Hi Jason, yes mate, the 590 was unusual in many respects; same cutting width as the Model 430, had a smaller engine ...the 430 was 3 HP. and the 590... 2.5 HP; the 430 has a cutter clutch; the 590 was a squeeze and go clutch....and a failure! Here's its specs; In fact, it's the 430's little brother and not as good!
