Very good for chain drives on hay balers etc, great for coating things you don't want to rust. Use on linkages for a long lasting effect! Oil tractors always need extra lubrication to keep parts free on brakes, clutch mechanisms, steering, foot throttle etc. I always have a use for extra motor oil or tranny fluid when it comes to freeing parts that need to move. It doesn't take much.
The tachiness of bar and chain oil will help it stay in place kinda like the Lucas products !
