Review: Saved my Toro TimeWaster Hydro - 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!!
Review: Excellent Synthetic Oil – Perfect for My Cub Cadet LTX1045 - 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.
