Our first mower was a three gang jacobson. I bought this one from a golf course in PA, it's a Toro as Kenny D said. It's not quite as good as the Jacobson units, but it's 15 foot wide versus 6. We've pulled this with Kenny's tractor, my 4400, my B and an IH-340 I had a few years back. It really needs 25-30 HP to pull, especially when the grass is a bit tall. My one wheel drive F-250 won't pull it under many conditions. The bad part is, it cuts many many acres per hour. Hardly enough time to finish one beer and I'm done with the field...

TurfNet.com - The TurfNet Media Network has used turf equipment on it, and the prices are way better than anything I've seen on Fleabay.
