1 Gallon - Hustler Hydrostatic Transmission Oil (606953)

Product Specifications:

Genuine OEM Hustler Turf Fluid | Viscosity: SAE 20W-50 | Volume: 1 Gallon (128 fl oz) | Zinc-Based Anti-Wear Additive Chemistry | Up to 750-Hour Extended Service Protection

This genuine factory Hustler 1-gallon full synthetic hydrostatic transmission oil is specifically formulated to protect internal wheel motors and hydraulic pumps on Hustler commercial and residential zero-turn mowers. Engineered with extreme-pressure zinc chemistry, it resists severe viscosity loss from shear and extreme operating temperatures while preventing sludge, varnish, and carbon accumulation.

Hardware & Maintenance/Inspection Notice:

• Always replace your hydraulic filter(s) whenever performing a transmission fluid flush to protect delicate hydrostatic charge pumps from abrasive particles.
• Purge air from the hydraulic circuit according to factory guidelines before operating under load to prevent pump cavitation and erratic tracking.
• Need matching OEM hydraulic filters, fluid change kits, or 1-quart bottles? Check our "You May Also Like..." section below for matched genuine service components.

Serial/VIN Verification Reminder: Always confirm exact transmission model specifications and fluid capacity using your machine's 6-digit product ID decal located on the frame ID label prior to ordering.
