im betcha i dont even use 4hi 90% of the time. I do mostly resi drives and i just drop plow as soon as I hit the driveway. Then i back up and drop plow and go forward again only using 3/4 of my plow at an angle, back up do it again.... etc......I figure as long as my wheels are driving over a cleared path, no need for it...I have also used 4hi a few times for making my intial pass when I let the snow accumulate almost 15 inches one time...after that it was 2hi using only 50% of my blade width
if i start to spin a bit, i reach down and move the transfer lever into 4 hi for a tad.... I don't think my current truck has ever been in 4lo.. no wait i lie.... it was once when i wanted to see it climb a hill with nuthing touching the throttle...... it was eerie to have that thing just crawl up with me only steering.....
If you have the Tow-Haul mode button on the shift lever it helps also in plowing ... Trans does not shift to quickly holds in gear a little longer !!!!
Like has been said, 4low sucks for backing up, because it is so slow. I use it on one parking lot I plow with a very steep hill, and sometimes one of my driveways as well. Keeps the tranny temps down, and it seems like a bad idea to me to hold the engine at 2500 rpms (barely moving) while pushing uphill with 4000 lbs of sand salt plus the weight of truck and plow and spreader, running 230 F in the tranny :yow!:. But then again, as long as there isn't a foot of snow down it's not needed. It is better for the transmission, but it costs you time.
