Help with my four wheeler

So i dont have a video right now. But basically the problem (info on the four wheeler is in my garage tab) is that when the four wheeler has been idleing for a while and i give it throttle, it bogs really badly, and if im doing things like plowing (its main use) it bogs really badly when im on and off throttle alot. Ill try to get a video for more clarification but if anybody knows a good fix that would be helpful. Thanks.

P.S. i have tried raising the idle speed. That did not work.
