Service Bulletin: 521725 PTO Shaft
Part #521725, Intermediate Z50 shaft used on Pro-flex 120/TD65/TD65-2
For a period between 2003 and 2006, this PTO shaft was changed to one with a new shield. The shielding
seen in "Diagram 1A" was used before this, and was changed to shielding seen in "Diagram 2B" for this
period of time. See diagrams below on page.
If your Progressive Mower has an intermediate shaft with shielding as seen in "Diagram 2B", the parts
breakdown listing for the inner yoke found in your machine parts book is incorrect. Part #521721 (Yoke -
Outer Tube) must be changed to Part #521721.50 (Yoke - Inner Tube). The size of hole for mounting yoke
on the shaft is different in each application.
