The rake as we know it today was invented in the year 1874 by a guy named Edmund Brown.
Edmund Brown got a patent in 1874 for the first rake he invented.
The first patent for the rake was given to Edmund Brown in 1874 and other people have redesigned the rake but Edmund Brown was the first to invent the rake.
There was probably other versions of rakes made way before that time.
But the modern rake we use today was not in existence until at least 1874 which was a long time ago.
1874 was 146 years ago as of 2020.
Now we have many rakes and even pull behind rakes that make raking the yard a lot easier than it ever was before.
