</font><font color="blue" class="small">( My biggest concern for either Hyd or Gear is whether I'll be able to go through all steps in a single range. Because, it seems to me, that changing ranges for any model will require stopping the tractor.

The NH class III Boomers, TC35DA/40DA/45DA, all only have two gear ranges (high and low). Within each range, there are two hydro ranges (rabbit and turtle) that come from being able to change the ratio in the hydraulic motor in the hydrostatic transmission. That ratio is changed by two buttons operated by your thumb on the joystick and/or a fender mounted switch. The only requirement to stop and change ranges is when you go from low to high range, so on these model tractors you only have to stop once to go from the lowest gear to the highest gear. Since they have no clutch, all you have to do is stop, change the range selector, and go. /forums/images/graemlins/cool.gif
