511 Backhoe - Swing Cylinders

[Farmerboy]

Simple question: how does the boom on the 511 backhoe swing; with opposing hydraulic cylinders or via a single hydraulic cylinder connected via chain?

I've got a 3716 backhoe that swings via a single cylinder which is connected to the boom via a chain - not real crazy about the design.

The 485, 595, 509, and 511 Mahindra ho's are all made by BradCo, and all have dual cylinder on the swing... Any second now, my little sister will chime in and let us know for sure........ [ Or repremand me for my errant ways..... ]
