While bungee cords may seem like an easy and affordable option for securing your mowers, they are not recommended. Bungee cords can stretch and lose tension over time, which can cause the mowers to move around during transport. They also can't hold heavy mowers securely and can't be tightened easily. It's best to use ratchet straps, faststraps or 2x4s bolted to the floor or a 2x4 box for the wheels to sit in for securing mowers.
