Back in 1950 Buick made a car named the Dynaflow. It had high gear and a torque converter. When you wanted to move you step on the gas. You could hear the engine race and slowly the car started rolling as the torque converter started converting torque. If you kept the gas on long enough it would hook up and you would be rolling quietly and smoothly. Your tractor doesn't have that. It has gears and a clutch. To take off in high gear with a machine that weighs probably 7000 lbs is a big job. You should be able to shift up from a lower gear once you get the tractor rolling at a low engine rpm, then you can advance the rpm's in the high gear. Most tranny's are semi synchronized which will allow you to do that, but rpm's need to be low. Also road gear (high) is a long way (ratio) from 7th or 6th so you can do a lot of starting off in the lower gear with ease. The diesel has really good low end torque but starting in high gear is tough. Only thing about shuttle shift is that they put the gears where you can easily go from forward to reverse; nothing special about the setup other than the shift pattern. Since backhoe's do a lot of fore and aft stuff in covering holes they dig and all, mfgr's figured it'd go smoother if they located the fore and aft gears right across from each other. Had a '74 IH 464 42hp with it. Mark
