How to remove carpet rubber foam from floor?

I’m trying to remove a carpet backing.. It is a rubber foam backing and is glued the carpet cement…I pulled capet up..But foam backing stayed…I have a sharp small scraper… I want to put down flloe tiles and I have to have plywood clean..It is a very long acking process on my old acking back and knees….Does anyone have the right way to do this??

They make several types of stand up scrapers that will do the job.Some with sharp replaceable blades and some with a heavy duty all purpose blade .
Trying to use any type solvent is way to messy and dangerous and wetting it wont get the glue up. GL
