That might work, Duane. Actually, the last time I did it, I used chain lube. When it dries out, it leaves a dry lubricant, so I think it is similar to the waxy grease. The worst sticking I have had was in the first week I had my tractor and the forward pedal would stick like I had cruise turned on unless I stepped on the reverse pedal. Now, after 200+ hours, the pedal will sometimes just return slowly and that's when I get out my can of lube.
As you mentioned earlier, my tractor will creep if it's not on level ground. If I need to keep my bucket raised when I get off the tractor, I always set the parking brake or drop my boxblade if it is attached.
