Jim,
The bracket, with brush guard, mounted on the frame of the tractor is just over 90 pounds. Just the blade and the brackets weigh about 280 pounds plus some effective weight. I was able to bring my blade 9" closer than I have seen in other blades. I have fluid in the rear of my tires and I was grading my driveway and not slipping without front assist. The true test will be this winter and I have seen in brouchures that some show weights added to the rear. Now I need to get my fabricated pieces painted some time.
