Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

I used to own an old Gravely walk-behind that I used for plowing snow and mowing (had a rotary as well as sicklebar). I sometimes regret selling it. Anyway, once when I was using the sicklebar a sicklebar part came off. I bought a new one. The old one reappeared last year while I was breaking new ground with the tiller. It's rusty and pitted, but still useable and I could probably sell it on eBay. I have a sandblaster which would be ideal, but hauling that out this time of year would be a pain. Are there any products that are good for removing rust that I could try?
