Older cars with open drive shafts had grease fittings on there u-joints. The only way our u-joints get lubricated is from oil or light grease being splashed around inside the housing. Cornhead grease will settle back into the bottom of the housing after the movement stops. Heavier grease will not do that.
I would think that a corn picker would use oil in its drive transmission. The units (gears) or (gearboxes) running the cutters I believe is where the Cornhead grease is used. As in you lawn tractor.
Just my view, I’m not a tractor expert.
