Medium-lift mower blade 16 9/16

This Stens 305-771 medium-lift blade measures 16 9/16 inches long with a 3/4-inch centre hole, 2 1/2-inch width and 0.203-inch thickness. It replaces Ariens part numbers 03123700, 03123751, 03123759 and 21085400 plus Woods 03123751. The blade fits 48-inch decks that require three blades per deck.

Installation fit and common issues

Installation is a direct bolt-on when the centre hole, length and width match the original equipment specifications. Problems usually arise if the deck spindle pattern or blade offset differs from the listed OEM numbers, so verify the part numbers before fitting. Torque the mounting bolt to the mower manufacturer's specification to prevent loosening in use.

Suitable decks and mismatched needs

This blade suits owners of Ariens or Woods 48-inch decks that call for the exact part numbers above and a medium-lift cutting profile. Buyers with decks of a different width, a different centre-hole diameter or a high-lift or mulching requirement should look at other blade designs.

Questions about this item

How can I confirm the Stens 305-771 blade is installed correctly on my 48-inch deck?

After fitting the three required blades, check that each centre hole seats fully on the spindle, the 16 9/16-inch length matches the deck specification, and the cutting edges rotate freely without contacting the housing.

What comes in the package and do I need extra hardware for installation?

The box contains one Stens 305-771 medium-lift blade with a 3/4-inch centre hole; mounting bolts and washers are not included and must be sourced separately if the originals are worn.

Which Stens blade version should I choose to replace Ariens 03123700 on a 48-inch deck?

Select the Stens 305-771 medium-lift blade — it directly replaces Ariens 03123700, 03123751 and 03123759, and three units are required for a 48-inch cutting width.
