Brush guard for non trellised rows

[nayab]

Is there some kind of contraption for pushing aside brush so that the tires doesn't trample it.
I have a blueberry farm and often have to mow between the rows. When the fruit forms the vines/branches become heavy tend to bend down into the rows. Then when I try to mow, my tractor tires may grab and trample on these branches. I was wondering if there's some kind of extended bumper guard or shield that will instead temporarily push the branches aside out of the way until the tractor passes?

I have the same issue with tilling my raspberry rows. I eventually came to the conclusion that pruning the plants to remove the low hanging branches early in the season is the most workable solution.
