I have a 5' rear blade for my bx1860 that works great for most snowfalls. It is about 3" wider on each side than the tractor when it is angled to drag the snow off the driveway. But, when the snow gets over 8-10 inches or so it would be nice to have about a 6" extension on one side so I don't need to drive with my tires in the snowbank. It doesn't need to touch the ground, just push the snow a little further over. I would like to be able to move it to the opposite side of the blade at times, if possible. Oh, I always use it driving forward, not backward. Any ideas on how to do this? Thanks is advance!
