    ZTR 20W-50 Hydro Trans Fluid
    By  BRYAN,  a  Verified Buyer  from  Southern Indiana  on  August 31, 2021

    Describe the issue

    Good stuff - I was always surprised that my two ZTRs (Great Dane & Country Clipper) specd 20W-50 motor oil for the hydraulics, but it worked for 10+ years. I was starting to have a whine and a small leak in the CC ZTR. I saw this and liked that it was 20W-50 and specifically for ZTR hydros. Switched both to this and they run cooler, seem more responsive, and the whine and small leak have went away.

    Bottom Line
    Yes, I would recommend this to a friend.

    I can say this is the best for my mower! Used it three years in a row and It takes the heat of summer and never overheats causing the reservoir to overfill. Operation of my mower is very smooth also. Another Great Product

    Fixed the problem
    By  DAVID,  a  Verified Buyer  on  July 07, 2021

    Describe the issue

    Used this in my 8 year old Zero-Turn mower that wasn't pulling like it should. Took the trans-axles out, turned them upside down to drain the old oil to change it. Refilled with Amsoil Zero-Turn Hydrostatic Transmission Fluid, reinstalled the trans-axle, bled the air out of the pump a couple of times. Since there is no way to check the oil in it without taking the trans-axle out of the mower again to check & refill it after bleeding the air out. I removed & installed it a second time. After I was all done with bleeding the air out and getting the oil to the right level. The mower ran like it did when it was new. I would recommend this, without hesitation, to anyone who is servicing a trans-axle or hydrostatic transmission.
    Bottom Line
    Yes, I would recommend this to a friend.
