I ask because I often have to shovel a short hill on an older gravel driveway that has two distinct tracks that the wheels follow.

I'm not concerned about going down the hill but to get up the hill shoveling is often required. I've been shoveling both the left and right tracks...but I'm now wondering if I might be doing too much work because only the left or right wheel is actually doing the pulling.

The more I think about it the more I'm thinking both wheels drive equally, but I'm asking anyway.

If perhaps one side does actually do the most pulling, which one is it?

Should I shovel under the passenger side or the driver side? Or both?

Thanks.
