Took the 2186 to the closest dealer for Rim Guard, a liquid tire ballast. Center of gravity is much more stable now, and traction has increased greatly. Handles a lot more like the old Cub now. Pulled some fallen trees from the woods uphill and it worked beautifully.
Picture is gross isn't it! Rim Guard is just beet juice really, so that's why the organic color (and smell). This pic was taken after he took the fill valve off.
