Low idle: 425 RPM. High idle: 1595 RPM. But read on: Think about it. The tractor was running fine with the governor set up the way it was. Unless you changed the adjustments already, the odds are re-adjusting it won't make any difference. ALL a governor does is help the engine run at a constant speed as load varies. Period. They rarely if ever cause rough running. An exception: if the engine speeds up and slows down and can't seem to make up its mind what speed it wants to run at, the governor is often at fault. This is sometimes called hunting and can often be adjusted out. Try this: with the engine off, grab the throttle rod. Move it through its range. It should be very free with little resistance. Now start the engine. Grab the throttle rod again (watch those belts!) and try to move it. You should notice greatly increased resistance. Increased resistance? Your governor is probably doing its job (unless it is hunting, as described above) and you should probably not mess with the adjustments until you are CERTAIN nothing else is wrong. No resistance? The governor is NOT doing its job. It needs to be fixed before being adjusted. Does the rod move back and forth of its own volition? The governor is hunting. Adjust it per the manual; if it STILL hunts, you may need a rebuild. I don't bet; but if I did, I'd go dollars to donuts that unless you're experiencing hunting, your problem isn't the governor.
