Grasshopper Drive Fluid

[sdwiederin]

I have a Grasshopper zero-turn mower. In the manual it recommends Grasshopper #345050 fluid. That stuff is extremely expensive. Looking for a good alternative. Thanks.

What’s expensive?. I think any quality spec meeting alternative will be.

Appears to be an ISO68 lube.

It's hydrostat oil. Hydrostats almost never use something thinner than 30 grade or aw 68 and I imagine it'll be that.

This is the answer. I would use a quality ISO 68 lube and call it a day.

We used Mobil 1 15w-50 in those hydro units.
