My son sent me a picture of a restored John Deere 520 with a steel can attached immediately in front of the govenor case on the flywheel side. Probably was made from some moderately thick steel tubing. Has a bottom welded to it, with holes for drainage. Tractor has been passed down in the family, but no one knows what the can is for. When they restored the tractor the can was removed, cleaned, painted, and put back on. Certainly a little larger than a pork and beans can for size, but smaller than a quart fruit jar. I told him it could have been for an pump oil can, small tools, spare spark plugs, who knows? Any ideas what the can might have been used for on a John Deere 520?????? I will pass on what you guys think. Thanks.
