It is my understanding that Stall Guard is to prevent too high of a load on the tractor within it's operators use and settings. Including throttle setting.
Too high of a load can mean operating implements at too low a throttle setting Or at idle speed.
Load in this context is not carrying or lifting capacity, but it is engine speed vs power and torque requirement.
Remember, diesel engines like to rev. They Need to rev. Read your owners manual and operate it a lot to learn your tractors rev needs. You don't want to redline it but you do want it screaming pretty good under load. Read the owners manual or have the dealer's rep come by and teach you. Or talk to an experienced neighbor. Lugging a diesel is Never good. Give it the gas.
(Don't do this unless under load with a rear PTO implement attached): Set your dash tachometer to display rear PTO. Rear PTO should be 540. When using rear PTO, see how high you have to throttle it up to get to 540 RPM. It's screaming. That is no accident. That is designed into your machine by necessity. Rev it up. But don't get crazy.
Never lug a diesel. If you are even turning the front wheels or raising the loader, give it a bit of throttle. If you don't know what lugging is, Please learn. Lift the loader at idle, the engine sounds like it is struggling... that is lug.
I don't mean to assume too much, so if you know all of this; I post it respectfully. And Disregard.
I always let the tractor warm up until I see one block of the temperature gauge displayed before doing anything.
