4-blade steel design (vs. 3-blade OEM) delivers smoother operation, better snow breakup, and more consistent discharge

Weighs nearly 7 pounds more than stock, adding rotational mass that helps maintain power through dense, icy snow

Tighter housing clearances increase snow velocity and throw distance for noticeably improved performance

Easy installation with included step-by-step instructions and video guide—most installs take under 1 hour

Only fits models with 6-bolt service plate gearboxes; not compatible with Spanish-made fully cast gearbox units

The Push Industries 118.605 All-Metal 4-Blade Impeller is a high-performance replacement for John Deere 47" and 54" front-mount snow blowers originally equipped with the plastic OEM impeller part AM138205. The stock plastic impeller is a known failure point, often cracking or breaking where the metal hub meets the plastic blades, which can lead to unexpected downtime in the middle of a storm. This upgraded impeller is built entirely from heavy-duty steel and features a 4-blade design instead of the OEM's 3-blade layout, offering more consistent snow discharge and smoother operation. It weighs nearly 7 pounds more than the original part, increasing rotational mass and acting like a flywheel to help the blower maintain power through hard-packed or icy snow without bogging down. Tighter clearances in the impeller housing further improve snow velocity and throw distance, making your machine far more effective. Installation is straightforward, with full instructions and a detailed video walkthrough included, and most users complete the process in under an hour. This impeller is only compatible with John Deere blowers that originally used the plastic AM138205 impeller and feature a gearbox with a flat service plate secured by six bolts. It is not compatible with blowers that use Spanish-made gearboxes with a fully cast, one-piece body and no service plate. By upgrading before the OEM impeller fails, you gain immediate performance improvements and avoid the risk of inconvenient mid-season breakdowns. This is the durability and reliability upgrade your snow blower was meant to have.
