I'm sure the info I seek is on here somewhere but I cant find it with the site search engine. So what are all you Ariens guys using in your rotary mower gearboxes(831012) and also the Sno-Thro(831010) worm drive for lubricant? I have the original manuals and the lube that is being specified for each is proving to be either quite elusive or quite expensive. I do have some Ariens Semi-Fluid '00' grease Extreme Pressure that came with my GT16 that the previous owner had. Not sure if its compatible. Sorry in advance if this topic has been beat to death before. Your input is appreciated.
