with-a-Lawn-Mower-Step-2Bullet2.jpg","smallWidth":460,"smallHeight":345,"bigWidth":"728","bigHeight":"546","licensing":"<div class=\"mw-parser-output\"><p>License: <a rel=\"nofollow\" class=\"external text\" href=\"https:\/\/creativecommons.org\/licenses\/by-nc-sa\/3.0\/\">Creative Commons<\/a><br>\n<\/p><p><br \/>\n<\/p><\/div>"} You'll want to cut the leaves into pieces about the size of a dime. You may need to pass the mower over the leaves several times to achieve this. Try making the second pass at right angles to the first. If you plan on leaving the leaf mulch on the lawn a one inch layer is ideal, as it will wash down with the rain and decompose over time.  If the mulch is still too thick on your lawn, try reattaching your grass catcher or bag and passing over it again – this will gather up some of the mulch.    {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/e\/ed\/Mulch-Leaves-with-a-Lawn-Mower-Step-4Bullet1.jpg\/v4-460px-Mulch-Leaves-with-a-Lawn-Mower-Step-4Bullet1.jpg","bigUrl":"\/images\/thumb\/e\/ed\/Mulch-Leaves-with-a-Lawn-Mower-Step-4Bullet1.jpg\/aid5012614-v4-728px-Mulch-Leaves-with-a-Lawn-Mower-Step-4Bullet1.jpg","smallWidth":460,"smallHeight":345,"bigWidth":"728","bigHeight":"546","licensing":"<div class=\"mw-parser-output\"><p>License: <a rel=\"nofollow\" class=\"external text\" href=\"https:\/\/creativecommons.org\/licenses\/by-nc-sa\/3.0\/\">Creative Commons<\/a><br>\n<\/p><p><br \/>\n<\/p><\/div>"}  Alternately, you can rake some of it up and use it elsewhere.    {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/2\/2c\/Mulch-Leaves-with-a-Lawn-Mower-Step-4Bullet2.jpg\/v4-460px-Mulch-Leaves-with-a-Lawn-Mower-Step-4Bullet2.jpg","bigUrl":"\/images\/thumb\/2\/2c\/Mulch-Leaves-with-a-Lawn-Mower-Step-4Bullet2.jpg\/aid5012614-v4-728px-Mulch-Leaves-with-a-Lawn-Mower-Step-4Bullet2.jpg","smallWidth":460,"smallHeight":345,"bigWidth":"728","bigHeight":"546","licensing":"<div class=\"mw-parser-output\"><p>License: <a rel=\"nofollow\" class=\"external text\" href=\"https:\/\/creativecommons.org\/licenses\/by-nc-sa\/3.0\/\">Creative Commons<\/a><br>\n<\/p><p><br \/>\n<\/p><\/div>"} It's a good idea to feed your lawn at the same time as mulching it – you'll notice the difference in springtime. A winter blend fertilizer is a good choice in the fall. These fertilizers that have a high proportion of potassium relative to other ingredients.

Summary:
Use a rotary-action lawn mower. Spread the leaves over your lawn using a rake. Set the mower to a height of three inches and mow over the leaves. Leave a one inch layer of leaf mold on the lawn. Feed your lawn at the same time as mulching.
