A dull mower blade will "tear" the grass instead of "cut" it. The jagged blades of grass will dry up and cause your lawn to look brownish or even yellowish - much like when cut grass clippings turn from green to brown/yellow as they dry up.
Check the oil/fuel mix and make sure you have it mixed to the correct ratio. Else, try raising the blade on the lawn mower. If you have the lawn mower blade too low, mowing tall grass, it can make too much work for the mower and will cause it to overheat.
the most common cause is a dull blade, resharpening / replacing the blade should solve this.
i think to cut the grass duhhh
blade needs sharpening,or belt is slipping for mower deck.
It shows that the blade is not that hard since grass can make the blades dull.
sometimes it pulls the grass up cause the soil is loose
The part that says grass side. The wings go up
If your push lawn mower is not working as well as it used to work, you might be thinking about replacing it. Before you purchase a new push lawn mower, check your current mower's blade. Over time, lawn mower blades grow dull and no longer cut grass as effectively. If you take your lawn mower blade to a hardware store that offers a blade sharpening service, you can usually get the blade resharpened for a small fee. With a newly sharpened blade, your old lawn mower could be working just like new.
If the engine is running at proper speed the outside edge of the blade is moving at 1900 RPM, at those speeds only the first two outs side inches of the blade are doing all the work.
The deck on a lawn mower is the shaped metal shroud that keeps the spinning blade(s) from being exposed to the user during operation. Many manufactures use the shape of the deck to create a mild vacuum that draws the blades of grass up toward the mower blade(s). After mowing the lawn, some grass will be stuck on the underside of the deck. If the lawn is somewhat long and wet, the grass will build up on the inner surface of the deck to a point where only the blade(s) have clearance. This stops the deck shape from performing its designed function. Deck cleanout is performed while the mower is NOT running. Turn the mower on its side and scrape the excess grass from out of the underside of the deck.
I actually leave the clippings, but I have a mulching blade on my mower which cuts up the grass a little finer that non-mulching blades. If you have a mulching blade and leave the grass cuttings they just decompose but if not and you leave too much, it could cause some issues, more thatch, etc.
1. It depends on the lawn mower, if its a ride on you shouldn't because you can make tyre marks on the grass. 2. you secondly shouldn't because the mower blade doesn't function as well when its wet, because the mower blade can just bend the blade of grass and your lawn won't look as good as it would if it was cut dry.
