Industrial 21-spline female to 1-3/8-inch male PTO splined extender adapter, rated for 125 HP, connects a 21-spline female PTO to a 1-3/8-inch male spline in extended PTO assemblies. The design preserves spline engagement between the two mating ends while adding the necessary reach for PTO drive-line configurations. On one end it presents a 21-spline female PTO interface, and on the opposite end it provides a 1-3/8-inch male spline output. The 125 HP rating defines the maximum power that can be transmitted through the extension in typical industrial applications.
