My 1 series has a very good calendar.
Never a sign of trouble from the rockshaft until today it started falling at a fairly significant clip (I didn't do the test exactly as in the tech manual because I do not have a 500lb +- 30 LB weight to attach, mine are either heavier or way lighter but even with just me on a trailer mover it falls fairly fast)
Of course I just got the cab installed last month and the warranty expired on the 5th of May
Oh well it shouldn't cause me too much grief as my position dependent three point usage (tillage mostly) is done until fall.
Going to have to start figuring out how to remove that nice TekTite cab (and finish up the review post I was working on)
EDIT: I was wrong my land plane is 493 lbs... And the Box blade is 490 some... can't beat that for 500lbs +-30... Thought the box blade was lighter and the plane heavier I guess I should check before writing such nonsense
I'll try the "official" test later but am sure it will fail
