John Deere 2520 Zerk fittings

[Petroman1]

Having put a few hours on my tractor I thought I would look at the grease fittings for the first time. So I pulled out the manual and only found 3 zirk fittings listed. This didnt seem right so I started to look around and here is what I found.
3 listed in the manaul for the front suspension (not pictured here)
3 under the foot board on the left (brake) side.
2 on the Fwd/Reverse foot pedal linkage
1 on each side for the MMM Independent Lift linkage.
I also did the FEL and those seem pretty straight forward.
I see in the manual it states to do this every 50 hours with normal use. Is that standard practice or a bit more often? :confused2:
Attached are what I found.

After a while, you'll get use to the JD manuals not being exactly accurate and out of date...it took me a while but i did. I only grease once a year, each time i do annual maintenance. unless you see some spindles and other this that seem dry.
