2010 cub cadet transmissions

I'm wondering if these need any maintenance. They are starting to make some noise. Is there anything I need to do to them? Oil, grease etc? I have the book on how the thing goes together but nowhere can I find anything about tranny maintenance.

If they ave just started to whine it is prudent to change the oil.
Clean oil and one grade thicker

I have a 2009 Cub Cadet with a Hydro Gear 310-0510 transaxle and I have removed it to change the fluid due to some noise that it had been making. The noise was not whine, but rather a moan that only occurs when the pedal is first pressed, and it is intermittent at that. Needless to say, after changing all of the pulleys, the drive belt, adjusting the brake and changing the fluid, the noise still persists. I will say that the oil was black when I checked it (about 225 hours use) so I went ahead and drained and re-filled with plain old 20w-50 motor oil. The unit still runs smooth and strong, just makes some noise. This issue is beyond me. Speaking of oil, I was at Autozone today and saw that they had some off-road 20w-50 motor oil that was listed as being "high zinc." If memory serves me correctly, higher zinc content is desirable in oil used for hydrostatic transmissions? Either way, good luck on your journey of figuring it out.

Thats some great info. I have the deck off atm. Do I need to remove the hydrostatic transmissions to change the oil? Of can I do it on the machine? Really appreciate the help.

Its not working for me.

Went to Hydro-Gear and looked for ZC-AMBB-4DDB-3RPX. Didn't find the service manual from that number. I did go through all of them and I think I found out it was a ZT-2100 or ZT-2400 RZT Not sure if this is correct or not.

your unit is either a ZT-2100 or Zt-2200 unit is to be removed from mower, remove the fill plug and drain through fill plug. add oil until within .75-1.5 inches from the top. purge air from unit, and run for about 1 minute and recheck level. According to Hydrogear. Approx 54-56 ounces of 20w50 oil
