I have really been wondering what the thing is with my two TG1860G mowers. One has an FD590V-AS08 while the other has an FD590V-ES08. Something else to note is one has a HydroGear 312-3000 while the other has a 323-3000. Whats the real difference between the engines and hydros? They both have minor differences that I do not know why. One has a badge and the other doesnt even have the molding for a badge on the hood.

Your numbers, besides TG1860G, are all gibberish to me.
I only go by Kubota part numbers XXXXX-XXXXX
The TG1860G, used mutiple changes to the engine and mutiple changes to the HST's during their run.
The serial number tells you which one had what.

Those Hydro gear numbers will tell you 'what's inside' as well as torque, RPM, MPH (fwd/rev) and weight capacity. Just head to H-G website and 'search'.... you'll be able to get complete service manuals, parts list, etc.yes, it may take a few minutes, but well worth the time. Also get the 'how-to-purge' bulletin and any 'tech bulletins' that might be applicable. Knowledge is power !
Now as to why they're different HSTs for the 'same' TG1860g units, it could be one had the original HST replaced with what was on the nonKubota repair guys shelf, or ordered an 'upgraded' version of the HST( physically fits, but 'better' ). I don't KNOW the 'history' of the units,just passing on what 5 decades of 'small engine repairs'. Someone,somewhere must KNOW which H-G HST is the official Kubota replacement HST.
Right now it's a coin toss.....unless BOTH have been swapped in !!!

As far as research I have currently done, the 312-3000 should be the original. I have already tried to find any service manuals for the transaxle and the closest would be the 310-3000 but no exact match. H-G site shows nothing for me! As far as I am concerned, the only visual difference is that one has a drain plug or some sort of plug while the other doesn't.
