I am curious and have a question and there is probably a good answer which maybe someone here can answer. I have the 300CX FEL on my 990. I know that is what JD is presently distributing. It has cast iron masts which are made in China. I am assuming the other FEL's that are on the 102x series, the 2x20 series and 4x20 series have the same cast iron masts. I don't know if I am right or not but the JD FEL's which were sold prior to the present series appear to have been all steel. Am I correct in that? If so why did JD move to the cast iron (I am guessing I know why getting them from China)? Is there something better about having a cast iron mast instead of a steel mast? It just seems to me that all steel would be better and that cast iron would be more brittle but again I don't have any knowledge here. Just some experience where I have seen Cast Iron break where steel does not seem to break so easily.

Yes if it is ductile cast iron then it sounds like pretty good stuff. I found this on the ductile iron Ductile iron - Wikipedia, the free encyclopedia and this http://www.metal-technologies.com/DuctileIron.aspx and this http://www.ductile.org/dimg/orangechart.html and this http://www.ductile.org/didata/default.htm There are many other links if you do a search on ductile iron. It would be nice to know if these masts are really ductile cast iron.

I edited this to add one more site which talks about Austempered Ductile Iron (ADI) which really sounds like good stuff. You can find it here http://www.specialtycastings.com/ductile_iron.html

Again it would be nice to know whether these masts are made out of one of these types of ductile iron.

The H120 (for 102X series) are made of "Nodular Cast Iron". A properly designed cast iron part can be made in one piece with equivilent strength and with far less machining than a steel one. I'll bet nobody will break a cast mast before any of the other loader components.

H120 Loader Loading and Digging Utility Tractor Attachments JohnDeere.com

"The loader mast is made from nodular cast iron, which enables the unique shape.

The unique shape enables metal to be placed in the areas where it is needed to provide strength and durability.

The mast latches to the mounting frame on the H120 Loader, and the latch can be opened when down pressure is applied to the loader to allow the mast to rotate forward and be removed during the parking or detaching process."

The older 210, 410, 420, 430, and 460 loader had a cast part as well-but it was just the "claw" at the lower part of the mast that engage the square tube mounts on the tractor. Even the QA shoes (the parts the bucket hangs on) where built from 1/4" plate steel.

Now the masts, loader mounts, and QA shoes are all cast in China...I think we know why.

Kenny do you know if they are ductile iron at all?

I have no clue Rob. It's welded so I guess it's not "cast iron" per say.
