If what you have is a MOWER (as in lawnmower) it sounds like it idles and runs but when you engage a load it dies.... This is usually caused by something caught preventing the blade from turning or if it has powered wheels something wrapped around the axel. NEVER WORK ON A RUNNING MOWER, fingers are a hassle to reattach.

To adjust the gross setting it involves removing the back cover and working near the high voltage flyback with the power on. ONLY USE PLASTIC OR INSULATED TOOLS (I ALSO WEAR RUBBER GLOVES) CRTs can KILL.... There should be three plastic potentiometers with slots cut into them for a small flatblade. On really old CRTs they also used small magnets attached to the sides of the picture tube as well. Adjust the monitor slowly. If possible have someone else watch the picture while you adjust so you can insure not touching a live board. You life is not worth an inch of black screen.
