John Deere power-flo system. Fits the 300 series with either the 48" or 54".
It's pictured on my 390, but it is currently taken off and in my shed. I just don't use it anymore. Works good. Bags are good. Very low hours, my old house had a backyard pool, so I'd really bag roughly 0.25 acre so we wouldn't track grass in the water...then I'd take it off to do the rest of the lawn without it. The only thing you will need to buy extra is the double drive pulley for the deck.
Tractor not included unless you want it too and we can work something out.
Email me with your number and I'll get back to you.
