This is a hard to find auger rakes set from a Bolens 824 snowblower. Both sides are in good used condition and should fit others models such as the 524, 624, and 724. These measure 16″ in diameter and have a center pipe length of 9.5″. These seem to be interchangeable with 1725116 and 1725117, and are identical except for the angled clip at the outside end of both augers. Please ask if you have any questions or need some measurements. If you only need one side, just send an offer. I have many more parts for these machines, let me know what you need!
