Check, my blade is quite a bit taller than yours, it looks to be off something else judging for the brackets that had to be removed to make room for the current ones. The blade attaches to the ends of the push bars with a pin. The threaded style tilt adjuster mounts on the right side top of the blade then angles down fairly sharply to about where the bracket with the hole is on yours.
O-R-H, mine has the cylinders mounted right up next to the radiator like Check's.
A farmer friend wants some trees cleared from around an old house so the fire dept. can burn it. He has a construction equipment style trailer and says 11K is okay, dunno about nearly 20.
