I found out the Zerk wasn't bad after I pried it out as it took grease just fine once removed. I've read that JD put Zerks on some spindles just for show & that the spindle bearings are actually sealed requiring no grease even though the owner's manual says to grease every 50 hrs. This machine only has 160 yrs on it and those 2 spindles have never been greased. Does anyone know if these spindles (OE) need to be greased? If so, what's my next step? Disassemble the spindle? (I've seen online vids on the process) Take off the spindle(s), take it to JD & have them grease it? I'm hearing that a new spindle is only about $60. Thanks.
