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.
One particular customer I have figured changing the engine oil to Amsoil would be enough. I challenged his to change the zero turn and he remains totally impressed. His statement to me was: How can these products make such a difference? I just simply stated: they are Tested! Tried! and True!
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
Yes, I would recommend this to a friend.
Fixed the problem

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.
