My stander mower has a dozen of these linkages for raising the deck, what lube should I use? this mower is stored outside (unfortunately).
Metal to metal - I am going with TSI321 cut down with alcohol, apply liberally to all the linkage joints for it wick in.
Once it dries, a shot of CorrosionX on any exposed metal and joints.
TSI is a a thin film lubricant. Thin film lubricants are good for very smooth surfaces, especially at lower loads and/or higher speeds (like casting ball bearings). It is going to be scraped off of normal surfaces fairly quickly.
Grease is the standard lubricant for sliding metal surface contact, unless inside of machinery that can keep the surfaces coated in circulating oil.
Why not grease?

Grease
Grease on/in those locations is surely going to attract an awful lot of dust and dirt. You best make sure you clean and relube those points frequently. ;)
Pull the bolts and grease them trying to avoid a greasy mess on the outside. The manufacturer should have but bushings on the pivot points.
Chances are they will out live the mower without any lubricate.
Although, if you want to keep them quiet and operating smoothly, then I would recommend finding some nylon washers to place between the metal hinge parts.
It looks like there's at least one nylon washer on the top bolt.
