The deck should have grease fittings on top of the spindles, just above the sheaves (pulleys). There's also a grease fitting on the belt idler on most JD decks. You may have to remove the belt covers to see if yours has that fitting and to access it.

You can order manuals from Deere, either printed or on CD. As far as downloading Deere manuals goes, there are no authorized versions available for download that I'm aware of.

 

FYI, I found out when I stopped at a JD dealer that here are no grease fittings on the spindles. Just another example of the JD enginneers--or more likley the bean counters there cheapening the JD name by a stupid decisions like this. :banghead3 BTW, the relacement spindles do have a grease fitping.

 

Interesting. The parts manual shows a grease fitting on each spindle.

 

My LX188 48in. deck has grease fitting on the spindles. Have you taken a rag and wiped the ends to remove the dirt and grass that builds up, they are small nipples on the end, got 2 decks and both have the grease fittings.
