Chris,
Are you going to mount that blade to the bucket or directly to the loader arms? My 6.5' Meyer project is nearly done and it will mount to the Koyker loader arms.
The Meyer original A-Frame is made of tubing and one angle iron. We cut off the chain, hose loops, and the two quick mount lugs, leaving only the bare A-Frame. The moldboard and trip frame are temporarily disconnected. We are boxing in the upper and lower part of the A-frame and making the box as close as possible to the moldboard in order to bring minimize the distance from the loader arms to moldboard.
Each end of the box has two welded vertical brackets that will pick up the four pin holes/pins previously occupied by the bucket. Can send you photos.
The angling valving, with help from Rob, is done along with another valve to the new rear remotes for the log splitter.
