I have an International 350 Disc Harrow and am having trouble greasing it. 2 of the zerk fittings will not take grease. Grease just comes out between the xerk and the grease gun fitting, The rest work fine. Tried to replace the zerks but they it will not come out. What am I doing wrong?

Problem may be the fitting on the end of you grease gun. I have attached my grease gun fitting to a grease zerk, that did not take ease and levered the gun with a good bit of force. The gun fitting did not leak or come off the zerk. Being on a disk another problem may be a worn zerk fitting from the dirt wearing the fitting ball end down, causing a bad fit. I would think that's your problem. I have a grease gun fitting with a tapered point, you put right on the ball. (A tapered end, not a needle point fitting) I have seen grease zerk fittings that are pressed in, not threaded. I don't know how you get these out. Stan

Some fittings are pressed in some are threaded in. If you have a hex on the fitting it would be threaded in. There are several thread patterns so be sure to get the correct replacements.
As for getting the old ones out I would spray them with penetrating oil and then tap or pound on the end of the fitting maybe 200 times each. Hit them as hard as you dare. Then come back tomorrow and spray them again then try turning them out. If they still won't turn repeat that procedure until they do come out. Do not use WD-40, use actual penetrating oil.

It's a disc that spends its time in the dust and dirt. God knows how/if the previous owner ever greased it. There is probably dirt and dried up old grease packed in the channel behind the zerk.
That's assuming the zerk is aligned to the grease hole in the bearing. That's assuming the bearings are even greaseable.
