Both the plows I just repainted have depth wheels on them and that causes an issue when they aren't on the tractor. They are quite 'tippy', wanting to fall over at the slightest movement. This can be an issue, especially if they are at a show. Someone could get hurt if a plow fell on them. So I studied the problem and came up with this solution.
The first pic shows the blocks I have now under the depth wheels to keep them up.
I had some thin strap that I bent to hang of the top of the share. I drilled a hole through these to bolt to some extra chunks of lead I have.
Here they are hanging on the shares.
Notice the wood blocks are removed from under the depth wheels. They are both very steady and it would take a lot to make them fall over now.
