Steering Sector Grease

[brewsky]

This looks pretty exposed to dirt, but I can find no mention of greasing it in the manual?

Obviously, the factory didn't think it needed any!

Bel Ray synthetic grease, white lithium spray grease, motor oil, silicone spray, motorcycle wax type chain lube, or nothing?

The bush directly above it needs regular lubing.
Silicone if it is plastic, light oil if it is metal.
The fan gear & pinion get a lot of dust so a dry lubricant is the go.
Lithium spray grease works well but only when applied AFTER you have finished mwing & blown down the mower so it does not become a medium for holding abrasive dust.
