 This explanation is a bit long, so bear with me. The S/N tag on my 450 LP is 25xxxC CR. "C" denotes LP gas, and the "R" denotes Torque Amplifier Attachment (With provision for Transmission Driven Power Take-Off Attachment). Problem with this is that my tractor has an Independent PTO unit and it is a factory-delete T/A. Suffix "P" more accurately reflects the current situation of my tractor: Independent Power Take-Off Drive Attachment (For use without Torque Amplifier Attachment). I do not believe any modifications were ever done to either the (lack of) T/A or the IPTO. See picture. The left coupler is the modified one and is not shown in my parts book. The left shaft is the one that takes the place of the T/A unit to transmit power from the engine to the IPTO unit. Is it possible the tag was not accurately stamped at the factory? See next response for picture of the coupler. Has anyone come across this before? Maybe I have the only 450LP factory-delete T/A with IPTO in existence? Yeah, didn't think so.
