The 460/560 problems started earlier than stated here. During the Super M, MTA and 400 testing it was noted that higher bull pinion and inner axle bearing failure rates were being encountered. Nothing was done about it because the failure rates weren't that high. The sad part is that knowing this field testing was not done for the 560 when fitted with the more powerful 6 cylinder engine. John McCaffery even admitted this in 1958 that the 460/560 series had not been field tested before their introduction. McCaffery had spent all the R&D money on his bulldozers and none was available for field testing. That combined with weak senior project engineering management allowed this developing disaster to happen. When the senior engineer was fired he was replaced with a much more agressive individual whose idea was to do it right the first time. Harry bercher became president and his motto "build her stout" was adopted for the 706/806. The 706/806 was originally due to be released in late 1961 but the Hydra Matic transmission wouldn't shift properly. It was abandoned and a straight spur gear and TA unit was substituted. This delayed the introduction to late 1962. Then Harry Bercher insisted on an additional full year of testing to make sure the tractor would be reliable under all conditions. This delayed the introduction until mid 1963 and ensured that the tractor would be very reliable..
