Blade Adapter 997027001

This OEM blade adapter is made of high-quality metal and is compatible with various models of lawnmowers and lawn tractors. It connects the lawnmower blade to the crankshaft, allowing the blade to rotate freely and cut grass effectively. This adapter has one keyway/tab, a full-circle, and half-circle, on each side of it to lock the blade to the crankshaft. Failing to replace this adapter could result in poor cutting performance, and increased wear on other components like the crankshaft, and could pose a serious safety threat. To replace this adapter, you will need to prop/wedge your lawnmower up on some wood to access the cutting deck. You will also need a wrench to loosen and remove the bolt securing the blade and adapter to the crankshaft. Replacing this adapter is as simple as tapping it lightly with a hammer to jostle and carefully remove it, and then install the new one.
