There is some discussion about the fan hub lubrication in the cub section of this forum, but little to no information is posted regarding this in the lubrication guide for the numbered series tractors.
It "looks" like the same fan and hub is used on the numbered series, but I don't see a place to lubricate the bearings.
Is this required? If required, how is this accomplished? I don't see a place to grease or an oil cup.
