Also get yourself a spray can of "dry Lithium Chassis grease.
Lubricate all of those items ( and everything else where 2 metal parts move over each other.
Keep the deck clean , blow it down with an air duster after use and regularly lube .
IT is very dusty under there and depending upon the nature of your dirt ( sandy grinds & clay lubes ) those parts can wear to a critical point in a couple of seasons.
FWIW I use a full can of grease for every 2 to 3 mowers I service .
Also pay attention to the steering gear and the bush at the bottom where the steering shaft passes through the floor .
When you get the manual you will see it is supposed to be oiled every use ( no one does ) .
everywhere that the manual says to oil you squirt with the spray grease
