I use both a TB and Swisher in out firewood operation. The TB is slooowww, like 18/19 seconds, it uses a 5hp honda and 11 gpm pump, the Swisher is twice the splitter the TB is, it is using a 16 gpm pump runs a cycle time of around 14 sec.
The wedge design on the swisher is also a much more efficient design. My Troy-Bilt is for sale and I'm going to go with a Super Split.
Take a hard look at the Swisher, I've found it to be an excellent machine, very capable of being used in a small commercial operation.
The Troy-Bilt is okay for a guy that splits wood for himself family and friends, mine has split way north of 240 cord and has blown one engine (covered under warranty) and it seems the second stage has stopped working in the pump (I've got to replace).
