Oil for Sicma rototiller

[theSeb]

Hello from England.

I have a Sicma rototiller (or rotavator as we call them) and I have lost the manual for it. Before I give the dealer a call, what grade/viscosity oil should I be putting into it?

For reference, I think it's the same thing as this

Phoenix T15-GE Series Heavy Duty 80" 3 Point Hitch, Tractor PTO Driven Rotary Tiller from Sigma

Gear oil of 80 to 90 weight. Don't use transmission fluid, motor oil or thick grease. Needs to be gear oil used in gear boxes on agriculture equipment. You can use heavier weight but just about any "gear" oil will do fine. That is a nice heavy-duty tiller by the way.

Thanks for the advice. It's served me well so far working quite heavy clay.
