TRIAX Trans Zero 20W-50 Full Synthetic Hydro-Static Transmission Oil for Zero-Turn Mowers (1 Gallon)

This hydro trans fluid is the best! It quieted my Toro Timecutter with the cheap ass Hydrogear EZT 2000 hydros. Toro advertises them as "non serviceable" but they are and there's YouTube videos showing how and it's easy to do. DO NOT LISTEN TO TORO or you'll be replacing them. I ruined my left hand hydro and replaced it with a used one. Put this fluid in it and it's super quiet so I did the right side hydro that's still original. It's also quieter than it's ever been! I'll use this TRIAX from now on and plan to do it annually because I have a large lawn and live in South Texas where we mow practically year round. My other advice? Don't buy any zero turn that states they have "non serviceable" hydros. But if you do, service them and use TRIAX for the win!!! This stuff costs less than Toro Fluid and works 1000 times better!!

I used this TRIAX 20W-50 in the hydrostatic transmission of my Cub Cadet LTX1045, and it works flawlessly. The mower runs smoother, quieter, and cooler compared to conventional oil. Shifts are consistent, and I can tell the transmission is protected even under heavy mowing conditions. This oil is high-quality full synthetic, designed specifically for zero-turn and garden tractors, so it gives peace of mind that the hydro system will last. A gallon is enough for service with extra left over, making it a solid value. If you want long-lasting protection and smoother performance for hydrostatic mowers, this is the right choice.

Fantastic hydro fluid. Machine if performing Fantastic after using.

This is the bomb

Use this in my wife’s zero turn cub cadet Ultima hydrostatic was time to change the hydraulic hydrostatic oil. This worked real good. The new oil is full synthetic and makes the hydrostatic drive a lot quieter. She notices the difference. Mom is happy. I’m happy so far we haven’t had any problems. Check the oil. The oil seems fine. The value for the money was decent. Took a little time to drain out the old stuff to get the new fluid in.

Wored great

SUPER FAST, NICE PRICE

When you try to find out what oil to use in your hydrogear transmissions, you get all kinds of suggestions and up till now they all seem to make your transmissions sound like they are ready to crap out with an annoying and concerning whine. We'll this is the only oil anyone should ever use in hydrogears After changing to this oil. I can't hear the transmissions, they just work better than new.
