PTO Adapter / Extender — 1-3/8" 21-Spline QD Female to 1-3/8" 6-Spline Male

The Braber 501PA is a combination PTO adapter and extender — it both converts spline count and adds shaft length, for connecting mismatched or farther-set implements. It adapts a 1-3/8" 21-spline quick-disconnect female end to a 1-3/8" 6-spline male end, and adds 4-1/4" of reach in the process. A quick-disconnect (QD) collar makes for fast, tool-free hookup, on heavy-duty steel construction.

Convert and Extend in One Part

Sometimes a hookup has two problems at once: the splines don't match and the implement sits too far back to reach. The 501PA solves both. On one end it accepts a 1-3/8" 21-spline shaft through a quick-disconnect collar; on the other it presents a 1-3/8" 6-spline male output — bridging the spline-count mismatch — while adding 4-1/4" of shaft length to close the distance. The QD collar snaps on and off by hand with no tools, and the heavy-duty steel build stands up to the torque of real power transfer.
