I need to replace my hoses for the blade. They are the old clamp type that you just replace the hose using the existing clamps.  I found my notes from an old post that said to use <discounthydraulichose.com>    # R2-12-ABS.   The dash 12 is 3/4 inch which seems small but I dont know. Is 3/4 inch correct?  It is a little less than $4 a foot which seems very reasonable.             Any advice is appreciated.                             Grant.

3/4" is correct.

that is correct. just use your old clamp style ends. works great

I ordered 9 foot of hose last night. The old ones measure about 22 inches, so I bought a little extra to be sure of enough. for 4 of them. With shipping it was only $55 which is much cheaper than a couple of thin power steering hoses that I had made for my wheel tractor. They cost me $104 from Napa Auto. Thanks for verifying the size.
