brush guard

Finished up clearing some land and the rains have started. Tore up the grapple hydraulic hoses and got way too close to damaging the grill/hood several times. I have had the materials sitting around for a year to make a guard and finally got to it:

I want to put this on my dump truck, but cannot find one anywhere. Easy to find for small trucks, but can’t find for big ones.

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...

Are there any aftermaths brush guards that fit a work master 70?
