Bale Throwers - New Holland 70 vs 72

Hey there all!

 

Just starting a philosophical thread.  I've got a New Holland model 70 bale thrower (hydraulic drive - bought it used, so unsure of the year, but still had almost all of its paint when I got it.  Actually have it on a Massey 124 baler now, but that's a different story.)

 

I know (think?) the 70 was replaced by the 72 - but have always wondered "why".  The 70 seems pretty beefy and resilient, plus I like the vertical tension rods that allow broken bales to exit without jamming. 

 

Looks like most/all new New Holland balers come with 72's these days, so just didn't know if it's a full-on replacement, or if the 70 is somehow still an "economy model".  (Also why oh why they went back to the tension rods that are perpendicular to the thrower - at least in my experience with old Massey throwers set up similarly, just creates a great place for broken bales to jam up...)

 

Anyway, just curious for y'all's experience.  Thanks!!
