On the zerk fittings......I have a FNH 1715 and the zerks are not metric or SAE....they are some kinda European thread. Nothing else fits. This is on the tractor only....They are only $4 each...ha ha. Hadda go to the dealer to get them. Think they are 9.6mm in dia on the thread, so a common 10mm won't fit.
Good luck. Pete in MS
