D-7 Hardnose and 7S Dozer Blade

Same coupling assembly as the 14A but the control linkage is completely different

Bob, Old Magnet,
If that blade will fit a 74A D6C and a D6C tilt cylinder without much modification, I would be interested.

Hi, Paso Bob.
Good find and catch. Suggestion - with your piece of country in mind, it might be worth swapping blades unless your current one also has those corner bits on it.

Just my 0.02.

I don't have all the dimensions to compare but these items are likely different when mounting to the D6C.
D7 17A blade is 10' - 3 1/2" wide, the D6C is 9' - 6 1/2" wide.
Mounting trunions are likely to be different diameter.
D6C lift cylinders have different blade attachment system then the 17A, also center to center spacing may be different even though they are both the same gauge.
Push arm length should be checked although I don't believe that is a problem.
Depending on whether you have an early or late tilt cylinder, mayor changes to the blade attachment may be required.
