My 790 and 300 loader are a bit weak on the breakout force so I looked at the difference between the 300 and 300x loaders. For breakout, it's just different bucket cylinders. Same closed length, same extended length, same ends but bigger bore diameter. Hmmm, go from essentially a 1.5" bore to just a fraction under a 2" bore and gain 33% breakout. My local JD parts guy was willing to work with me to confirm all that including that the two loaders have the same booms so the change should not over stress anything. "Great, I'm in. What do they cost?" He looked up the price. . . $800 each. That ain't happening for sure. Checked with another dealer and while better was still really high.
When I get a chance, I'll get the exact specs and see about other sources but it sure would be nice to have more breakout.
