Saw a gritter/spreader truck earlier with a plow attached to the front in what I thought was the down position. However when it went past I could see the rubber strip at the bottom wasn’t even touching the snow.
OK the snow may only have been two or three inches deep but what are the parameters for using these things?? There was a rotating brush half way down the vehicle also but it didn’t seem to be doing much either…
d4c24a:
about a 40 mm gap between the rubber and the road surface ,if it was touching the road it would not last long
40mm, about an inch n a half?
That seems like a fair bit of ice and snow left behind, to me.
It’s also a bit confusing. All the ploughs I remember seeing have a pair of little dolly wheels just behind the blade. They are presumably adjustable to keep the blade at a set height above the road surface. What would be wrong with setting them so the blades rubber is 4mm above the road? Above the road surface is above the road surface. OK so there would be a bit more wear, but its a strip of rubber put there to wear and to be a flexible edge that won’t damage the road, surely that’s its purpose.
With the current road conditions I can imagine the plough’s are ploughing up more than just ice and snow !!! Flexible or not eh ■■ You could lose a small car in some of those holes on the A43 for example !!!
The plough clears the X amount of snow and the grit melts the last couple of inches? Surely it can’t be set too low to otherwise there’s a chance it could catch.

That’s about as good as it gets during a real winter.I don’t remember plough wheels being adjusted but it’s obvious that what’s left behind is enough for the tyre tread depth to cope with and reach the road surface.
15 - 25 mm is by the book , most of my route involved country lanes ,that are far from smooth ,all that happens is the rubber wears all uneven ,mostly the snow and ice build up in the “gap” and act as a rubber
believe me it does not take long for it to wear out ,the day driver lost the rubber from around one jockey wheel ,but carried on thinking it was ok as the blade is in float while in use , but in less than 20 miles the rubber was gone on that side
