<font color="blue"> The reason I can't set and forget is, snow tends to pile up in different depths in different places, I found that with the hydrostat, I would have to vary my ground speed a LOT to keep the engine happily revving along. I could be zooming along, then hit a big drift or something, and the engine would bog.... it's motly a convienence thing I guess... The only place I could use cruise is on the flats, of which I have precious little. </font>
This is intruiging. Are you wanting the PTO speed indicators so that you can constantly ride the throttle instead of the hydro pedal? Or just wanting a visual indication of PTO speed so that you can adjust your ground speed?
I don't have a series II Boomer but my experience with a TC40D blowing snow indicates that it is easier to set the RPMs at the high end of the 540 indicator and use the hydro pedal to vary the ground speed. There is not much "headroom" past the 540 speed on the throttle to make a whole lot of difference once heavier/deeper snow is attacked. I usually vary the ground speed to keep the engine load consistent, since it is so convenient with the hydro, judging the engine speed by sound and by how far the snow is being thrown. That thrown snow is a pretty good indicator, as long as its not being thrown back in your face by a sudden change in wind direction /forums/images/graemlins/shocked.gif.
It seems that reaching forward to goose the throttle while twisting and watching backwards would be more awkward than using a foot to vary the speed. Why would varying the throttle speed be easier than varying ground speed? Is the rocker pedal difficult to use on the series II?
