Hi, my name is***** will be assisting you.

I would not put any lubricant on those parts at all. If you do it will only attract dust and dirt that much worse and cause it to stick and not work properly.

The only place that you would need any kind of lubricant is inside the transmission casing itself.

Expert:  JohnF2015 replied 8 months ago.

The oil or grease if used will only create more problems for you later on once you have used the machine a few times due to the attraction of dust and grass that will be captured by the oil and grease residue. Adding oil, grease or any kind of lithium based lubricant is not good for those parts, you are better off to assemble them dry with no lubricant or if you feel better about putting something on them you could use a dry graphite lubricant that way it doesn't leave a sticky residue to collect dust and debri.

Thank you it has been a pleasure to assist you.

The dry graphite lubricant sounds good but will it get sticky if gets wet from say wet grass or washing periodically?

Not usually, it tends to repel water due to the chemical compound of it but if it gets oil to it then it will soak up the oil and become a paste which would then be bad for that drive system.
