I have 3-HI loader and a 3-WI loader that I could sell you.
The 3-HI is probably better from an HG (see pic enclosed).
The 3-WI really needs an industrial model (like an OC3), I think.
I am in Upstate NY (top of I-81), and the whole set-up will cost you about $600.
It is quite easy to modify the back of a blade to fit the loader arms for Winter. ware sold a removable blade that fit the 3-HI.

If you really want a push-blade ONLY, I have one but the blade will need a bit of TLC as it is a bit rusted out in a line above the reinforced cutter blade. But everything works fine. $600 for whole set-up. I have both the Anderson 'Imp' set-up (over the hood) and a single cylinder at the front type.
