On my old LX288 I remember the dealer telling me to give the deck spindle bearings two shots of grease about once a month. I forgot to ask him about the new X320. I see in the manual it says once every 50 hours or annually. That seems to be a long time between greasing.
I mow about 3/4 of an acre, and it takes about an hour or so. So, around every 4 hours on the mower, should I give the mower spindles a couple of shots of grease as I did on my last one? I never had an issue with the bearings, but I certainly don't want to over grease them either.
Also, I normally use Valvoline Synpower synthetic grease because... well, I use it on everything else... ATV, trailer bearings, u-joints on the 4Runner, and anything else that needs greasing. Do you guys prefer to use the JD synthetic grease, or do you think the Valvoline is fine. I know it's probably overkill on the axle pivot, axle spindles, and the lift pedal, but what the heck... that's what's in the gun.
Anyhow, wanted to get your recommend grease and greasing intervals, or what you guys do and use.
