Good oil

Seems to be great and cheaper then through John Deere

Affortable and works good. Recommended for your zero turn hydrostatic pump.

Works great in my Craftsman z8400 zero turn HydroGear motors. I would have given it 5 stars, but I needed 5 qts total. This is only 4 qts, and Triax doesn't sell this by the quart. So I had to buy another single quart of a different brand.

I used this on my Ferrix IXS 800 w/ Hyrdro Gear zt3400 hydros, I only had 50 hours on the mower, but the hydros where squelilng so I figured it would be worth changing out the hyrdro fluid. First off, it take almost 5 quarts, so that is the only downside, I wish it came in a 5 quart container or multi-pack. , thats the only negative. After I performed the service, the hydros worked better than when the mower was brand new. It was reactive, more power, it turned like it never had before, and handled hills that it couldn't prior. I'm not sure if there was a problem when it came from the dealer, but I never really knew it was under performing until I did this service. according to the label it doesnt need changed for 1000 hours, but I'll keep an eye on the fluid, if it gets dark or milky I'll change it out again. Service took me about 2 hours total, I'm probably slow.

Perfect for my Scag 61 inch mower
