Push Mowers on Lawn Care Trailer

For my 2014 trailer setup I need a way to secure my push mower(s) in between lawns. I will be going pretty slow, so it doesn't need to be much, though.

I was thinking about getting something like this, but I think $35 is too expensive for a piece of metal! Jungle Jim's Accessory Products | Transport Lockdowns | Jungle Boot Small

Any homemade designs, or should I use bungee cords or something?
