Oil in the roto hoe?
 

I have a Cub 127 and use the roto hoe attachment. A while back I saw a manual for the roto hoe and thought it said there is an oil bath for the chain. So I went to look and can't see where to fill the oil. Does anybody have a link to the manual or know if there is supposed to be oil inside the case and where the fill is?

I am "assuming" you have the IH built tiller (Roto Hoe). With that in mind, here is a link to the Owner's Manual...... Tiller

Grease.
When I overhauled and rebuilt mine several years back I packed the gear case with wheel bearing grease.
Works fine ever since.
Installed all new chains and bearings.

I filled mine with JD Cornhead Grease, five tubes, I think.

I also welded a pipe bung on top to check and replenish the lube. On a hot day of tilling it does weep some lube.

Thanks!
 

That is great. Thanks for the info. That helps a lot.
