64 HP PTO Shaft with Integral Clutch — 1 3/8" x 6 both ends, 73"–105"

Closed is the shaft fully collapsed — its shortest. Open is fully extended — its longest. Your tractor and implement must sit inside that range at every point through the turn.

Cross to cross is measured between the centres of the two universal joints. Overall is the full length including the end yokes. Most machine specs quote cross to cross.

This shaft trims to length. Measure your machine at its shortest point — the shaft must not bottom out — then cut to suit. You can always take metal off; you cannot put it back.
