I hate how far this thing throws snow compared to my old Gravely 44" blower. That thing was a beast. I took some pics of the impeller before I sold it so I could fab a new one based on that design.
First pic is the John Deere impeller. Very poor design to say the least.
Second is the Gravely impeller.
Third pic is the disk that I cut from a saw blade. I cut it on the mill with a rotary table down to 12" and cut the center hole larger to make sure it was centered.
Forth is the center hub with a hex cut in the end for the drive dog and sheer bolt.
Last is the hub on the disk with locator slots for the blades.
I need to get some steel for the blades and cut them out all the same, put a bend in them for the scoop and weld all together.
I hope I will be impressed with how it will work, if not at least it will be better than that plastic POS
