What’s the reason a wheeled backhoe is nicknamed a ‘rubber duck’?

[Mr. McTuggart]

Hey everyone, I've been digging into different types of backhoes, and I keep seeing people call a wheeled backhoe a 'rubber duck.' I get that it's probably because of the tires, but I'm curious-why exactly is it called that? Is it just a nickname in the construction world, or is there a deeper reason behind it? Also, are there differences in usage or performance between a rubber duck and a standard tracked backhoe that I should know about?"

The nickname "Rubber Duck" is almost exclusively used for wheeled 360-degree excavators, rather than the standard tractor-style backhoe loaders (like a JCB 3CX).
