Hi heres a couple of pics of my homemade grader/dozer .
The 2 blades see saw on a pivot under the front wheels
the front blade works a treat for spreading gravel and the middle blade levels like a charm. The middle blade is just a piece of 4x2 chanel bolted on with 2 steel straps so it can be angled if required.I used the deck lift cylinder to move it up and down . It doesnt look pretty but i had to knock it up in a hurry to move 12 tons of gravel
