wondering what factory tip speed is on a 420/430 60" deck as well as 50" deck

who has sped them up? bigger pulley on the gear box?

also what does everyone use for lube in their deck gear box?
some people swear by "redline" shockproof gear oil I've heard of using corn head grease as well. so whats the thoughts on that?

thanks guys

you need bigger pulley on gear box or smaller ones on spindles

I have not tried either yet and don't recall anyone doing it. they do it on 300 series decks though

is your engine running at proper RPM?

cornhead grease is good

do you have the deck baffles still? if not then grass will blow out the front of deck a lot.
