I'm with you. I've NEVER heard of a hydro pump that runs on anything heavier than a 20w-50 motor oil! I think the older IH cubs had sauer-sunstrand/danforth pumps, the MTD cubs have peerless or hydro-gear as far as I know. Only way I know of to post an email is either cut/paste it into your post, or post it as a .pdf as you would a picture. Hopefully some other goo-roo's will chime in!
