The manual states that the blade spindles should be greased every 500 hours. My question is how much grease should each take and what kind. I pumped almost 3/4 of a tube in each one (used almost 3 tubss for all 3) I'm concerned that was too much grease. I basically greased until grease started to spit back out from the relief hole on the zerk fittings, and the middle one until it came out from under the pully on the deck. Thanks for the help. Second question Is it ok to power wash under the deck? I have been doing this about every 3 mows or right after a day of mowing if it was wet.
