Perfect fit, very well made
My Scotts/John Deere mower is 10-15 years old and the nubs on the old adapter just wore right off, causing the blade to unwind from the shaft. This adapter is the perfect solution, as it is very rugged, fits perfectly and has the full nub to hold the blade in place. I would definitely recommend this adapter if your nubs are worn and your blade keeps unwinding from the shaft. Also, make sure to get new bolt and washer (like $1 each) and torque to 45-50 ft-lb.

My JD mower is close to 20 yrs old. The nubs on original blade adapter wore down, causing blade slippage and terrible noise. The new adapter fit perfect and so far works great. Make sure to choose correct shaft size, as there are 2 difference diameters. Service was excellent, shipping very timely. I would buy again from Green Part Store.
