Use in my zero turn lawn mower and seems to last alot longer and smooth running compared to Mobil one .

Just rebuilt my mowers zero turn transmissions. Wanted the best transmission fluid for them and I think this is it. Thanks for making this product.

Changed my old fluid and replaced with the amsoil so far so good transmission is working great 👍

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!

Great product !! works even in Hot Louisiana

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

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.

I have 3 Toro zero turn mowers that I switched to amsoil hydrostatic transmission fluid. The machines run very smoothly

I have trusted Amsoil products for over 30 years. Everything I own runs on Amsoil. 2 stroke, 4 stroke , marine , hydraulic etc have all stood the test of time . Never had any equipment failures associated with Amsoil. I wouldn't expect anything less with my Hydrostatic oil. Great product.

I have a Toro Grandstand 40”. This fluid is noticeably better than the Toro 500 premium oil that comes in the unit. More responsive and smooth! Very happy I gave this a shot.

Works great. No issues with this oil at all. I would recommend it to anyone wanting to extend the life of their Hydro Transmission.

Very Satisfied

I have found this oil to preform better and longer in my hydrostatic transmission even with elevated temps and continuous steep hills.

Bought a used John deere X300 with a very noisy neglected k46 transmission. Changed the oil out for this and it drives much better and sounds much happier about life now!
