I bought a grass gator heavy duty bump and feed head for a swap on a cub cadet I had in the shop. It wouldn't fit it so I kept it since to send it back to amazon.com would be more than I paid. I ended up trying it out on my old RedMax. It's a great buy @ 13$ ! Actually it's made in USA and turned out to be alot cheaper than a import oem replacement. Runs .105 line wonderfully.
