G'day Chad

It's amazing how long these old mowers will run for ,made to repair instead of replacing.

There is an owners manual and some model history here thanks to Jack, it mentions lubricating the mower bearings under servicing.
The manual mentions 5 grease nipples, on some mowers they have spring loaded caps that you lift up and squirt oil into.
