The truck lives at the Zelienople airport (about 25 miles north of Pittsburgh) It moves dirt when needed in the summer. In the winter, it pushes snow on the general aviation ramp.
In the attached photo, the buildings are 315 feet long, and the distance between them is 75 feet for the two taxilanes toward the top, and 90 feet or so for the one on the bottom. The truck takes all snow from the ramp and the taxilanes (not from the taxiway running vertically on the right) and pushes it to the detention pond on the left. We used to stack snow there, but even through the fence is 15 feet down the hill, the piles became too big and started blocking the hangar entrance. Now we push to the edge of the pavement, and then use the blower the airport acquired to put the snow in to the detention pond.
No salt is allowed at the airport, so we push it once and then let the sun melt the rest. Even on an overcast day, the residual snow is typically gone in 4-5 hours. If the sun won't do it, the airport will broom the ramp area after they finish brooming the runway and taxiway. I think the rubber edge is OK here because the pusher weighs so much that there is good pressure on the edge and, more importantly, there is no hardpack. I have found that setting up the cutting edge 1/8" below the shoes is ideal for what I use it for. 1/4" and there is a lot more friction when pushing and it tends to turn the residual film into ice (I have to lock the differentials to keep pushing), 0" and it leaves too much.
The pictures of the truck a few years old, as we have not had any worthwhile snow this winter. The one from the snowblower is from last year, and was the first time the airport manager was using it, so he wasn't doing a great job.
At any rate, I have had very good experience with a deeper, rather than wider, pusher.
