Your question doesn't make a lot of sense, not to mention there isn't actually a question there, however, if you are trying to set up your 54C mower deck according to the book, I recommend taking some of it with a grain of salt.
When I first got mine, I went through it with a fine tooth comb (very little confidence in my local dealership). I tried gettiing the mower deck adjusted just the way the manual instructs. The problem for me was that with the powerflow head on the right side of the mower deck, I actually had to stray from the specs in the book to get everything to work correctly and balanced. There weren't any instructions for that scenario.
As a side note, I ended up nixing the powerflow head and bagging system in favor of a mulching kit. The bagging system for the 2305 is obviously an afterthought and a PITA to install/uninstall. The bagger frame bolts onto the rear tongue of the tractor instead of sliding into a receiver (duh) and you are supposed to be able to apply something like 450 ft lbs of torque on the bolts (DUHHHH!). Ya, ok. Thanks JD, dumbasses.
