I used to use it on my JX85 push mower and GS30 WB mower, but dont anymore. Nothing wrong with it, just found it wasnt necessary.
Now its SD Polyurea or HD Moly. I have a gun for each one, use the HD Moly for pins on the BH and Loader, Polyurea everywhere else, including the Exmark.
The water resistant stuff is fine, but not necessary unless you are worried about water washing it out. Since I used to get caught in the rain, and also wash the mowers down all the time, thats why I used it. Turned out the regular stuff doesnt wash out from just a wash now and then, unless you are really trying.
My dealer recommended the combo I have now. Or rather their setup guy did, who has been there for about 20 years now, and fixes the stuff the regular techs cant seem to, lol.
According to my 2025 manual, SD Polyurea or HD Moly are preferred.
They do say that wet or high speed conditions may require special grease.
You certainly wont hurt anything using it if thats what you want to do.
