Is the gearbox supposed to use a 90 Weight oil or grease? I took the plug out expecting to be a 90 Weight oil and it looks lie it is grease in there ? To my confusion I looked at a manual for the Toro Powershift and this is what it stated..
Lubrication is supplied by an SAE 90 weight extreme
pressure (EP) gear oil with an API rating of GL-5 or GL-6.
This is necessary because of the temperatures and
pressures provided by a worm helical gear arrange-
ment. Do not use Lubriplate(R) Mag 1 grease in the auger gear box
