What is the easiest way of getting gravel out of grass?

Fine rake!

It's difficult to tell from this picture but it looks like it might be pea gravel. In that case, you rake is probably too wide to pick it up. Try a bow rake also known as a rock rake. You can flip it over and use the backside as well.

A very long bristled push broom might help.

Someone mentioned a big fine rake and that's where I would start. So sorry you have this issue!

try a shop vacuum it won't hurt the vac and you can empty it out when it gets full

Use a bow rake.

Rake it out

You will have to use a rake and a lot of manpower.

This maybe a bad idea, but what Abt using a shop vac?

I don't know how much or how big the gravel is. If it is too much to do by hand, I se would use a fine rake, but you would have to careful to not rip out your grass with the rake.

Try the rental section at Home Depot or Lowe’s if you don’t want to purchase a tool, they might have something that will work. Bring a few pieces of the gravel with you to the store.

I would hesitate to use a shop vac, you may get some turned sideways and block the tubing, we just went through this when my husband accidentally sucked up a couple of wine corks with the upright vacuum cleaner. What a mess.

Your picture looks just like what we will be going through when the weather improves, I plan on using a rake with teeth spaced closely and are solid metal, not anything bendable like plastic tines. You could try to rake them into a dustpan with a long handle and then dump them out.

Use a bow rake which has wide tines but won't pull up anything but the thatch accumulated around the base of the grass.

A leaf rake to get the big stuff... then use a big shop vac

I had this problem once, I used this guide to put gravel on the soil and create some paths. But sometimes it gets out of control. And here are the solutions that helped me:

Use a landscape rake (with flexible tines) to gather up the bulk of the gravel. Keep the rake at a slight angle and use gentle, short strokes to avoid harming the grass.

Also, shop vac he should help

Why not build a bit of a wall or fence around the edge of the gravel?
