I ran into something that I hadn't notice before on my 54" deck on the Z710A...The grease zerks on the deck spindles are of a "odd size". I needed to make the regular schedule grease job on the three spindles and when I used one of my many grease guns, the tip was too large for the zerk fitting. Before, I used the pump action grease gun, but I had ran out of grease on that gun and used one of my older style guns.
On my '99 JD 345 the zerks on the deck spindle are of different size...larger. However, those spindles on that deck are replacements from the factory ones. I have a older John Deere (green and yellow color) handle lever type that I have used in the past greasing on the 345. I guess I'll move the grease tip from the pump type that has the smaller tip to the John Deere gun. That way I will know what gun to used in the future.
Also, these grease zerks are not the removeable type. They are made into the top of the spindle somehow. Odd that whoever makes these spindles on John Deere would use a small size zerk fitting.
