OK. This is about a Cub Cadet rider. Sorry, it's related though. Sue me. This is about manufacturer instructions and how they might be wacko. There is a lot of discussion about this on here (fluid changes, etc.) I needed to sharpen the blades on my (sorta new) Cub Cadet XT1 so I googled it to see what tips I could find. The first thing I found was an instruction from Cub Cadet telling me my blades should be REPLACED EVERY YEAR. Not sharpened, replaced. If that isn't stupid I don't know what is. Must have been mandated by the sales department. Then I find a video telling me to completely remove the deck to change the blades. F that, put the front up on blocks and reach underneath. Again - stupid IMHO. Must have been mandated by lawyers. Also ... you need to buy this special tool to hold the blade in place while loosening/tightening. I have a special 2x4 segment I use for that. Seems to work pretty well. Ha! While I'm totally off topic. The spindles have no grease fittings? WTF are you kidding? Again, someone in parts sales mandated that to sell spindles? They already sound bad.
