20-, An improved compound transmission design is provided for reducing gear hopout, particularly during PTO operation. In this design, a spindle is rigidly secured to the input shaft, and a headset/fourth gear is rotatably mounted on a spindle by means of a full compliment needle bearing. A splitter gear is rotatably mounted on the input shaft and includes a sufficient diametral float with respect to the input shaft to minimize tipping of the gear while maintaining significant torque balance between countershafts. This configuration maintains concentricity in parallelism of the headset/fourth gear and splitter gear with respect to the synchronizer clutch in order to prevent gear hopout.

Why it's free to use
- Filed June 13, 1997 and granted September 16, 2003. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 13, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 13, 2019.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
