Quick oil viscosity question.
I’m repairing a couple Gravely Pro Turn 260s. It looks like one as a Kohler and one has a Kawasaki engine.
Both have high hours on the engines.
Normally I use 10w-40 for summer mowing in mowers but I see online it says some people recommend 20W-50 for the Gravelys. What are your thoughts?
