John Deere Hy-Gard Transmission Oil | 1 Gallon | TY22000

Is the Wrong Oil Killing Your Hydrostatic Transmission?

Your zero-turn jerks when turning, creeps in neutral, or whines under load. The hydraulic fluid is dark, burnt, or low. Generic oil doesn’t meet John Deere’s exact viscosity and additive specs — and every hour you run the wrong fluid accelerates seal wear, spool valve damage, and eventual transmission failure that costs thousands to replace.

The Only Oil John Deere Recommends

John Deere Hy-Gard (TY22000) is the factory-specified transmission and hydraulic oil for every John Deere zero-turn mower. Engineered for the exact operating temperatures, pressures, and seal materials in your hydrostatic drive system. One gallon handles a complete fluid change on most residential zero-turns.

Why Hy-Gard Outperforms Generic Hydraulic Oil

• OEM Formula TY22000 — The exact fluid John Deere engineers designed your transmission around
• Anti-Wear Additives — Protects pump gears, spool valves, and seals from premature wear
• Thermal Stability — Maintains viscosity from cold starts to peak summer temperatures
• Foam Resistance — Prevents aeration that causes jerky operation and cavitation damage
• 1-Gallon Jug — Enough for a complete fluid change plus top-offs between services
