At the sickle bar end of the pitman on a COCKSHUTT BUILT #315, (should be the same as the #415) The Latch assy. is GY-2906. The pitman assy. complete is GY-2968. After Oliver took over Cockshutt Farm Equipment in 1962, Oliver changed the mower model number from #315 to #415. The #415 was offered in OLIVER name and green & white paint in the USA and COCKSHUTT name and red & white paint in Canada. Oliver re-assigned new part numbers on all the parts. AGCO should be able to cross over the COCKSHUTT numbers that I listed above.I have not yet gone out to get the stick dimensions. Hope to get it done today................Phil 215-256-8651.
