VEVOR PTO Shaft, 1-3/8” 6 Spline Tractor and Implement Ends PTO Driveline Shaft, Series 4 Tractor PTO Shaft, 43”-59” Brush Hog PTO Shaft with Slip Clutch Black, for Finish Mower, Rotary Cutter

I am having a hard time confirming the expanded workable length. By the answer, it appears it would be approximately 52 inches. I am interested if the expanded length is 59”. Can someone confit, Also, can you confirm the diameter of the slip clutch.

Q: 1) Are the Compressed Length (43") and the Extended Length (59") the working range the PTO shaft can be used within to operate the tractor implement or are they the extreme limits between which the shaft sections will bind (compressed) and pull apart (extended)? If these are not the working lengths please confirm the minimum and maximum safe use lengths. So if I understand your previous answer, the maximum workable length of this shaft is a little over 63”, is that correct?

What diamter is the slip clutch ?

can the vevor shaft that is 43 to 59 be shortened to 28 inches

If these are not the working lengths please confirm the minimum and maximum safe use lengths. 2) What are the reference points for these lengths, are they the very tips of the female spline receivers or the distance between u-joints?
