Were the lower hp tractors as harsh with the shifting due to the engine getting pulled down from the shift? Its been years since I've driven an 8 speed. There were two I remember distinctly, A 4230 and a 4430. The 4230 really didn't shift that hard, especially if you shifted into the higher gears at a lower throttle and then throttled up. The 4430 on the other hand was really crisp, like don't hold onto the shifter knob because the jolt would cause you to push it into another gear. Always thought it was the ratio jump was wide enough between 7 and 8 to cause the jerking? 1 Quote Link to comment Share on other sites More sharing options...
