I am befuddled and confused. I inherited an X540 three years ago that my father bought in late 2007. Today the battery died and I replaced it. Then I decided to lube it, which I do regularly as per the book. However, as I went thru the lube points in the book, I again failed to find a zerk fitting for the lift pedal assembly. I have never, ever been able to find it and tho the picture shows one, there is no fitting on the round assembly! Looking and feeling all around I still cannot find one. I have a 54" deck and do not use a snow blower. Am I missing something or is it possible my X540 does not have a grease fitting for the lift pedal assembly? Every time I grease this machine I scratch my head in wonderment and today found this forum after trying to find an answer. Any help would be appreciated.
