Some people call it a frog and some a mold board. When I worked on the Weyerhaeuser railroad we had a tool for putting cars back on the rails after a derailment that was called a frog. I don't know where the name came from. I learned it from working with older the generation at the time.

Probably a regional thing but what I'm used to referring to as the frog is the heavy piece at the bottom of the moldboard that the cutting edges bolt to.
If the frog becomes your cutting edge you may want to train the operator to keep an eye on GET wear...
No clue why it's called the frog though. Interested to hear.

Its the very lower area under the blade that supports the cutting edge, it looks like webbed feet of a frog.
It is the same area that will fill with dirt when back blading that sort of lifts the blade, and helps cause less wear than pushing forward.
Mold board? Isn't that the whole of the face of the blade?

done a bit of research,the frog is a part of a horses hoof , located on the underside,which should touch the ground if the horse is standing on soft footing.So you could say on a machine its the part that holds the cutting edge [ hoof on a horse].definition,its a thick metal base,shaped like a block or triangle .attached to the mold board[welded]. Function,it gives the mold board support. giddyup

Frog is also used in old RR terminology for parts of the rail switch.

"Bulldozer" in a RR forge shop is a very different machine.Yeah proves one use of nomenclature for one application may not be the same on some other application. So ya can't say its this on this because its that on that.
