I've found cornhead grease to be too susceptible to heat. It goes too liquid when it gets warm and the steering box is right next to the exhaust.
Lube from tractor supply is exact same stuff as Pennritw at 1/4 the price.
Is it just terminology?
I think of "lube" like 600w oil and "grease" like I use in a grease gun.
Does Penrite make both?
This tractor lube at Tractor Supply
It is NOT. It is the same because I have both in the shop
May I ask, why do we even think we need to change the lube from the 600W to begin with?
