I have a Scag Turf Tiger I just bought and will do all of my own maintenance. In the owners manual it says to use a lithium grease on the deck spindles and also on the driveshaft. WHat brand and type do you guys use. I am unsure exactly which greases on the market are lithium. I currently have in my grease guns Lucas Xtra Heavy duty(blue), that I think would be correct for everything but the deck spindles and driveshaft, and in another gun I have Lucas Red n Tacky(red) that I believe would be sufficient in the spindles and shafts. If these greases are not correct, what type should I use?
