had a bit of time to replace the ripper.
found some good sized bits of aluminium in the junk pile and come up with this, in picture it is fully extended down, in the up position it has about 50mm / 2 inches of ground clearance.
the paint is drying and should be dry for the official test run tommorow,
I want to make up a couple of covers for the cables on the blade tilt rams and then the dozer will be finnished.
