Picking it up is manual. Almost everything on it is the same as what is listed in the tractor operating manual as being the correct factory optional snow thrower for this particular tractor except size. This is a 40" and the manual lists a 36". I'm thinking 4" isn't going to be a "make or break". The manual also shows the correct one being mounted off frame pickup points where I have this one mounted completely off the mower deck hardware, hence my questions.
