The counter clockwise tach took getting used to when double clutching main box on the road
For snow blower, of the two reverse speeds, you have creeper slow (low range) and warp speed (high range).
When I ran a 78" on the 240, Low reverse was perfect, I used foot throttle and just held it to the floor, no worries over speeding a snow blower and it works better.
For deep snow you carry the blower a foot or more off the ground and just take the top off the snow 1st pass, if the RPMs fall off, clutch 1st stage and let the blower clear, good time to shift to forward (L4) and travel back to where you started, then drop blower all the way, or even just below 1st pass height, make second/third pass to clean the path. Once you have the width of the blower totally clear, you can take 1/2, 1/3, 1/4 width of the blower or whatever you can do without stopping/clutching.
I've had to chew through 4 foot drifts. Does take the toll on the clutch leg going back and forth.
