Since obtaining my 1440 I believe I would like to change out the snowblower attachment. Little confusing and since I do not have close access to a dealer - thought I would toss out the question of "which snowblower attachment would you be considering" for replacement of my single stage old model (mostly because it is heavy and cumbersome) . I have looked some at the 451 and 19A40024100 however do not know what will actually fit. Anyone that has information, doing it, or suggestions certainly would be helpful. Thoughts welcome!
