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. ## Features - Broad OEM Compatibility: Compatible with leading zero-turn and stand-on mower brands, including Ariens, Bad Boy, Cub Cadet, Dixie Chopper, EverRide, Exmark, Ferris, Gravely, Husqvarna, Hustler, John Deere, SCAG, Snapper Pro, Toro, Walker, and Wright. - Direct OEM Fluid Replacement: Replaces all OEM hydrostatic transmission and drivetrain fluids that require a 20W-50 or higher-viscosity grade, simplifying inventory and servicing across mixed mower fleets. - True All-Season Stability: Delivers reliable performance from cold starts to extreme heat with a -50°F pour point, outstanding high-temperature stability, virtually zero deposits, and exceptional resistance to shear. - High-Zinc Wear Protection: Elevated zinc anti-wear chemistry prevents gear scuffing and glazing, maintaining mower speed and ensuring flawless hydrostatic operation in tall grass, uneven terrain, and heavy loads. - Extended Service Life: Superior oxidation resistance, high film strength, and corrosion protection prevent metal-to-metal contact and extend fluid life up to 3× longer than OEM oils, making it ideal for high-hour commercial use and long storage intervals. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0C74Y4CK1 | | Best Sellers Rank | #2,391 in Automotive ( See Top 100 in Automotive ) #14 in Transmission Fluids | | Brand Name | Triax | | Compatible with Vehicle Type | Lawn Mower | | Container Type | Drum | | Customer Reviews | 4.8 4.8 out of 5 stars (1,033) | | Liquid Volume | 3.79 Liters | | Manufacturer | TRIAX Lubricants LLC | | Manufacturer Part Number | HYD20W50 | | UPC | 850023978073 | | Viscosity | 20W50 | ## Product Details - **Brand:** Triax - **Liquid Volume:** 3.79 Liters - **Package Information:** Drum - **Vehicle Service Type:** Lawn Mower - **Viscosity:** 20W50 ## Images ![Trans-Zero 20W-50 Full Synthetic Hydrostatic Transmission Oil | for Zero-Turn, Riding, and Stand-On Lawn Mowers | Unrivaled Year-Round Protection (1 Gallon) - Image 1](https://m.media-amazon.com/images/I/71jRGI45mbL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Saved my Toro TimeWaster Hydro *by D***N on January 3, 2026* This hydro trans fluid is the best!
