4040 Rear PTO Spline Size

Recommended Posts

Guest
Does anyone know the size of the rear PTO spline size on a Powermax? Also, know of any adapters available to match up to 1-3/8" 6 spline equipment? Finally, some suggestions on adding 2 additional hydraulic ports with control for a front end loader. Thanks Phil

Phil, The PTO is a 1" involute spline with 15 internal teeth. It rotates at 2000 RPM at rated engine speed. If using a loader, I would not recommend using the tractor hydraulics, but rather a separate hydraulic system driven by the front PTO. Paul

Paul: What is an "involute" spline? Hey--did you say "spline?" As great as these tractors are, (and they are!), I didn't think Simplicity knew that word--I haven't seen a spline on either of ours yet. J/k. Peter

Peter, An involute spline tooth is much like an involute gear tooth. The side of the tooth has a radius of curvature such that when it meshes with other teeth on the driven component the contact point creates a "pressure angle" measured from tangent with the pitch circles of the two gears. Involute merely refers to the design of the sides of the teeth on the splined shaft.
