Has anyone ever cut a access port thru the floorboard for the purpose of greasing the elusive front drive line zerk?
The best way to service a 2210 is to trade it in! I went through the destroyed driveshaft. There is a panel on the side of the steering column that may allow you to get at it. Honestly you might have better luck with the seat pan off. It's a bit of a bear because you have to remove the ROPS and other stuff but worth it in the end. It's just a real PIA to get at so you need to decide how much it is worth to you to do an depth procedure for a routine service.
How many hours are on your machine?I did spring service on tractor yesterday, had the tractor up on 4 stands, went underneath and used the grease gun attachment with the cupped end. With one hand pushed tip hard against zerk, with other hit the trigger in Milwaukee m12 grease gun.
Of course some grease went all over, but I swear I saw some come out of the knuckle. Happy with that, but ya just never get the “i got it” confidence with that zerk
